Chromium-alloyed steel prodn - with additional reduction of metal oxides in the slag

摘要

Production of steel with the use of pre-improved chrome ore pellets in an electric furnace is improved by applying additional reduction of the residual metal oxides in the slag with a metallic, Si-contng. reducing agent. The reduction is carried out in the furnace or pref. in the ladle. By this method, Cr and other metals remaining in considerable amts. in the primary slag can be recovered.
