Abstract
LA PRESENTE INVENCION SE REFIERE A UN METODO DE REFINADO DE ACERO FUNDIDO PARA REFINAR ACERO FUNDIDO, EL CONTENIDO DE CARBONO DEL CUAL NO ES SUPERIOR AL 0,1% DE PESO, MEDIANTE SOPLADO DE GAS DE OXIGENO PARA DESCARBURACION A UNA VELOCIDAD DE SOPLADO DE FORMA QUE UNA CAVIDAD, LA PROFUNDIDAD DE LA CUAL ES DE 150 A 400 MM, PUEDA FORMARSE EN LA SUPERFICIE DEL ACERO FUNDIDO EN UN APARATO DE REFINADO AL VACIO DE TIPO BARRIL RECTO EN EL QUE ESTAN DISPUESTOS UN RECIPIENTE DE VACIO DE TIPO DE BARRIL RECTO QUE NO TIENE FONDO DE RECIPIENTE Y UN CALDERO. CUANDO ES NECESARIO, EL PROCESAMIENTO DE DESCARBURACION ANTERIOR REALIZADO POR SOPLADO DE GAS DE OXIGENO ES COMBINADO CON: UN PROCEDIMIENTO DE CALENTAMIENTO DE AL EN EL QUE AL AÑADIDO AL RECIPIENTE DE VACIO ES QUEMADO POR GAS DE OXIGENO SOPLADO EN EL RECIPIENTE DE VACIO A UNA VELOCIDAD DE SOPLADO TAL QUE LA PROFUNDIDAD DE CAVIDAD PUEDE SER DE 50 A 400 MM; UN TRATAMIENTO DE DEGASIFICACION REALIZADO EN UNA CONDICION DE VACIO ALTA; UN TRATAMIENTO DE DESULFURACION EN EL QUE UN AGENTE DE DESULFURACION ES SOPLADO EN EL RECIPIENTE DE VACIO; O UN TRATAMIENTO DE CALENTAMIENTO DE QUEMADOR EN EL QUE UN AGENTE MEJORADOR DE COMBUSTION ES SOPLADO JUNTO CON EL GAS DE OXIGENO, EN DONDE CADA TRATAMIENTO EXCEPTO EL TRATAMIENTO DE DEGASIFICACION DE VACIO ALTO ES REALIZADO EN UN GRADO DE VACIO DE 100 A 400 TORR.
