Abstract

PROCESO DE FABRICACION DE UNA TABLA BIMETALICA EN ACERO PARA RODILLO DE LAMINACION EN CONTINUO. CONSISTE EN REALIZAR UN TUBO COMPUESTO CONSTITUIDO POR UNA CAPA EXTERNA DE ACERO INOXIDABLE AL CROMO CON UNA ESTRUCTURA MARTENSITICA REVENIDA Y POR UNA CAPA INTERNA DE ACERO ESPECIAL ALEADO DE BAJO CONTENIDO EN CARBONO DEL TIPO MANGANESO-MOLIBDENO-NIOBIO. DESPUES EL TUBO ES SOMETIDO AL TRATAMIENTO TERMICO SIGUIENTE. A) AUMENTO DE LA TEMPERATURA HASTA 1.050GC, B) SALIDA AL AIRE EN CALMA, C) ENFRIAMIENTO IGUAL AL AIRE EN CALMA, Y D) REVENIDO DE DOS A CUATRO HORAS A UNA TEMPERATURA COMPRENDIDA ENTRE 600 Y 650º C. EL TUBO SE REALIZA MEDIANTE DOS COLADAS CENTRIFUGAS SUCESIVAS.
