Abstract

_(PROCEDIMIENTO PARA LA DESULFURACION DE MASAS FUNDIDAS DE HIERRO . CONSISTE EN AÑADIR CARBURO CALCICO Y UNA DIAMIDOCAL, ULTERIORMENTE TRATADA POR FLOTACION O CLASIFICACION NEUMATICA. LA DIAMIDOCAL ES UNA MEZCLA CONSISTENTE EN CARBONATO CALCICO Y CARBONO. PARA EL TRATAMIENTO DE ARRABIO EN CALDEROS, SE EMPLEA UNA MEZCLA QUE CONTIENE DE 30 A 70% EN PESO DE CARBURO CALCICO SIENDO EL RESTO DIAMIDOCAL. LAS MEZCLAS DE DESULFURACION, SON PREPARADAS MOLIENDO CONJUNTAMENTE CARBURO CALCICO CON LA DIAMIDOCAL ULTERIORMENTE TRATADA Y SECA EN UN MOLIDO QUE PUEDE SER TUBULAR.
