Abstract:
High strength steels, such as austenitic stainless steel, Transformation Induced Plasticity (TRIP) steel and silicon steel, have significant work hardening during cold rolling, which in turn induces a quickly increased rolling force. Tension plays a very important role in the reduction of the rolling force. However, coiler tension control system used in the classic experimental rolling mill requires long-scale strip, which cannot be satisfied for most experimental cases. To overcome this drawback, a new pilot rolling mill has been developed. The horizontally located hydraulic cylinders and clamps have been used to apply tension to the rolled short-scale strip. With this rolling mill, the austenitic stainless steel strip, TRIP steel strip and other high strength strips have been studied.

Abstract:
An effective and efficient production method of narrow and thin strips made of steel, non-ferrous metals and their alloys is wire flattening in a ball rolling mill. In this device cylindrical rollers have been replaced with balls of diameter ca. 15 mm. Proper selection of deformation process parameters enables to obtain strips with the required geometrical characteristics. Experimental planning method was applied to evaluate the influence of flattening process technological parameters on strip geometrical features. Statistical analysis enabled to determine mathematical models of stainless steel 5XCrNi18-10 strips flattening. It was established that strip widening depends on ball roughness, draft applied, relation of wire diameter to ball diameter, back-tension stress. Strips flatness depends on draft applied. It was observed that strips feature uniform thickness over their width, parallel flat surfaces, narrow dimensional tolerance, high quality surface and naturally rounded edges.

Abstract:
Waste recycling of both ferrous and non-ferrous metals is a useful process for the economy of any country. This paper proposes a new technology for recycling bar scrap of ferrous metals by rolling it in radial-shear rolling mills by producing a commercial product in the form of bars with an ultrafine-grained gradient structure. Studies have shown that the deformation of bar scrap in the form of pieces of reinforcement made of steel grade 18G2S in a radial-shear rolling mill makes it possible to significantly disperse its structure by producing a gradient ultrafine-grained structure, and this, in turn, leads to the elevating of the mechanical characteristics of this steel grade. Thus, the tensile limit of the 18G2S grade steel deformed on the radial-shear rolling mill was 620 MPa (at the initial value of 365 MPa).

Abstract:
Due to the influence of rolling force fluctuations, tube size changes and material uniformity and other factors, vibration and other phenomenon inevitably occur in the rolling process of tandem rolling mill. This vibration has a great impact on the dynamic stability of the mill and rolling reduction, and will significantly reduce the dimensional accuracy and surface quality of seamless steel pipe. In this paper, the non-linear finite element software ABAQUS is used to simulate the rolling process of seamless steel pipe. First, rolling force of the first frame with the maximum rolling force of PQF rolling mill is calculated. The reliability of rolling force calculated by the finite element method is verified by the test experiment. The dynamic response analysis of the roll is carried out to obtain the dynamic response curve of the roll in the rolling state and to provide technical support for the rolling schedule with the calculated rolling force being the load.

Abstract:
The conditions of production and the most relevant directions of development of technology and equipment of cold rolling mills for the production of thin flat rolled steel are investigated, analyzed and summarized. A comparative analysis of cold rolling technology is carried out, which is implemented in continuous and reversed modes of mill. The technological limitations and criteria for the development of deformation modes on cold rolling strip mills, which allow to expand the assortment towards a smaller thickness, are given. A method for determining the thickness is proposed, and a series of thicknesses of thin (1.5-1.8 mm) hot-rolled break-down are recommended for the production of tinplate of single rolling and thin strips of high quality. The method of calculation schedule drafting on a specific mill is developed. The technique of determination of the smallest thickness of a strip on a concrete mill is presented, taking into account the influence of rigidity of the working cage and features of the force load of the roller node with a decrease in the thickness and width of the strip. The use of the above materials allows to select and justify the optimal variant of cold band rolling technology, as well as to develop rational deformation modes that ensure the implementation of the cold rolling process with maximum efficiency, given the desired range and the required volume of thin cold-rolled sheet steel or tinplate. As a result of taking into account the features of the force interaction of the thin strip with the rolls during cold rolling and the rigidity of the working stands of the mill, the accuracy and reliability of determining the parameters are increased, it opens additional possibilities for expanding the range of cold rolling mills towards smaller thicknesses.

