发明名称 PROCESS FOR THE PRODUCTION OF CRUDE IRON FOR FOUNDRY CASTING
摘要 The process comprising supplying an electric arc furnace with ferrous products and fluxes so as to form a bath of metal and slag and adding carbon to the bath of metal. The ferrous products are pre-reduced ores which are continuously introduced into the furnace between the electrodes of the furnace in the course of the formation of the bath. A carburizing agent is introduced to bring the carbon content of the bath to a value between 1.7 and 6.7%. Thereafter, the slag is removed. If desired, the carbon content of the cast iron can be brought to the desired value by adding further carburizing agent. The cast iron is then poured from the furnace.
