Abstract

FABRICACION DE METALES MEDIANTE LA MEDICION DEL CONTENIDO DE GAS EN EL METAL FUNDIDO UTILIZANDO UN SISTEMA DE MEDICION QUE COMPRENDE UN ANALIZADOR Y UNA SONDA. EL METODO CONSISTE: 1) INSERTAR EN EL METAL FUNDIDO EL CUERPO DE UNA SONDA QUE SEA DE: MATERIAL PERMEABLE AL GAS TRANSPORTADOR (QUE CONTIENE CO COMO GAS REDUCTOR), IMPERMEABLE AL METAL LIQUIDO, DE SUFICIENTE RESISTENCIA AL CALOR PARA RESISTIR LA INMERSION AL METAL FUNDIDO, Y QUE CONTENGA CARBON; 2) DETERMINACION DEL CONTENIDO DE GAS CON UN ANALIZADOR QUE COMPARA LA MEZCLA DE GAS ARRASTRADO Y GAS TRANSPORTADOR DE SALIDA CON UN VALOR DE REFERENCIA; 3) CONTROLAR EL PROCESO BASADO EN EL VALOR DEL CONTENIDO DE GAS; LA SONDA TIENE UNA ENTRADA Y SALIDA QUE ESTAN ESPACIADAS ENTRE SI DE MANERA QUE EL GAS TRANSPORTADOR ATRAVIESA UNA PARTE SUSTANCIAL DEL CUERPO INTERIOR DE LA SONDA PARA EL ARRASTRE DEL GAS. LA INVENCION PERMITE MEJORAR LA DUCTILIDAD Y LA CAPACIDAD DE RECOCIDO DEL METAL