Abstract:
Considering the problems and details of modeling process of cold rolling, it was constructed a theoretical model of deformation area based on a set of equations, which were practical testing. The model is based on cold-rolled numerical solution of differential equations of forces equilibrium in the deformation area by Karman. In the model there are included modules for calculating strip temperature and strip gage at the exit from the stand, considering elastic recovery of the strip. For adaptation of the equations to the specific conditions of cold rolling of HSLA steels in the continuous five stand mill 2030 and assess the deviation of calculated data from the actual, a procedure of correction for hardening curve of rolled steel has been developed. The model allows defining the energy-power parameters of rolling: average unit rolling force, the full force of rolling, rolling moment, rolling force, an average temperature of strip at the inlet and outlet of each of the mill stands, steel hardening curve when rolling. The model is implemented as software using object-oriented approach in the language of C++ Builder.

Abstract:
The steel production is a highly capital and energy intensive industry that due to recent raw materials’ price increase and lowered demand, it has been squeezed and forced to look more deeply on how to add value to the customer at lower operative costs. The project was carried out on site at the ArcelorMittal’s millin Esch-Belval, Luxembourg which comprises an integrated melt shop, continuous casting plant and the rolling mill with the objectives of proposing optimization rules for the cold sector of the rolling mill and to analyze the impact of the future truckbay shipment area. The course of action followed was to draw a Value Stream Map (VSM) in order to understand the plants’ current status and serve as a roadmap to build a discrete event simulation model that after its validation, served as a support tool to analyze what-if scenarios. Similarly, a current status analysis of the  shipment/stock area was conducted collecting statistics about potential truckshipments and finally proposing a series of recommendations for its operation. The main proposed solutions to optimize the rolling mill’s cold sector were:(a) Integer programming model to globally optimize the scrap level when cutting the mother beams to customer size beams. (b) Updating pacemaker parameters and (c) Local process time improvements. Concerning the future truck loading, the simulation model was used as a support tool to dimension the transition area between the cranes’ and forklift operations resulting in a 6-9 bundles buffer capacity. Additionally, the current length-based storage policy was found to have competitive objectives so a turnover class-based storage policy is proposed with A, B, C classes which should provide an improved organization of the stock and travel distance of the cranes. The evaluation of the cranes’ performance remains an issue since there are currently no objective measures like, for instance, travelled distance. Optical measuring devices are suggested as one option to have a performance indicator that would help further investigate root cause problems in the shipping/stock area.

Abstract:
Includes bibliographical references (leaves [105]-110).
The microstructural evolution of AISI304 stainless steel in the Steckel mill rolling process is investigated. This study includes the analysis of mill logs, microstructural examination of the mill product, deformation simulations and post deformation heat treatments. The mill logs from industry contains information about various process variables such as temperature, roll speed, dimensions of the mill strip and forces applied to it during the hot mill rolling process. The strain, strain rates and stresses on the mill strip can be calculated from the mill logs. An understanding of the metallurgical changes during rolling process can be gained by analysing the mean flow stress trends that evolve during rolling. Microstructural examination of the strip in different regions allows us to evaluate the property variations in the strip. This was done with microhardness testing, conventional optical microscopy and electron backscatter diffraction. The middle section of the strip demonstrated full recrystallization whereas the head and tail sections demonstrated no signs of recrystallization. The property differences through thickness proved to be negligible. Laboratory simulation was done in uniaxial compression testing on a Cam Plastometer. It was found that the temperature has a profound influence on the flow stress and the microstructure. The strain rates experienced in hot rolling does not have a significant effect on the flow stress and no measurable effect on the hardness. Heat treatments were done on the deformed uniaxial compression samples. The results of these heat treatments were analysed by two different methods: to deform the sample again after the heat treatment and to compare the yield stress from the first and second deformation and to measure the changes in room temperature hardness with the heat treatment time. The latter led to the development of a time to 50% recrystallization equation that allows the prediction of a direct annealing time for complete softening at the conclusion of the hot rolling process.

