Abstract

BOCAL DE DESCARGA PARA METAL EM FUSãO EM UM VASO DE METAL EM FUSãO, APARELHOS DE SUBSTITUIçãO DE LUVA, E, MéTODO PARA OPERAçãO DE UM CONVERTEDOR é descrito um bocal de descarga para um metal em fusão para um convertedor e outros, particularmente um bocal de descarga para o metal em fusão que usa um refratário tipo luva, capaz de reduzir o tempo de descarregamento médio de forma a aumentar a eficiência operacional do convertedor e outros. O bocal de descarga compreende uma luva superior (32) montada no revestimento refratário do convertedor e uma luva inferior (33) unida destacavelmente na parte da extremidade inferior da luva superior. A área seccional transversal do furo interno da luva inferior (33) obtida depois do uso é ajustada em 60 a 98% da área seccional transversal do seu furo interno obtido na sua troca.METAL DISCHARGE NOZZLE IN A MELTED METAL VASE, GLOVE REPLACEMENT APPARATUS, AND METHOD FOR OPERATING A CONVERTER METHOD A melt metal discharge nozzle for a converter and others is described, particularly a metal nozzle. discharge to the molten metal that uses a glove type refractory, capable of reducing the average discharge time to increase the operating efficiency of the converter and others. The discharge nozzle comprises an upper sleeve (32) mounted on the converter refractory lining and a lower sleeve (33) detachably joined to the lower end portion of the upper sleeve. The transverse sectional area of the inner bore of the lower sleeve 33 obtained after use is adjusted to 60 to 98% of the transverse sectional area of its inner bore obtained in its exchange.
