Protsenko O. Increasing ecological safety during production of ferrosilicon by means of electroslag remelting method

The research object is the ecologically dangerous technological processes of ferrosilicium production by means of electroslag remelting and their impact on natural environment and a human being. The aim is to decrease a negative impact of ferrosilicium production by means of electroslag remelting on environment through both the improvement of activities to reduce power-gas emission and wastes recycling. The research methods are mathematical statistics, full-scale observation, mathematical modeling, analysis, generalization of scientific and technical information. The theoretical and practical results are as follows: the features of ecological danger formation in the conditions of an technogenic impact of enterprises that produces ferrosilicium by means of electroslag remelting on the environment components are determined. The complex of technological and logistical activities to improve the ecological safety of production is scientifically substantiated and implemented. The novelty of research is as follows: the new composition of charge materials, which enables to recycle dust wastes in production, is first substantiated; the strategy to improve ecological safety of ferrosilicium production, which enables to reduce the atmospheric emission of pollutants and contaminants to meet the standards, is developed; the technology of the briquetting of small fractional waste products in ferrocilicium smelting is improved; scientific ideas about the complex ecological estimation of environment pollution in ferrocilicium production by the method of electroslag remelting are advanced; the scientific school to estimate a risk for people's health is advanced. The incorporation of research results is as follows: Stakhanov production shop of the limited partnership EKINA has incorporated the complex of technological and logistical activities in ferrocilicium production in direct current kilns; the limited partnership KONKRET has introduced the advanced technology of the briquetting of small fractional waste products in ferrocilicium production. The field of application: the results of research can be used in the enterprises of ferroalloy production.
