Abstract:

Introduction. The coastal contamination of the Black Sea has been an important issue for several decades. Heavy metals are the most harmful contaminants which affect people health. The research objective of the present study was to determine the amounts of Cd, Hg, Pb, Cu, and Zn found in the whiting (M. merlangus L.) and the red mullet (M. barbatus L.). These Black Sea bottom fish species have the highest commercial value. The obtained data were used to assess the risk which the fish represents for human consumers. Study objects and methods. The elements were detected using an inductively coupled plasma mass spectrometer (ICP-MS). The amounts of the metals arranged in the following order: Zn > Cu > Pb > Hg > Cd. Results and discussion. The mean values of Cd, Hg, Pb, Cu, and Zn in the edible tissues were 0.013, 0.024, 0.07, 0.195, and 9.05 mg/kg wet wt. for whiting and 0.017, 0.036, 0.05, 0.29, and 6.4 mg/kg wet wt. for red mullet, respectively. These levels proved lower than the permitted values set by the Ministry of Agriculture, Forestry, and Fisheries of the UK (MAFF), Turkish Food Codex (TFC), and EU Commission Regulation. The target hazard quotient (THQ) for all the elements via consumption of whiting and red mullet were also low. Conclusion. Hazard index (HI) was ˂ 1, which means that the fish caused no health problems in people who consumed whiting and red mullet caught in the southern Black Sea during the fishing seasons of 2017–2018. The carcinogenic risk index (CRI) for whiting and red mullet was also considered insignificant.

Abstract:

Chromium metal is one of the heavy metal wastes from various industries and is persistent for the agricultural environment, especially in rice fields. Chromium metal can change biodiversity and ecosystem function in paddy soil. Chromium metal phytoremediation that pollutes paddy soils with hemp (Boehmeria nivea) is important because paddy soils play a role as a living medium for food crops, especially rice (Oryza sativa). One indicator of the success of phytoremediation is the reduction of chromium metal content in the soil, so it requires a policy system to maintain a healthy environmentally friendly agriculture. This study aimed to determine the ability of Boehmeria nivea to reduce levels of chromium metal in the soil and provide policy solutions to keep environmentally healthy agriculture. This study used a complete randomized block design, random sampling of chromium metal data. The results showed the initial concentration of chromium metal in the soil was 2.36 ppm, after treatment with the interaction between Agrobacterium sp. I3 with Boehmeria nivea (P0B1T1) and interaction of organic matter (compost) with Boehmeria nivea (P0B2T1) obtained Cr 1.37 ppm metal content with a decrease of 42.01%. The resulting policy solution is the Environment Health Agriculture System (EHAS). The conclusion of this study was phytoremediation of chromium metal using Boehmeria nivea combined with the Environment Health Agriculture System can create a healthy environmentally friendly agricultural system.

Abstract:

The levels of 13 different metals (Mg, P, K, Fe, Cu, Zn, Mn, Se, Al, Cr, As, Cd and Pb) in mantle and arm tissues of Octopus vulgaris species, which were caught from Mersin Bay in winter, spring and summer seasons, were determined. The results were compared between the tissues and seasons. Potential health risks of consumption of common octopus, which is an economically important species, were evaluated with the possibility that adult and child consumers will consume common octopus 1, 3 or 5 days a week. In this context, Estimated Weekly Intake Level (EWI), non-carcinogenic Target Hazard Quotient (THQ) and Lifetime Carcinogenic Risk (CR) were determined. Pb level was found to be above the limit level determined by FAO, EU and Turkish Food Codex. EWI values were found to be below the PTWI values determined by EFSA and FAO / WHO. THQ and ∑THQ values, which are indicative of non-cancer health risks for consumers, were determined as <1. In terms of carcinogenic risk, it was determined that these values (> 10-5) for As, Cr and Cd elements pose a carcinogenic risk to the consumer, but Pb values do not pose a risk.

