Abstract
PROCEDIMIENTO PARA LA FABRICACION DE ACERO A PARTIR DE CHATARRA. LA CHATARRA SE DISPONE EN UN CONVERTIDOR, DONDE TIENE LUGAR UN CALENTAMIENTO PREVIO DE LA MISMA. DURANTE ESTA FASE SE HACEN TRABAJAR, COMO CALENTADORES, LAS TOBERAS DE COMBUSTIBLE Y DE OXIGENO DISPUESTAS POR DEBAJO DE LA COLADA. AL MISMO TIEMPO, POR ENCIMA DE LA COLADA SE INYECTA OXIGENO MEDIANTE DISPOSITIVOS DE SOPLADO, SIENDO INTRODUCIDO EN EL PROCESO DE AFINO ENTRE EL 20 Y EL 80 POR 100 DE LA CANTIDAD TOTAL DE OXIGENO. EL TIEMPO DE FUSION Y EL RENDIMIENTO FERMICO DEL COMBUSTIBLE SE MANTIENEN CONSTANTES, CON PEQUEÑAS FLUCTUACIONES, CONSIGUIENDOSE DE UN 10 A UN 30 POR 100 MAS DE ACERO DEL QUE SE TENGA PREVISTO. LA CANTIDAD ADICIONAL DE ACERO ES EVACUADA Y RECOGIDA EN UN CALDERO AUXILIAR PARA DESPUES SER APORTADA DE NUEVO, UNA VEZ EFECTUADA LA CARGA Y EL CALENTAMIENTO PREVIO.