Abstract:
Constitutive behavior models for steels are typically semi-empirical, however recently neural network is also being used. Existing neural network models are highly complex with a large network structure i.e. the number of neurons and layers. Furthermore, the network structure is different for different grades of steel. In the present study a simple neural network structure, 3:4:1, is developed which models flow behavior better than other models available in literature. Using this neural network structure constitutive behavior of 8 steels: 4 carbon steels, V and V-Ti microalloyed steels, an austenitic stainless steel and a high speed steel could be modeled with reasonable accuracy. The stress-strain behavior for the vanadium microalloyed steel was obtained from hot compression tests carried out at 850-1150 C and 0.1-60 s-1. It is found that a better estimate of the constants in the semi-empirical model developed for this steel could be obtained by simultaneous nonlinear regression. A model that can predict the effect of chemical composition on the constitutive behavior would be industrially useful for e.g., in optimizing rolling schedules for new grades of steel. In the present study, a neural network model, 5:6:1, is developed which predicts the flow behavior for a range of carbon steels. It is found that the effect of manganese is best accounted for by taking Ceq=C+Mn/6 as one of the inputs of the network. Predictions from this model show that the effect of carbon on flow stress is nonlinear. The hot strip mill at Jindal Vijaynagar Steel Ltd., Toranagallu, Karnataka, India, was simulated for calculating the rolling loads, finish rolling temperature (FRT) and microstructure evolution. DEFORM-2d a commercial finite element package was used to simulate deformation and heat transfer in the rolling mill. The simulation was carried out for 18 strips of 2-4 mm thickness with compositions in the range and 0.025-0.139 %C. The rolling loads and FRT could be calculated within 15 % and 15 C respectively. Analysis based on the variation in the roll diameter, roll gap and the effect of roll flattening and temperature of the roll showed that an error of 6 % is inherent in the prediction of loads. Simulation results indicated that strain induced transformation to ferrite occurred in the finishing mill. The microstructure after rolling was validated against experimental data for ferrite microstructure and mechanical properties. The mechanical properties of steels with predominantly ferrite microstructures depend on the prior austenite grain size, strain retained before transformation and cooling rate on the run-out table. A parametric study based on experimental data available in literature showed that a variation in cooling rate by a factor of two on the run-out table gives rise to only a 20 MPa variation in the mechanical properties.

Abstract:
Estudaram-se os efeitos da fração volumétrica de carboneto eutético e da dureza da matriz sobre a resistência à fadiga térmica de ferros fundidos brancos multicomponentes. Utilizaram-se ligas do sistema Fe-4Cr-V-2Mo-2W-2C, V variando entre 5 e 8% e Fe-4Cr-8V-Mo-2W-2C, Mo variando entre 2 e 5%. Corpos-de-prova com a geometria de discos com seção variável foram temperados e revenidos para obtenção de dois valores de microdureza da matriz: 450 HV e 650 HV. Conduziram-se ensaios de fadiga térmica por 100 e 500 ciclos. Cada ciclo envolveu aquecimento por indução da superfície até a temperatura de 600°C em 10 segundos e subseqüente resfriamento em água por 45 segundos (equalização das temperaturas do núcleo e da superfície). Os corpos-de-prova foram caracterizados antes e após os ensaios de fadiga térmica. Antes dos ensaios, caracterizaram-se os carbonetos eutéticos (tipos, morfologia, fração volumétrica, tamanho, forma e distribuição dos carbonetos) e a microdureza da matriz. Após os ensaios, caracterizaram-se as trincas de fadiga térmica macroscópicas e microscópicas (número e profundidade) e a microdureza da matriz. A nucleação de trincas de fadiga térmica ocorre predominantemente na superfície do corpo-de-prova, induzidas por concentradores de tensão mecânicos e metalúrgicos. As trincas nucleiam na matriz (a rugosidade age como concentrador de tensão mecânico) e em carbonetos (interface carboneto/matriz ou no próprio carboneto). A taxa de nucleação sofre influência da fração volumétrica de carboneto eutético (seu aumento promove aumento da taxa de nucleação) e da dureza da matriz (seu aumento promove diminuição da taxa de nucleação). A propagação de trincas ocorre predominantemente pela interface carboneto/matriz ou através do carboneto. A taxa de propagação sofre influência da distribuição de carboneto eutético. Quanto maior a relação “continuidade de carbonetos/distância livre média entre carbonetos”, maior a taxa de propagação de trincas. A taxa de propagação de trinca diminui com o aumento do tempo de ensaio, independentemente da fração volumétrica de carboneto eutético e da dureza da matriz. O regime de propagação durante os primeiros 100 ciclos é caracterizado pela propagação instável da trinca controlada pela tenacidade à fratura do material; de 100 a 500 ciclos, a propagação é controlada pela magnitude da tensão. O tamanho do corpo-de-prova também influenciou os resultados dos ensaios: o aumento do tamanho promove aumento das taxas de nucleação e propagação. Este resultado é atribuído ao aumento do gradiente térmico ao longo do corpo-de-prova com o aumento do seu diâmetro.
The effects of the volume fraction of eutectic carbides and of the matrix hardness on the thermal fatigue resistance of multicomponent white cast iron were investigated. Alloys Fe-4Cr-V-2Mo-2W-2C, V ranging from 5 to 8 wt% and Fe-4Cr-8V-Mo-2W-2C, Mo ranging from 2 to 5 wt % were used. Disc shaped samples were quench and tempered for obtaining two matrix microhardness levels: 450 HV and 650 HV. Thermal fatigue tests were carried out for 100 and 500 cycles. Each cycle involved high frequency induction heating of the surface to 600°C and subsequent cooling in water during 45 seconds (equalization of the bulk and surface temperature). The test specimens were characterized before and after the thermal fatigue tests. Before the tests, eutectic carbide (type, morphology, volume fraction, syze, shape and distribution of carbides) and matrix microhardness were characterized. After the tests, the macroscopic and microscopic thermal fatigue cracks (number and depth) and matrix microhardness were characterized. The nucleation of the thermal fatigue cracks takes place mostly at the specimen surface, induced by mechanical and metallurgical stress risers. The crack nucleates at the matrix (roughness as mechanical stress risers as well as at carbides (at the carbide/matrix interface or at the carbide itself). The nucleation rate is influenced by the volume fraction of eutectic carbide (the higher the volume fraction, the higher the nucleation rate) and by the matrix microhardness (the higher the microhardness, the lower the nucleation rate). The crack propagation mostly takes place at the carbide/matrix interface or through the carbide. The propagation rate is affected by the carbide distribution. The higher the “carbide continuity/carbide free path” ratio, the higher the propagation rate. The propagation rate decreases with increasing test time, regardless the eutectic carbide volume fraction and the matrix microhardness. The propagation behaviour during the first 100 cycles is characterized by instable crack propagation controlled by the fracture toughness of the material; from 100 to 500 cycles, the propagation is controlled by the stress magnitude. The syze of the test specimen also influenced the tests results: the larger the specimen syze, the higher the nucleation and propagation rates. This is attributed to the effect of increasing thermal gradient across the specimen with increasing specimen diameter.

