Abstract:

Through analyzing the molding process characteristics of cold-formed steel sheet piling, mechanical testing and metallographic analysis was made on the curved position of the U-shaped cold-formed steel sheet piling , the following conclusions was drawn: Cold formed steel sheet pile was subjected to the complex cross-section cold roll forming process, resulting in the uneven performance of a steel sheet piling along the horizontal. For the open cold formed steel of asymmetric steel sheet piling and complex cross section, a simple test at flat panel location is difficult to represent the overall performance of cold-formed steel, therefore it is necessary to make a comprehensive performance test on locking. A test method to check the locking occlusion performance on the cold bending steel plate is put forward. The experimental tensile strength of the Q235 level of ordinary carbon steel production of cold-formed steel sheet piling locking bite is 66MPa.

Abstract:

The dependence of the young modulus of metals and alloys on the high temperature must be taken into account in metallurgy in the hot rolling of steel sheet on sheet-rolling mills, hot flattening of steel sheet in the sheet straightening machines, press forming forgings from hot steel sheet, hot volume stamping of metal products, and so on. For example, on the mill 5000 by SMS Siemag, the sheet-rolling of steel strips from the hot slabs at the stand Quarto (the maximum force of 120 MN) occurs at a temperature from 750 °С to 1050 °С, but the pre-flattening of hot steel strip on the five-roller sheet-straightening machine by SMS Siemag occurs usually in the temperature range from 600 °С to 760 °С. In this paper, based on the analysis of experimental data about the dependence of the young modulus for various steel alloys, the analytical dependence of the young modulus on temperature is obtained.

Abstract:

Models are established for oval tube hole clad steel tube sheet and circular tube hole clad steel tube sheet. Finite element analysis software ANSYS Workbench is used. Stress distribution characteristics of tube sheet with oval tube hole are investigated. Stress distribution characteristics under different ellipticity are analyzed and the general law of stress distribution of oval tube hole clad steel tube sheet is summarized. Results show: effects of tube hole shape on stress of clad steel tube sheet mainly focus in the tube zone, oval tube hole could effectively improve the phenomenon of stress concentration at the connection of basic layer and clad layer. When tube hole is oval, the maximum values of thermal stress and mechanical stress increase comparing to clad steel tube sheet with circular tube hole. With the increase of ellipticity, the total stress of tube sheet increases, stress increases on the minor axis of tube hole and decreases on long axis, and the deviation between the two stresses increases. The results provide reference for the design of the clad steel tube sheet.

Abstract:

In this paper, a corrosion inhibitor containing nitrogen atoms and a conjugated π bond was synthesised, and its final product synthesised by the optimal conditions of the orthogonal test results is named multi-mannich base (MBT). The corrosion inhibition effect on the N80 steel sheet of the corrosion inhibitor was evaluated in a CO2 saturated solution containing 3 wt % NaCl; the corrosion rate was 0.0446 mm/a and the corrosion inhibition rate was 90.4%. Through electrochemical and adsorption theory study, MBT is a mixed corrosion inhibitor that mainly shows cathode suppression capacity. The adsorption of MBT on the surface of the steel sheet follows the Langmuir adsorption isotherm; it can be spontaneously adsorbed on the surface of the N80 steel sheet, which has a good corrosion inhibition effect. The surface of the N80 steel sheet was microscopically characterised by atomic force microscope (AFM). It can be seen from the results that the N80 steel sheet with MBT added is significantly different from the blank control group; the surface of the steel sheet is relatively smooth, indicating that MBT forms an effective protective film on the surface of N80 steel, which inhibits the steel sheet.

Abstract:

This study analysed the business sustainability of remanufacturing waste steel sheet from the shells of end-of-life vehicles into mesh steel sheet for manufacturing sheet-metal products. Hybrid statistical, fuzzy, and overall sustainability-index curve-fitting models were used to analyse the technical, economic, environmental, management, and social feasibility of remanufacturing, where the sales price, eco-cost savings, and CO2 emission reductions were used as typical statistical indicators. The remanufacturing process was optimised to allocate hardware for a plant recovering 480 m2/shift of waste sheet steel and producing 2851–5520 m2/shift of mesh sheet steel. Six scenarios were used to model the sustainability parameters to normalise the sustainability index values. The sustainability index of each parameter was calculated by multiplying its weight of importance by its weight of satisfaction. The highest sustainability index of 0.95 was calculated for the economic feasibility index, while the lowest sustainability index of 0.4 was calculated for the management feasibility. Remanufacturing of waste sheet steel into mesh sheet steel can be applied with an estimated overall sustainability index of 0.88.