Abstract:

Stable blast furnace operation requires proper drainage of liquid from the hearth. The estimation of drainage rate and hearth liquid level are of utmost importance for understanding the underlying hearth phenomena. The present review gives an insight of the need for measurement of the hearth liquid level and further throws light on various methods of estimation of hearth liquid level in-depth, which is primarily divided into 2 categories namely; model-based estimation and sensor-based estimation. Although the model-based estimation and sensor-based estimation have their own advantages and disadvantages, an integrated system comprising of both methods could potentially facilitate operators to reveal the state of hearth, which is unless not available with the implementation of a single method of estimation. Furthermore, the challenges in the estimation and the prospects for determining the reliable hearth liquid level measurement in blast furnace are discussed. The article is presented to give prospect of encountering the drift occurring in estimation of liquid level, which leads to inaccurate prediction and simulation with the industrial blast furnace. Lastly, the article gives recommendation for improving the liquid level estimation methods in blast furnace.

Abstract:

The cooling system is important for the safety of blast furnace production. Measurements for over six months on a 1350 m3 blast furnace have shown that water volume distribution among the pipes in hearth is not uniform. The nature of the water volume distribution curve remains constant while furnace operation is normal, but is influenced by features of heat flux and hydrodynamic to the bustle pipe, which result in a 40–60% difference between maximum and minimum flow rates through individual pipe assemblies. A change in water volume is generally taken up by pipes that are working well. The water volume varies by 20–40% between pipes. That the problem about water non-uniform distribution of water-supplying system in cooling system is caused by the hydrodynamic pulsations existed between the parallel pipes and individual pipe. The cooling water temperature difference and water volume shows negative relationship. There may be some false positives of hearth erosion trends when the state of erosion is determined by water temperature difference for the non-uniform distribution of water volume. The inhomogeneity of the cooling intensity among the pipes merits attention.

Abstract:

The iron-carbon interfacial reaction between molten iron and carbon brick was carried out to simulate the working condition of blast furnace (BF) hearth. The carbon content in molten iron after the reaction was detected to be 5.0% which was almost saturated. XRD and SEM-EDS were conducted on the surface of polished rectangle iron before and after iron-carbon interfacial reaction. Fine striped graphite was observed in iron before iron-carbon interfacial reaction, a large amount of flake-like graphite was observed in iron after iron-carbon interfacial reaction. As a structure-sensitive physical property, the viscosity of molten iron was the macroscopic expression of its liquid structure. The liquid structure of molten iron (Fe-4.5%C, Fe-5.0%C) was measured through a high temperature X-ray diffractometer. The X-ray original diffraction intensity, the structure factor, the pair distribution function, the radial distribution function, and the main parameters of molten iron were obtained through the calculation. The presence of pre-peak in the structure factor indicated that there was a medium-range order in molten iron, some compounds or cluster of atoms might exist in molten iron, the structure model of atoms in liquid Fe-4.5%C was predicted through the structure parameters. The increase of carbon content after iron-carbon interfacial reaction was the essential reason for liquid structure evolution of molten iron in hearth.

Abstract:

Introduction. Gold- (Au-) based nanomaterials have shown promising potential in nanomedicine. The individual health status is an important determinant of the response to injury/exposure. It is, therefore, critical to evaluate exposure to Au-nanomaterials with varied preexisting health status.Objective. The goal of this research was to determine the extent of extrapulmonary translocation from healthy and inflamed lungs after pulmonary exposure to AuNPs. Male BALB/c mice received a single dose of0.8 mg·kg−1AuNPs (40 nm) by oropharyngeal aspiration 24 hours after priming with LPS (0.4 mg·kg−1) through the same route. Metal contents were analyzed in different organs by inductively coupled plasma-mass spectrometry (ICP-MS).Results. Oropharyngeal aspiration resulted in high metal concentrations in lungs (P<0.001); however, these were much lower after pretreatment with LPS (P<0.05). Significantly higher concentrations of Au were detected in heart and thymus of healthy animals, whereas higher concentrations of Au NPs were observed in spleen in LPS-primed animals.Conclusions. The distribution of AuNPs from lungs to secondary target organs depends upon the health status, indicating that targeting of distinct secondary organs in nanomedicine needs to be considered carefully under health and inflammatory conditions.