Abstract:
This work analysed the role of friction and other process parameters on strip edge drop and width variations during cold rolling of flat steel strips. Comparisons of 3D numerical simulations with experimental datas from rolling trials have shown that roll bite friction is anisotropic: friction in the transverse direction is twice to four times higher than that in the rolling direction. Work roll circumferential grinding striations and the associated roll roughness anisotropy are considered to be responsible for this anisotropy. Moreover by modifying friction anisotropy (decrease of transverse friction for the same longitudinal friction), it is possible to compensate for width narrowing usually observed on commercial cold mills (narrowing is due to strip thermal contractions in the mill interstands). Therefore, friction appears as a suitable process actuator for control of cold rolled product dimensions.

Abstract:
The primary role of rolling oil in cold rolling is to reduce friction at the rubbing interface of the work roll and metal sheet surface. The rolling performance as well as cost effectiveness of rolled products is influenced by quality of the rolling oil. Lubricants are required to function under increasingly stressful operating conditions, so it is a challenge to evaluate the product under simulated conditions to improve the customer confidence in its performance. A steel rolling mill customer had requested us to develop a rolling oil to roll stainless steel in a new 3-stand 18-high rolling mill and demonstrate its performance on an experimental set up. The present paper describes the methodology adopted to assess the suitability of a rolling oil for the particular rolling mill. The screening was carried out with a SRV (Schwingungs Reibungs und Verschleisstest, meaning Vibration, friction and Abrasion) tribometer and EHD (Elasto-hydrodynamic) interferometry based film thickness apparatus to assess the frictional and film forming characteristics of the oil under simulated operating conditions. In addition, simulated tests were carried out on a laboratory 2-Hi Experimental rolling mill to find out the specific roll force (rolling force per unit width of the strip being rolled) required to obtain 55–60% cumulative reduction in three passes as desired by the customer for different grades of stainless steel. Based on results obtained in the laboratory mill simulating industrial test conditions, the product was recommended and was accepted by the customer for use in their rolling mill.

Abstract:
So-called “cluster mills” for cold rolling are currently preferred to prevent strip faults, as the back-up rolls present on the work rolls assure the stiffness required to avoid bending. An effective prediction of dynamic behaviour using an analytical approach is more difficult than for 2 and 4-high mills. The aim of this paper is to find models to simulate operating conditions in cluster mills. Two typical test cases such as Sendzimir and Z-mill are used to detect relevant aspects of dynamics on the experimental signatures, acquired in service. A multi-level approach, based on a core mill model and on some additional models, is proposed to investigate second order approximation problems. Co-simulation with the core model is avoided, as it takes too long. Phenomena, models, available tools and implementation issues are systematically analysed, while a preliminary experimental validation of results, based on available industrial mills, is discussed.