Full text

Abstract:

A confocal micro-X-ray fluorescence (XRF) method with a vacuum chamber was used for investigation of underfilm corrosion that occurs on a painted steel sheet used for automotive applications. A painted steel sheet was prepared by applying electrodeposition coating onto an electro-galvanized steel sheet with a zinc phosphate conversion coating. The spatial resolution of the confocal micro-XRF was about 10.9 ?m at an energy of 17.4 keV. The phosphorus signal from the zinc phosphate layer was able to be observed nondestructively by measuring under the vacuum condition. Each layer of the painted steel sheet was observed from the depth profile analysis of the characteristic elements of each layer. The painted steel sheet was scratched to expose the substrate surface, and then the sheet was then immersed in a NaCl solution for 10 days. The in-depth elemental map of Ti of the corroded steel sheet revealed blister-type corrosion around the scratch. The in-depth elemental maps of Zn and P suggested that the zinc phosphate layer dissolved from the scratched part into the NaCl solution.

Abstract:

The high-temperature oxidation kinetics of Galvalume-coated steel sheet and Q235 steel sheet were studied by thermogravimetric analysis (TGA). A new diffusion equation was deduced and used to investigate their kinetic mechanism. The characteristic time (tc) in the equation can be expressed as a function of temperature T, diffusion coefficient D0, thickness of the steel sheet H, etc. The calculated result showed that the oxidation reaction rate of Galvalume-coated steel sheet was slower than that of Q235 steel sheet through comparing the values of tc. Besides, the oxidation reaction rate increased with the temperature rising from 750 to 850 °C. Compared our experimental data with the theoretical value calculated by the new function, a good agreement has been obtained.

Abstract:

As a newly developed pile foundation, the snowflake shaped steel sheet pile is composed of three Y-shaped sections with an included angle of 120° and has a large specific surface area, which can give full play to the side friction of pile and improve the bearing capacity of single pile. At the same time, the snowflake shaped steel sheet pile has a high strength, relatively few materials, and it has good prospects with engineering applications. In order to accurately grasp the mechanical characteristics of the snowflake shaped steel sheet pile, this paper carried out the model test of snowflake shaped steel sheet pile based on OFDR (optical frequency domain reflector) distributed optical fiber sensor technology. The results show that: (1) OFDR distributed optical fiber sensing technology can effectively monitor the strain of snowflake steel sheet pile; (2) under the vertical load, the strain of snowflake steel sheet pile decreases along the length of the pile; (3) the strain of the same section of snowflake steel sheet pile is different at different positions, the strain at the junction between web and web is basically the same as the junction between web and flange, and the strain of the pile shaft on the flange edge is larger.

Abstract:

Powdering and desquamation is prone to happen when galvannealed sheet steel is stampinged and Powdering or desquamation often happens at the fragile phase where Fe content is high. The fragile phase thickness of the coating of galvannealed steel sheet is correlative nearly to the coating anti-pulverization ability.So it is very important to measure the fragile phase thickness with the research of galvannealed sheet steel process. The fragile phase thickness of the same batch galvannealed sheet steel made by some steel plant is about 560~590nm when it is measured by glow ischarge spectrometer , fracture observation methods by SEM and metallographic microscope, the error is very little.

Abstract:

AbstractTo increase the usage of high-strength steel and aluminium alloy sheets for lightweight automobile body panels, the joinability of sheet combinations including a 780-MPa high-strength steel and an aluminium alloy A5052 sheets by mechanical clinching and self-pierce riveting was investigated for different tool shapes in an experiment. All the sheet combinations except for the two steel sheets by self-pierce riveting, i.e., the two steel sheets, the two aluminium alloy sheets, and the steel-aluminium alloy sheets, were successfully joined by both the joining methods without the gaps among the rivet and the sheets. Then, to show the durability of the joined sheets, the corrosion behaviour and the joint strength of the aged sheets by a salt spray test were measured. The corrosion and the load reduction of the clinched and the riveted two aluminium alloy sheets were little. The corrosion of the clinched two steel sheets without the galvanized layer progressed, and then the load after 1176 h decreased by 85%. In the clinched two galvanized steel sheets, the corrosion progress slowed down by 24%. In the clinched steel and aluminium alloy sheets, the thickness reduction occurred near the minimum thickness of the upper sheet and in the upper surface on the edge of the lower aluminium alloy sheet, whereas the top surface of the upper sheet and the upper surface of the lower sheet were mainly corroded in the riveted joint. The load reduction was caused by the two thickness reductions, i.e., the reduction in the minimum thickness of the upper sheet and the reduction in the flange of the aluminium alloy sheet. Although the load of the clinched steel without the galvanized coating layer and aluminium alloy sheets decreased by about 20%, the use of the galvanized steel sheet brought the decrease by about 11%. It was found that the use of the galvanized steel sheets is effective for the decrease of strength reduction due to corrosion.

