Enakievo Metallurgical Plant

During the last six years production of high-fluxed sinter at sinter workshop of Enakievo metallurgical plant is accomplished by using sinter charge, comprising almost equal shares of iron ore concentrate and metallurgical wastes. It is done because of insufficient and non-regular supplies of iron ore concentrates. The experience gained can be of some interest for specialists of sintering and BF production of other plants to ensure the operation under conditions of breach of iron ore raw material supply as well as utilization of wastes. An analytical and statistical evaluation of technical and economical indices of sintering accomplished, while component content, the charge basicity and technological conditions of it preparation and sintering variation. Results of industrial study of technological conditions and sinter production parameters presented while its basicity was varied within the range of 1.7–4.1 abs. units in some periods of 2019. Results of pilot-industrial experiments on production in the IVQ-2019 of several batches of rather strong sinter highlighted, while their basicity was varied in series from 2.0 to 5.0 abs. units. A method of adjusting of sintering speed of a high-basic charge along the width of sintering machine proposed, comprising a rational forming of the charge layer in the charging funnel and the layer profile with a concave parabola surface form along the sintering machine width. The method comprised also an increase of the charge volume density in the upper elemental layers and particularly – in the peripheral zones of general charge layer at the sintering machines pallets. Description of the charging complex on the sintering machine pallets was given. Scientific and practical recommendations elaborated for modernization the technology and technological equipment for the charge loading on the sintering machine.

Main Production

During the study of technological data of the process of liquid iron transportation, it was found that the number of locomotives and mixers depending on the duration of operations and especially on the inter-operational downtime does not always ensure normal rhythm of the main production. It leads to significant production losses, therefore, the work of the producing and transport complex is not effective enough. The authors have developed a simulation model of a logistics system for transporting liquid iron at a metallurgical plant. The study and construction of the model was performed using AnyLogic. Real data from production, namely the schedule of blast furnace smelting for a three-week period, was used as the initial data. To prove adequacy of the model, the results were compared with the actual tact of the mixers movement, as well as with the theoretical need of the converter shop. Values of the liquid iron weight delivered to the converter shop were obtained during the simulation and were related to the theoretical ones. Efficiency of the model is achieved by automatically collecting in real time of statistical values of the parameters of simulation objects. The system analyzes the collected data and makes decisions based on them for a short period of time (less than one second). In default operation mode of the simulation model, motion of the mixers is controlled automatically without participation of the dispatcher, which improves efficiency, as well as decision-making speed. Such model provides simulation of failures in operation of the converter shop. According to the simulation results, it can be concluded that the system delivers less liquid iron to a converter shop, but retains its rhythm. After resuming the operation of all converters, the tact of transportation reaches the required level.

The method for calculating indicators of blast furnace smelting with replacement of part of coke with additional fuels has been developed on the basis of full and complex compensation and compensating measures. Efficiency of the use of natural gas and pulverized coal in the blast furnace conditions of the Enakievo Metallurgical Plant was calculated and it has been confirmed as rather high. Increase in the consumption of natural gas from the baseline (71.8 m3/t of iron) to 110 m3/t ensures a corresponding increase in productivity of the blast furnace to 107.6 % and a decrease in the consumption of coke to 417.3 kg/t of iron (–38.4 kg/t, –8.42 %). Replacing natural gas with pulverized coal in the amount of 160 kg/t of iron made it possible to completely remove it from the blast. At the same time, coke consumption decreased to 354.59 kg/t of iron (–101.1 kg/t; –22.18 %). Increasing the consumption of pulverized coal fuel up to 200 kg/t of iron with compensation of the blast temperature of1200 °Cand oxygen of the blast of 25 % provides an increase in the productivity of the blast furnace to 105.8 % and reduction of coke consumption to 303.8 kg/t of iron (–151.9 kg/t, –33.33 %). High efficiency of the use of pulverized coal in conditions of the Enakievo Metallurgical Plant is explained by its lower cost compared to natural gas, high carbon content in coal and a significantly lower effecton the theoretical combustion temperature and other technological parameters.

Background: The development of cardiovascular diseases is determined not only by working conditions but also by genetic characteristics of employees. Genetic GSTM1, GSTT1 and GSTP1 variations contribute to individual differences in responses to industrial chemicals and carcinogens. Objective: To study the features of the genetic polymorphism of the GSTM1, GSTT1, and GSTP1 genes in metallurgical plant workers with diseases of the cardiovascular system in the town of Nizhny Tagil, Sverdlovsk Region, Russian Federation. Materials and methods: The case cohort included 61 men aged 33 to 61 years (mean: 48.15 ± 7.50 years), working in the converter shop and suffering from heart diseases. The control cohort consisted of 29 conditionally healthy male employees, aged 23–56, of the same iron and steel works having no signs of a cardiovascular disease. The DNA was isolated from peripheral blood using a standard technique. Deletion polymorphism of GSTM1 and GSTT1 genes was determined by quantitative PCR; Ile105Val polymorphism of the GSTP1 gene was established by qPCR using a commercial test kit. Results: We observed no statistically significant differences between the cohorts for any of the studied genes. The frequency of occurrence of the combination of GSTM1 (0/0) and GSTT1 (0/0) in the cases and controls was 14 % and 11 %, respectively, but the difference was negligible. Conclusions: Our findings demonstrate that the presence of null genotypes of GSTM1, GSTT1, as well as the mutant GSTP1 allele and the associated loss of enzyme activity contribute little to the development of cardiovascular diseases in workers exposed to occupational hazards.
