The subject of the invention is a method of production of low-carbon ferrosilicochrome in electric arc-resistance furnaces. Ferrosilicochrome is used as a reducing agent in low-carbon ferrochrome production processes as well as an alloy and deoxidation additive for production of chromium steels.
The object of invention is to reduce carbon content in ferrosilicochrome and to conduct a two-phase process of obtaining low-carbon ferrosilicochrome in electric arc furnaces and a refining ladle without additional costs of charge materials and with the use of bath heat in the refining ladle.
The solution allows to:
