The production of steel in an EAF is a batch process. Cycles, or "heats", range from about 1-1/2 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 …

Capacity (heat size) of a BOF converter ranges from 30 tons to 400 tons, but most of the converters are in the range of 100 -250 tons range. A BOF steel melting shop normally have one to three converters. The tap to tap time for a BOF heat is around 40 – 50 minutes, of which 50 % is the O2 blowing time.
