Abstract

LA PATENTE AFECTA A UN PROCESO PARA LA ADICION DE ALEADORES EN UNA COLADA METALICA, EN ESPECIAL EN COLADAS DEACERO AL PICAR UN CONVERTIDOR EN UNA CAZOLETA DE FUNDICION. EN ESTE PROCESO SE APLICAN LOS ALEADORES EN FORMA DE CHORRO AL CHORRO DE COLADA METALICA COLADA METALICA, CONFORMANDO EL CHORRO DE ALEADORES CON EL PLANO VERTICAL FORMADO POR EL CHORRO DE COLADA METALICA UN ANGULO. CARACTERISTICO DE LA PATENTE ES QUE, EN EL CASO DE UNA SITUACION VARIABLE DEL CHORRO DE COLADA METALICA COMO CONSECUENCIA DE UNA INCLINACION VARIABLE DEL CONVERTIDOR O COMO CONSECUENCIA DE UN TAMAÑO Y LONGITUD VARIABLES DE LA PIQUERA DEL CONVERTIDOR POR DESGASTE DEL MISMO Y/O EN EL CASO DE SITUACION VARIABLE DEL CHORRO DE ALEADOR COMO CONSECUENCIA DE LA COMPOSICION VARIABLE DEL ALEADOR, SE PUEDE AJUSTAR CONTINUAMENTE LA DIRECCION DEL CHORRO DE ALEADOR PARA UNA UNION DE AMBOS CHORROS.