Abstract:

The erosion of the blast furnace hearth has become one of the key factors affecting the life of the blast furnace, because of the limited on-line monitoring and control means in the blast furnace hearth area, the burn-through accidents of the blast furnace hearth and bottom occur occasionally. In this work, based on the self-built platform of heat flow regulation, the control mechanism of the high melting phases of TiC is studied. The on-line control mechanism of the hearth erosion by adding titanium-containing materials was discussed. There are three steps for the on-line control of iromaking using titanium-containing materials in blast furnace. Firstly, Ti(C, N) precipitated from the molten iron due to the decrease of temperature in the erosion zone of the hearth. Secondly, the viscosity of the molten iron increased with the precipitation of Ti(C, N) in the erosional cryogenic zone and temperature further decreasing. Finally, the protective layer, included pig iron matrix and Ti(C, N) solid fulcrum, formed because of the solidification of the molten iron. The protective layer can replace the corroded lining of the blast furnace to prevent its hearth from being eroded.

Abstract:

In the agro-complex, as well as in other sectors, the use of polymeric materials is one possible way forward in the innovation and development of machines and their parts. However, machine products place high demands on the materials from which they are made. Polymeric materials are currently able to compete in certain areas where metallic material would traditionally be used; however, one of their limiting characteristic is their ability to withstand elevated temperatures. This paper describes the hardness of polymeric materials when influenced by heat, generated during the double body abrasion. The paper also describes the abrasive wear of both polymers and polymeric composite systems, as well as cast iron, used in agricultural production. Heat intensity during the two-body abrasion results in a 28% fall of the composite systems hardness, to 18% fall of the Polyamid 6 hardness and to 13% fall of the Murtfeld hardness.

Abstract:

Hot metal circulation is one of the most important factors for hearth erosion. In this article, both the production conditions reflected by production parameters and the actual erosion state are considered. A series of cases are set up to analyze the hot metal flow characteristics and its contribution to hearth erosion. The main results are as follow: (1) There are two asymmetric high-speed bands existed on both side of the taphole, which is caused by the inner shape of blast furnace hearth and will cause the erosion of blast furnace hearth. (2) The velocity inside the deadman has an obvious decrease from top to middle part and then keeps almost stable, especially at the edge of deadman. It is caused by the inhibition effect of molten iron flow around deadman, and may result in a slower update rate of deadman in the lower part as well as an increase of carbon unsaturation in the molten iron. (3) The velocity of line 4–5# around the bottom increases with the increasing of daily output, and decreases with the increasing of the depth of salamander. Therefore, in the early stage of the blast furnace campaign, a production process with high utilization factor will increase hearth erosion. (4) The inner shape of hearth and the distance between sidewall and deadman are the main factors affecting the flow rate of molten iron.

Abstract:

Alkali plays a significant role in the formation of brittle layer of carbon brick in the blast furnace hearth. The brittle layer in a commercial blast furnace hearth was investigated. Large amounts of potassium compounds were found in the brittle layer. Subsequently, the carbon bricks which reacted with potassium in the simulation of blast furnace hearth under different contents of potassium in the brick (0.25, 0.5, 1.0 and 2.0 wt.%) during various reaction times (0.5, 1, 2 and 4 h) were experimentally studied. Finally, the formation mechanism of the brittle layer in carbon brick was clarified. The investigation results show that a large number of cracks are present in the brittle layer. The average potassium content in the brittle layer is 1 wt.%. According to the experimental results, cracks in the carbon brick can be formed by the attack of potassium. The reason for the formation of the brittle layer in the carbon brick is that the liquid potassium permeates into the carbon brick through the pores and cracks, and then reacts with SiO2 and Al2O3 in CO atmosphere. The generated potassium compounds nepheline and leucite lead to the volume expansion and the damage of the carbon brick.

Abstract:

The main function of the cooling system is to help preserve the refractory lining for as long as possible, but the evaluation indicators of blast furnace cooling system have not been studied in detail. In the study, the blast furnace cooling system was analyzed in-depth from the perspective of cooling essence and heat transfer principle based on the investigation of many blast furnaces. The concept of cooling efficiency and cooling intensity of the blast furnace hearth cooling system were proposed with quantitative characterization. The results show that the cooling efficiency is 88–99% and the cooling intensity is 70–95% generally. The effect of the cooling water velocity and specific surface area on cooling efficiency and cooling intensity are analyzed from a view of optimizing the design. Improving the specific surface area of cooling system and increasing the cooling water velocity can increase the cooling efficiency and cooling intensity. The specific surface area can be designed to be more than 1.1 and the water velocity should be greater than 1.5 m/s. Finally, the blast furnace operation strategy taken in the actual production process and the methods for improving the cooling intensity and cooling efficiency are assessed.