Abstract:

Crack universally existing underground is an important kind of pores. In order to study the elastic wave propagation in fractured medium through experiment, a new method to make artificial core with certain cracks using oil well cement and camphor sheet or thin steel sheet is put forward. Geometric parameters of the crack, such as shape, size and aspect ratio, are approximately equal to that of camphor sheet or thin steel sheet. Using the thin steel sheet to make crack can be more easy and accurate to control the crack angle than using camphor sheet. The crack opening scales at millimeters. The aspect ratio of cracks formed by camphor sheet ranges from 1.4 to 8, and aspect ratio of cracks formed by thin steel sheet ranges from 2.5 to 70. This method is proved simple and feasible by experiment practice, which can provide artificial cores with certain crack for acoustic wave propagation study.

Abstract:

In this work structured sheet metals were investigated using electrochemical measurement techniques. The main purpose is obtaining fundamental information about the corrosion resistance of structured sheet metals in comparison to smooth sheet metals as well determination of the influence of the structuring process on the corrosion properties. The corrosion resistance of structured sheet metals is affected by manufacturing process. One of the main influence factors is the change of the surface roughness. In this study the low carbon steel DC04 and the stainless steel 304 (X5CrNi18-10) were investi-gated. The electrochemical tests were carried out in 3%-NaCl solution. Potentiodynamic linear polarization was used to determine such electrochemical characteristics as the free corrosion potential, the corrosion current, the pitting and protection potential. Furthermore, the corrosion rate was calculated for smooth and structured sheet metals of the low carbon steel DC04. For the stainless steel 304 the pitting density was estimated. The surface roughness was measured for both materials. The electrochemical corrosion tests show a small difference in the corrosion behaviour of structured and smooth sheet metals. Structured sheet metals have a lower corrosion resistance than smooth sheet metals. The steel DC04 shows the worst corrosion properties at the structure location “negative” in comparison to the structure location “positive”. The corrosion resistance of the stainless steel 304 is better at the structure location “negative” than at the structure location “positive”. Moreover, the results show the correlation between the surface roughness and the corrosion resistance for structured sheet metals.

Abstract:

This paper is a study on the compositional change of steel sheet according to the heating temperature using portable XRF. Color coating galvanized iron (CCGI), galvanized iron (GI), galvalume steel (GL), and electrolytic galvanized iron (EGI) often used in prefabricated buildings and interior design are selected as test samples, and the steel sheet is heated using a sand burner for 1800 s. According to the method, the compositional change of the steel sheet was measured and analyzed. As a result of the experiment, in the case of samples oxidized for 1 day after non-watering, the components with low melting points such as Zn and Al decreased according to the heating temperature of the steel sheet, and therefore the components of Fe with relatively high melting points increased high. In the case of the sample oxidized for 7 days after watering, the steel sheet damaged by the heating temperature reacted with water and the Fe component was measured to be higher. The possibility of predicting the heating temperature of the steel sheet through the change of the composition ratio of constituent elements was confirmed when portable XRF was used for fire investigation.

Abstract:

Self-piercing riveting (SPR) is a suitable technology to join various materials and has attracted more attention in the automotive industry. In this work, the effects of forming parameters on the forming qualities and mechanical properties of B1500HS steel/AA5052 aluminum alloy SPR joints were analyzed. The results show that the sheet stack sequence has little influence on the peak tensile load and rigidity of SPR joints. When the steel sheet is placed on the aluminum sheet, the failure displacement, energy absorption, and ductility factor are, respectively, 2.77, 2.13, and 2.28 times larger than those of the joints with the aluminum sheet placed on the steel sheet. The SPR joints with steel sheets placed on aluminum sheets have better mechanical stability. Meanwhile, when the steel sheet is placed on the aluminum sheet, the fatigue life of the joint can be increased by about 98.4%, 88.3%, and 118.1%, respectively, under high, medium, and low fatigue loads. A joint with opposite riveting direction has the optimal fatigue performance and the fatigue life is 1.64 and 2.14 times those of the other two-rivet joints. Generally, the fatigue fractures of aluminum alloy sheets in SPR joints occurred in fatigue tests. The fatigue fracture of a joint with a steel sheet stacked on an aluminum sheet extends uni-directionally to the edge of the sheet from the riveting point, while a symmetric fatigue crack of aluminum occurs for joints with the opposite sequence. The distribution of fatigue cracks is related to fatigue load, and fatigue cracks mainly originate in the fretting wear area of the contact interface between the rivet leg, upper sheet, and lower sheet.

