Abstract

PROCEDIMIENTO DE PREPARACION DE UNA COMPOSICION PARA MOLDES Y MACHOS DE FUNDICION DE METALES. SE AMASA DURANTE 2 MINUTOS ARENA Y UN AGENTE PARA EL VACIADO DE LA ARENA DE LOS MACHOS, TAL COMO UN DERIVADO MINERAL METALICO DEL GRUPO DE LOS ALCALINOTERREOS, EN FORMA DE POLVO FINO, Y ENTRE 1 Y 99% DE UNA ALUMINA HIDRATADA DE GRANULOMETRIA MEDIA COMPRENDIDA ENTRE 0,2 Y 5 MICROMETROS.SE AMASA DURANTE 2 MINUTOS LA MEZCLA RESULTANTE CON UN AGENTE ENDURECEDOR O SE LE SOMETE A LA ACCION DE GAS CARBONICO DURANTE 10 SEGUNDOS. SE AMASA DURANTE 2 MINUTOS LA MEZCLA OBTENIDA CON UN AGLOMERANTE A BASE DE UN SILICATO ALCALINO, SIENDO LA TEMPERATURA A LA QUE SE REALIZAN LOS AMASADOS DE 18 A 20 C Y SIENDO LA PROPORCION FINAL DE 90 A 98% EN PESO DE ARENA, 2 A 10% EN PESO DE SILICATO ALCALINO, 0,5 A 5% EN PESO DE ALUMINA Y DE 0,5 A 5% EN PESO DE AGENTE PARA EL VACIADO DE LA ARENA DE LOS MACHOS.