Abstract:

The three-dimensional (3D) model of erosion state of blast furnace (BF) hearth was obtained by using 3D laser scanning method. The thickness of refractory lining can be measured anywhere and the erosion curves were extracted both in the circumferential and height directions to analyze the erosion characteristics. The results show that the most eroded positions located below 20# tuyere with an elevation of 7700 mm and below 24#–25# tuyere with an elevation of 8100 mm, the residual thickness here is only 295 mm. In the circumferential directions, the serious eroded areas located between every two tapholes while the taphole areas were protected well by the bonding material. In the height directions, the severe erosion areas located between the elevation of 7600 mm to 8200 mm. According to the calculation, the minimum depth to ensure the deadman floats in the hearth is 2581 mm, corresponding to the elevation of 7619 mm. It can be considered that during the blast furnace production process, the deadman has been sinking to the bottom of BF hearth and the erosion areas gradually formed at the root of deadman.

Abstract:

A ceramic cup is often used to prolong the hearth life of a blast furnace (BF). Corundum blocks and mullite blocks are two kinds of refractories widely used for building ceramic cups in China. Therefore, research on the corrosion resistance of these two kinds of refractories is beneficial to realize the BF longevity. In this study, the corrosion behaviours and corrosion mechanisms of molten slag and molten iron on corundum block and mullite block samples were investigated by corrosion tests. The results show that the slag corrosion resistance of corundum block was better than that of mullite block, and the corrosion mechanisms of molten slag on corundum block and mullite block were different. The aggregates fell from the matrix of the corundum sample when the matrix was corroded to a certain degree by slag, and the corrosion rate of slag on the corundum sample was controlled by the diffusive transport rate of a substance and the chemical reaction rate between slag and matrix. However, the aggregate and matrix of the mullite sample was corroded by slag at the same time, and the corrosion rate of slag on the mullite sample was controlled by the diffusive transport rate of Ca through the newly formed reaction layer. Moreover, the corundum block and mullite block had excellent iron corrosion resistance. The high temperature of molten iron led to an in situ reaction to generate a mullite phase in the corundum sample, and the high temperature affected the microstructure of the corundum block and mullite block.

Abstract:

From the results calculated by theoretical derivations, it was found that the characteristics of tuyere raceway determined by the operation condition for blast air played a critical effect on the heart activity. The speed and kinetic energy of blast air should be proportional to the volume of blast furnace (BF), and the comprehensive optimization of air volume and tuyere which should vary with the quality of raw materials was essential. The calculation methods of air volume ratio and coefficient for different BFs were put forward. Moreover, the details on hearth activity recovery of a 4747 m3 blast furnace in China were elaborated. Based on the extensive experience in blast furnace production, the various phenomena used to judge air speed and kinetic energy whether reasonable were discussed. In summary, hearth activity was closely related to the characteristics of BF raceway and reasonable air speed and kinetic energy could effectively improve the activity.

Abstract:

Background Full-depth cartilage lesions do not heal and the long-term clinical outcome is uncertain. In the symptomatic middle-aged (35-60 years) patient, treatment with metal implants has been proposed. However, the cartilage health surrounding these implants has not been thoroughly studied. Our objective was to evaluate the health of cartilage opposing and adjacent to metal resurfacing implants. Methods The medial femoral condyle was operated in 9 sheep bilaterally. A metallic resurfacing metallic implant was immediately inserted into an artificially created 7.5 mm defect while on the contralateral knee the defect was left untreated. Euthanasia was performed at 6 months. Six animals, of similar age and study duration, from a previous study were used for comparison in the evaluation of cartilage health adjacent to the implant. Cartilage damage to joint surfaces within the knee, cartilage repair of the defect, and cartilage adjacent to the implant was evaluated macroscopically and microscopically. Results Six animals available for evaluation of cartilage health within the knee showed a varying degree of cartilage damage with no statistical difference between defects treated with implants or left untreated ( P = 0.51; 95% CI −3.7 to 6.5). The cartilage adjacent to the implant (score 0-14; where 14 indicates no damage) remained healthy in these 6 animals showing promising results (averaged 10.5; range 9-11.5, SD 0.95). Cartilage defects did not heal in any case. Conclusion Treatment of a critical size focal lesion with a metal implant is a viable alternative treatment.
