Abstract

LA ESPECIFICACION MUESTRA UN PROCESO PARA LA PRODUCCION DE UNA FERROALEACION EN UN RECIPIENTE DE FUNDIDO. SE INYECTA UN MATERIAL QUE CONTENGA UN METAL DE ALEACION EN UN BAÑO DE FUNDICION CONTENIDO EN EL RECIPIENTE. TAMBIEN SE INYECTAN EN EL RECIPIENTE UN FLUJO, UN MATERIAL CARBONOSO Y UN GAS QUE CONTENGA OXIGENO. SE CONTROLAN LAS PROPORCIONES DE INYECCION DE LOS DISTINTOS COMPONENTES PARA CONSEGUIR EL CONTROL DEL AMBIENTE DE OXIDACION Y REDUCCION DENTRO DEL RECIPIENTE CONSISTENTE CON UN RITMO RAPIDO DE INYECCION. EL MATERIAL QUE CONTIENE EL METAL DE ALEACION O SE REDUCE E INCORPORA EN LA FASE METALICA O SE OXIDA E INCORPORA EN LA ESCORIA. LOS GASES DE LA COMBUSTION POR ENCIMA DEL BAÑO DE FUNDICION SE OXIDAN PARA PROPORCIONAR MAS CALOR AL PROCESO. EL METAL DE ALEACION O ESCORIA QUE CONTIENE EL METAL DE ALEACION SE RECUPERA COMO PRODUCTO. EL PROCESO ES APLICABLE A LA PRODUCCION DE FERROALEACIONES TALES COMO FERROCROMO, FERROMANGANESO, FERRONIQUEL Y FERROVANADIO.
