Abstract

LA TENDENCIA EN LOS DIAS ACTUALES HACIA LA PRODUCCION DE ACEROS EXTRA-PUROS HA CONDUCIDO A INICIATIVAS PARA DESARROLLAR TRATAMIENTOS QUE EXTRAIGAN LOS ELEMENTOS INDESEABLES (ESPECIALMENTE AZUFRE Y FOSFORO) DEL METAL FUNDIDO ANTES DE ESTE SEA ALIMENTADO EN EL CONVERTIDOR. UNA PRACTICA EFECTIVA QUE HA SIDO DESARROLLADA Y PROBADA POR ALGUNOS DE LOS INVENTORES ANTES MENCIONADOS SE REFIERE AL TRATAMIENTO CONTINUO DEL METAL FUNDIDO MIENTRAS FLUYE A TRAVES DE LA TOLVA DEL ALTO HORNO; ESTO REQUIERE UNA OBSERVACION CONTINUA DE LA COMPOSICION DEL METAL FUNDIDO, Y EN PARTICULAR DEL CONTENIDO DE SILICONA QUE TIENE UNA FUERTE INFLUENCIA EN LA REACCION DE DEFOSFORACION. LA CELDA ELECTROQUIMICA MEJORADA DE ACUERDO CON ESTA INVENCION PERMITE MEDIR, EN UNA BASE CONTINUA Y PARA PERIODOS DE TIEMPO EXTENSOS, EL CONTENIDO DE SILICONA DEL METAL FUNDIDO DE SALIDA Y POR TANTO POSIBILITA AL OPERADOR QUE APLIQUE INMEDIATAMENTE LA ACCION CORRECTORA NECESARIA PARA PREVENIR LA DESVIACION INDESEABLE DEL CONTENIDO EN IMPUREZAS.
