At the Fuji Iron Works of Japan Iron Mfg. Co., Ltd. (Nippon Seitetu K. K. Fuji Seikosyo), a steel making by means of the cold-pig-ore process (85∿90% pig) has been practised as a normal working, with the fixed basic open hearth furnace since January 1941. The purport of the present process consists in preparing the suitable raw material and overflowing naturally the first superfluous slag by utilizing the expansion of slag during the melting period. According to the present process and the like informed so far, it is not only possible to reduce the slag quantity remained in the furnace and the total quantity of slag formed, but also to oxidise and eliminate most of impurities in the raw material before the melting down period. In this manner, the purpose of the reaction of preliminary purification was almost attained, and so the operation of steel making by the cold pig ore process facilitated the more.
