ABSTRACT:
In a process of manufacturing an alloy steel, particularly stainless steel, in an electric arc furnace, in a first stage the furnace charge is brought to a molten state, in a second stage ferro-alloy in divided form is continuously supplied to the molten charge and simultaneously a refining fluid is blown into the charge, and in a third stage the molten charge is decarburized, if necessary, to give the required carbon content, and chromium oxide in the slag is reduced.
