Abstract
It is proposed to equip the electric arc furnaces with shaft heating of scrap that operate with continuous scrap melting in a liquid metal with powerful gas-oxygen burner units. When scrap is heated to 800°C at a gas flow rate of 15.5 m3/t and a bath is blown by oxygen at the slag-metal boundary, fuel-arc steelmaking units can successfully compete with the best modern electric arc furnaces in capacity and have ecological advantages.
