Calculations of Material and Heat Balance of Low-Carbon Ferrochromium Melt With The Use of Complex Reducing Agent

Abstract

Calculations of material and heat balance of melt of low-carbon ferrochromium FeChS48 (with content of phosphorus lower than 0.015 %) and complex reducing agent (silicon and aluminium) are carried out.

At the 1:1 ratio of aluminium complex reducing agent and FeChS48 the metal is obtained with phosphorus content lower than 0.015 %. As a result of heat balance calculations it is established that the use of complex reducing agent leads to 23 % decrease of electricity consumption.
