Abstract
PROCESO PARA DESGASIFICAR Y DESCARBONIZAR DIRIGIDO A UN PROCESO PARA LLEVAR A CABO LA DESGASIFICACION A VACIO NO DESOXIDANTE O LIGERAMENTE DESOXIDANTE DE ACERO FUNDIDO UTILIZANDO EL PROCESO RH O EL PROCESO DH. EL PROCESO INCLUYE EL SOPLADO DE O O DE UN GAS QUE CONTIENE O HACIA LA SUPERFICIE DEL ACERO FUNDIDO EN UNA CAMARA DE VACIO PARA PROMOVER LA REACCION DE DESCARBONIZACION. EL PROCESO ADEMAS INCLUYE UNA ETAPA DE COMBUSTION DEL CO EN LA VECINDAD DE LA SUPERFICIE DEL METAL FUNDIDO CON CONTROL DEL TIEMPO, EN EL QUE LA CONCENTRACION DE (CO + CO2) EN UN GAS DE SALIDA ES MAS ALTA O IGUAL A 5% Y CON UNA PROPORCION DE CO2 FRENTE A (CO + CO2) EN EL GAS DE SALIDA APROXIMADAMENTE DEL 30%. EL CALOR GENERADO EN LA COMBUSTION DEL CO SE UTILIZA PARA COMPENSAR LA CAIDA DE TEMPERATURA DEL ACERO FUNDIDO.
