Abstract
GUNNING REFRACTORY SCRAP FROM RH DEGASSER AND TUNDISH ARE MGO RICH SOURCES AND DESPITE THIS FACT, THESE SCRAPS ARE DESTINATED TO LANDFILL. FOR ENVIRONMENTAL IMPACT AND COST REDUCTIONS, THE SPENT REFRACTORIES WERE TESTED AT BOF AS SLAG CONDITIONER, REPLACING RAW DOLOMITE. SPENT REFRACTORY WAS COLLECTED AT SCRAP BOX AND BAGS AND ADDED TO BOF TO CONDITIONING SLAG ACCORDING OPERATIONAL NECESSITIES. AFTER CHEMICAL COMPOSITION SCRAP ANALYSIS AND TRIAL ON BOF WITH VISUAL INSPECTION, GUNNING SCRAPS WERE EVALUATED AS SUITABLE TO REPLACE RAW DOLOMITE AS SLAG CONDITIONER. ALSO, RESIDUES THAT WOULD BE SEND TO LANDFILL WERE USED AS A BYPRODUCT, REDUCING CO2 EMISSIONS ON TRANSPORT AND REDUCING CONSUMPTION OF NO-RENEWABLE SOURCES
