Resumo
THE PITCH CIRCLE DIAMETER WAS STATISTICALLY ASSESSED AGAINST A DATABASE OF OTHER STEELMAKERS IN BRAZIL AND REDUCED FROM 830MM TO 700MM. THE REPLACEMENT OF THREE-ELECTRODE ARMS WAS REQUIRED TO ACCOMPLISH THE PITCH CIRCLE IMPROVEMENT TO OPTIMIZE THE ENERGY EFFICIENCY OF THE LADLE FURNACE AND REDUCE THE WEAR OF THE LADLE SLAG LINE. ENERGY CONSUMPTION AND REDUCTION OF THE LADLE WEAR ALONG THE MOLTEN SLAG LINE ARE THE STATISTICS OF MORE THAN TWO THOUSAND HEATS, THE STABILITY OF THE ELECTRIC ARC. AFTER THE IMPLEMENTATION OF THE PITCH CIRCLE REDUCTION, THE OUTCOME ACHIEVED WAS A 10.7% INCREASE IN THE AVERAGE OF SLAG LINE LIFESPAN, ENERGY CONSUMPTION REDUCTION BY 5%, AND SAVING BY 6.8% IN THE ELECTRODE CONSUMPTION.
