Steel in Translation Aims and scope

Abstract

This article analyzes smelting parameters of mass scale ferroalloys upon increase in furnace capacity on the basis of domestic and foreign data. It has been demonstrated that upon increase in the power of furnace transformers, the energotechnological parameters of furnaces operating by slagging and non-slagging carbothermic process are impaired. In addition, increase in the power of furnace transformers does not result in adequate increase in the furnace efficiency, since this is not equivalent to the expected increase in active power in the bath of ferroalloy furnace, which is unfavorable for the efficiency. The methods of increase in the operation efficiency of ferroalloy electric furnaces are considered.
