Abstract

PROCESO PARA LA FABRICACION DE LADRILLOS REFRACTARIOS. CONSISTE EN PREPARAR UNA COMPOSICION A BASE DE MAGNESIA SINTERIZADA Y DE ESPINELA DE MGO.AL2O3, CONSISTENTE EN UN 82 A UN 90% EN PESO DE MGO Y DE UN 10 A UN 18% EN PESO DE AL2O3 Y HASTA UN 3% EN PESO DE IMPUREZAS HABITUALES; EN REALIZAR EL PRENSADO DE LA COMPOSICION FORMANDO LADRILLOS; Y EN REALIZAR SEGUIDAMENTE UNA COCCION A UNA TEMPERATURA COMPRENDIDA ENTRE 1.450 Y 1.600 GRADOS, CON LO QUE SE CONSIGUE UNA RESISTENCIA AL FUEGO BAJO PRESION ADECUADA. DE APLICACION EN EL REVESTIMIENTO DE HORNOS UTILIZADOS EN LA INDUSTRIA DEL CEMENTO.
