Abstract

PARA LA SUPRESION DE POLVO Y HUMO DURANTE LA FABRICACION DE ACERO ELECTRICO EN UN HORNO ELECTRICO DE FUSION, AL FUNDIRSE PRODUCTOS DE HIERRO, COMO HIERRO BRUTO, CHATARRA DE HIERRO, COMPRIMIDOS SINTERIZADOS DE HIERRO REDUCIDOS DIRECTAMENTE Y DIVERSOS METALES DE ALEACION O SUS MEZCLAS CON IMPUREZAS ALTAMENTE FLUCTUANTES, SE CONDUCE CO2 SOLIDO AL RECEPTACULO DE FUSION, POCO ANTES, DURANTE O DESPUES DE LA CARGA. CON ELLO SE EVITA LA COMBUSTION EN FORMA EXPLOSIVA DE LAS MATERIAS COMBUSTIBLES, EN EL QUE EL OXIGENO ES DESPLAZADO DURANTE EL PROCESO DE LA CARGA DEBIDO A LA OBTENCION DE CO2 GASEOSO QUE SE EXPANDE.
