Abstract

METODO DE TRATAMIENTO DE METALES Y ALEACIONES FERROSAS. CONSISTE EN INTRODUCIR EN UN BAÑO LIQUIDO DEL METAL O DE LA ALEACION A TRATAR UN HILO FORRADO CONSTITUIDO POR UNA ENVOLVENTE METALICA TUBULAR ALARGADA EN CUYO INTERIOR SE HALLA EL ALMA QUE CONSTA DE UNA ALEACION QUE TIENE AL MENOS 75% DE CALCIO Y AL MENOS UNO DE LOS METALES NIQUEL Y LLUMINIO, A UNA TEMPERATURA COMPRENDIDA ENTRE 1.625JC Y 1.660JC; HACER AVANZAR DICHO HILO A TRAVES DEL BAÑO DE 60 A 105 M/MINUTO; Y PROSEGUIR EL AVANCE DEL HILO HASTA LA INTRODUCCION EN EL BAÑO DE 125 A 600 G DE CALCIO POR TONELADA DE BAÑO. TIENE APLICACIONES PARA EL TRATAMIENTO DEL ACERO LIQUIDO CON OBJETO DE EVITAR LA OBTURACION DE LOS TUBOS DE COLADA.
