Abstract

SE PRESENTAN CRISOLES UTILIZADOS PARA PROCESOS DE REFINADO AL VACIO, POR EJEMPLO UN VOD, QUE ESTAN PROVISTOS DE TAPAS PARA CUBRIR LAS ABERTURAS DE LOS CRISOLES. LAS TAPAS GENERALMENTE CONSTAN DE MATERIALES REFRACTARIOS, QUE SE REQUIEREN QUE TENGAN UNA EXCELENTE RESISTENCIA AL DESCASCARILLAMIENTO TERMICO DEBIDO A LOS CICLOS DE CALOR Y NO INHIBEN LA DESCARBONIZACION DURANTE LOS PROCESOS DE REFINADO DEL ACERO FUNDIDO. LA TAPA DEL CRISOL COMPRENDE UN MATERIAL REFRACTARIO QUE TIENE UN CONTENIDO DE CARBONO DE UN 5% DE SU PESO O MAYOR. PREFERIBLEMENTE, UN MATERIAL REFRACTARIO TIENE UN CONTENIDO DE CARBONO DE UN 5% DE SU PESO O MAYOR Y SE UTILIZA PARA UNA SECCION CENTRAL DE LA TAPA DEL CRISOL, Y UN MATERIAL REFRACTARIO QUE TIENE UN CONTENIDO DE CARBONO INFERIOR AL 5% DE SU PESO SE UTILIZA PARA LAS SECCIONES PERIFERICAS DE LA TAPA DEL CRISOL.