Self-pierce riveting of three thin sheets of 980 MPa steel and 5052 aluminum alloy was performed to investigate the effect of sheet configuration on the deforming behaviors of the sheets and the rivet and joint strength. When the lower sheet was aluminum alloy, the joining range was relatively wide, i.e., the interlock hooking the rivet leg tended to be large. In the sheet configuration in which the upper and lower sheets were A5052 and the middle sheet was 980 MPa steel, the rivet leg spread out moderately and the joint without defects was obtained. In the lower 980 MPa steel sheet, fracture tended to occur due to the low ductility of the lower sheet, and the joining range was narrow with the small interlock although the three sheets were joined by an appropriate die shape. In joint strength of joined three sheets, fracture occurred in the lower-strength aluminum alloy sheet if interlocks of about 300 μm and 150 μm could be formed in the lower aluminum alloy sheet and 980 MPa steel sheet, respectively.

Abstract:

The chemical composition and production process of a new kind of enameling steel sheet used for heat-exchanger were introduced. The microstructure, mechanical property and hydrogen permeation resistance of the steel sheet were studied. The enameling adherence and pin-hole ratio of the enameled steel sheet were measured. The results show that the microstructure is ferrite with the grain size of grade 11 and quantities of linear MnS inclusions, grainy manganese-niobium composite oxides and small NbC precipitates are formed in the steel. The average value of hydrogen permeation resistance of the steel is 33 min·mm-2, the enameling adherence is evaluated as level A1and the number of the pin-hole defects in the enameled steel is less than 10 per square meter. Both mechanical property and enameling quality of the steel sheet meet the technical demand of heat-exchanger.

Abstract:

Cladding is the bonding together of dissimilar metals. One of clad products is the titanium clad steel sheet. It is effective to cover with pure titanium sheet to improve the corrosion resistance of the steel sheet. Titanium clad steel sheets are often achieved by rolling sheets together under high pressure. In the current study, the blank comprising three laminar non-bonded sheets, such as the titanium/steel/titanium sheet, is arranged in the die. The formability of pure titanium clad sheet by multistage deep drawing was investigated to enhance corrosion resistance of steel cup. In the experiment, the blanks were pure titanium sheets JIS1-TP270, JIS2-TP340, ultralow-carbon steel SPCC, and stainless steel SUS316L. The initial thickness of the sheet was 0.2 to 0.5 mm in thickness. The blank diameter was 70 mm. The blanks are merely adjacent sheet; however, not joined with each other. In the deep drawing process, a hydraulic press was used in the experiment and the forming speed for the press was about 10 mm/min. The lubricant used was the solid powders of molybdenum disulfide. For the prevention, pure titanium blank was treated by oxide coating. The conditions of heat treatment were annealed at 973 K for 3.6 ks to 7.2 ks. By oxide coating, the titanium sheet has sufficient ability in preventing the seizure in multistage deep drawing. The drawn cups of the three-layer laminated sheet were formed. The seizure did not cause. The oxidatively-treated titanium sheets have sufficient ability in preventing the seizure. In addition, the clad cups until 6th stage were formed by multistage deep drawing. Long clad cups were successfully formed in multistage deep drawing process.

Abstract:

Ultrasonic welding between SS400 mild steel sheet and aluminum alloy A5052 sheet containing magnesium was conducted. In this study, authors investigated the influence of ultrasonic welding condition on the mechanical properties and the interface microstructure of a joint, and examined the effect of an insert metal to improve the joint strength. The main results obtained in this study are as follows. It was possible to ultrasonically weld SS400 mild steel sheet and A5052 sheet. When the clamping force was varied keeping the welding time constant for 1s, the joint strength showed the maximum at the clamping force of 588N and it decreased with increasing the clamping force because the frictional action at the interface decreased with it. When the clamping force was kept constant at 588N and the welding time was varied, the joint strength reached the maximum at the welding time of 2.5s, followed by decreasing in the joint strength welded at 3s welding time due to the formation of Fe2Al5 intermetallic compound at the interface. Using insert metal of commercially pure aluminum successfully improved the joint strength and the strength of the joint welded at 3s welding time was about three times larger than that without the insert metal.

