PROCESS FOR USING SLAG IN STAINLESS STEEL PRODUCTION IN THE ELECTRIC ARC FURNACE

摘要

A method of forming a foamed slag on a stainless steel melt in an electric furnace involves introducing, into the slag, a powder containing metal oxide and carbon which react to form bubbles of the reduced metal vapour and carbon monoxide and thus create a stable foam. The metal oxide is an oxide of a volatile metal, especially zinc or lead, and at least part of the powder is dust from an electric steel making furnace.
