Abstract

OBJETIVO: PARA EVITAR (1) LO PROBLEMAS OCURRIDOS EN EL MOMENTO DE GOLPEAR LOS REBORDES POR LOS LAMINADORES, (2) EL DESGASTE DE LAS SUPERFICIES LATERALES DE LOS LAMINADORES HORIZONTALES DE UN TIPO DE ANCHO FIJO ASI COMO LA NECESIDAD DE UN CAMBIO DE LAMINADORES FRECUENTE, (3) EL DESGASTE DE LAS SUPERFICIES LATERALES DE LOS LAMINADORES DE TIPO DE ANCHO FIJO, Y (4) LA FORMACION DE GRIETAS DE LAMINADO EN LAS SUPERFICIES INTERIORES DE LOS REBORDES DURANTE EL LAMINADO EN SERIE A TRAVES DE UN MONTAJE DE LAMINADORES DE UR+E+UF. CONSTITUCION: SE LLEVA A CABO UN LAMINADO TRASERO CON TREN DE LAMINADO UR QUE TIENE UNA ANCHO W{SUB,R} DE LAMINADORES HORIZONTALES, UN TREN DE LAMINADO UF QUE TIENE UN ANCHO W{SUB,F}DE LAMINADORES HORIZONTALES, Y UN TREN DE LAMINADO E QUE TIENE UN ANCHO W{SUB,E} DE LAMINADORES HORIZONTALES CON LAS SIGUIENTES CONDICIONES: W{SUB,F}>W{SUB,E}, W{SUB,R}, O W{SUB,E}<W{SUB,F}, W{SUB,R}.OBJECTIVE: TO AVOID (1) THE PROBLEMS OCCURRED AT THE TIME OF BEAMING THE FLASHES BY THE LAMINATORS, (2) THE WEAR OF THE SIDE SURFACES OF THE HORIZONTAL ROLLERS OF A FIXED WIDTH TYPE AS WELL AS THE NEED FOR A CHANGE , (3) THE WEAR OF THE SIDE SURFACES OF THE FIXED WIDTH TYPE ROLLERS, AND (4) THE FORMATION OF ROLLING CRACKS IN THE INTERIOR SURFACES OF THE Flanges DURING THE SERIAL ROLLING THROUGH A MOUNTING OF UR ROLLERS + E + UF. CONSTITUTION: A REAR LAMINATE WITH UR LAMINATED TRAIN THAT HAS A W {SUB, R} WIDTH OF HORIZONTAL ROLLERS, A UF ROLLED TRAIN THAT HAS A W {SUB, F} WIDTH OF LAMINATORS, AND A TRAIN OF LAMINATE E THAT HAS A W (SUB, E} WIDTH OF HORIZONTAL LAMINATORS WITH THE FOLLOWING CONDITIONS: W {SUB, F}> W {SUB, E}, W {SUB, R}, OW {SUB, E} <W {SUB, F}, W {SUB, R}.
