Abstract
An analysis of the energy-technological parameters of ferroalloy smelting is presented in the context of enlarging furnaces and increasing the power of furnace transformers with the aim of identifying factors that enhance operational efficiency. The increase in furnace power is characterized by a rise in the ratio of electrode current to working voltage, which consequently leads to a decrease in the active resistance of the bath in a ferroalloy electric furnace. This results in an increase in the electrical losses of the furnace. Consequently, the gap between the power of the transformers and the active power in the furnace bath widens, adversely affecting productivity. Options for technical solutions to improve the efficiency of ferroalloy electric furnaces are considered.
期刊介绍：
Steel in Translation is a journal that represents a selection of translated articles from two Russian metallurgical journals: Stal’ and Izvestiya Vysshikh Uchebnykh Zavedenii. Chernaya Metallurgiya . Steel in Translation covers new developments in blast furnaces, steelmaking, rolled products, tubes, and metal manufacturing as well as unconventional methods of metallurgy and conservation of resources. Papers in materials science and relevant commercial applications make up a considerable portion of the journal’s contents. There is an emphasis on metal quality and cost effectiveness of metal production and treatment.
