Abstract

OPERATION CONDITIONS AT BRAZILIAN BOF FACILITIES ARE CHANGING DUE TO REFINEMENT NECESSITY, RAW MATERIAL COST OR INCREASE OF OUTPUT. AS A RESULT, BOF REFRACTORY LINING WEAR AT MOST OF THE STEELMAKING PLANTS IS INCREASED. THE NEED TO INCREASE PRODUCTION IMPLIES INCREASING THE AVAILABILITY OF THE ASSET. THIS LEADS TO A NEW APPROACH REGARDING REFRACTORIES MATERIALS, DESIGN AND REPAIR PROCEDURES TO REDUCE THE WEAR VELOCITY. IN THIS ARTICLE WE WILL DISCUSS THE REPAIR PROCEDURES AND TECHNIQUES TO MITIGATE THE WEAR RATE.