Abstract:

For some electrostatic precipitators, profiled steel sheets are used as casing wall which is subjected to both bending and vertical compression. By nonlinear finite element method, the influences of structural parameters on load bearing capacity of profiled steel sheet wall were investigated. For the loading path, the uniform transversal pressure was applied firstly, and then the vertical compression was applied until the wall failed. The results indicate that the vertical compression resistance of profiled sheet decreases with the transversal load or the increasing sheet span. For certain sheet shape, the vertical compression resistance of profiled sheet decreases with the wall width increasing. The vertical resistance of the profiled sheet whose tensioned flanges are connected with the side columns is more than that whose compressed flanges are connected with the side columns. When the vertical compression resistance is calculated according to the buckling evaluation method of cold-form thin-walled steel member, the value is usually less than the solution from finite element method. Consequently, the load bearing capacity based on the related method of cold-form thin-walled steel member can be taken as a reference solution for the profiled steel sheet subjected to combined bending and vertical compression.

Abstract:

In this paper, using high tensile strength and yield strength of hot-rolling acid washing thin steel sheet instead of cold-rolling steel sheet as the vehicle frame is investigated. The high pure and finer grain steel can be obtained by deep deoxidation technology, deep desulfurization technology, low nitrogen and microalloy-technology of Boron/Niobium/Titanium. High yield strength (σs>340 MPa) and high specific elongation hot-rolling thin steel sheet have been produced in the EAF-CSP short flow product line. The mechanical property, shape, surface quality and tolerance of steel sheet after hot-rolling can be controlled by optimizing joining-casting-rolling and controlling-rolling-cooling technology. Based on the forming test, cold-bending test, welding test and fatigue test results, it can be seen that cold-bending property, forming ability and fatigue strength of hot-rolling acid washing steel sheet is better and meet the product requirement of vehicle frame. This investigation can resolve the fracture problems of QUANSHUN vehicle, improve the working life, provide reliable automobile and reduce the production cost.

Abstract:

The conventional structural design of wallboard of electrostatic precipitator casing uses the wall structure of stiffened flat sheet which consumes a great amount of steel. Consequently, a new structural idea was explored to optimize the conventional design which applied profiled steel sheet and located wall beam and wall column. The codes were written which designed and analyzed the wall structure of casing. On the basis of a practical project, as the design parameters were varying, the codes were used to automatically compute the strength, stability, stiffness and steel consumption of profiled steel sheet, wall beam and wall column of the corresponding design case. Then, the design with the minimum steel consumption was selected as the optimum one among all the cases which could satisfy the design requirements. The characteristics of the optimum section shape were generalized. The influence of structure layout on the minimum total steel consumption of casing wall structure was investigated. The total steel consumption of casing wall structure is comparatively small when wall column and wall beam divide the whole wallboard into several smaller blocks whose aspect ratio is about 1.6-2.9. Compared with the original wall structure of stiffened steel sheet, the optimized wall structure composed of profiled sheet, wall column and wall beam can save steel significantly which can be applied widely in large-scale electrostatic precipitator casing structures.

Abstract:

Given the structural stability of steel sheet pile support in a water-rich soft soil area, the interaction mechanical mechanism between steel sheet pile support and soft soil was analyzed in the paper. Based on the limit equilibrium theory of soil mass and the coordinated deformation effect of retaining structure and soil, the force equation and action coefficient considering the cohesion of soil and the friction angle of steel sheet pile to soil were obtained. According to the characteristics of the soil around the foundation pit, reasonable supporting spacing (d = 4 m) could be obtained considering the friction angle of the steel sheet pile to soil properly without the cohesion of soil. The monitoring results show that the axial force during the support process is more reasonable considering the cohesion of soil and the friction angle of interaction with the wall and soil. The axial force of the measuring point was affected by the construction site and the layout of the utility tunnel foundation pit. The location with large deformation of the steel sheet pile and the most unfavorable range from the top of the foundation pit was 0.5–0.7 H. For the mechanical analysis of the interaction between steel sheet pile and soil, the apparent cohesion and friction angle can be taken as 0.05 rH and φ/3–φ/2, respectively. The foundation pit in the water-rich soft soil area could operate stably with a better waterproof effect by the steel sheet pile under different working conditions.
