WhatsApp: +86 18838072829The production of steel in an EAF is a batch process. Cycles, or "heats", range from about 11/2 to 5 hours to produce carbon steel and from 5 to 10 hours or more to produce alloy steel. Scrap steel is charged to begin a cycle, and alloying agents and slag materials are added for refining. Stages
