Abstract

CON EL FIN DE CREAR UN PROCEDIMIENTO PARA ENDEREZAR PERFILES DE ACERO LAMINADOS QUE SIN EL GASTO DE APARATOS DE LOS DISPOSITIVOS DE ENDEREZADO CONOCIDOS SUMINISTRE UN PERFIL DE ACERO DE ALTA CALIDAD Y BAJO EN TENSIONES PROPIAS, SE PROPONE CONFORME A LA INVENCION QUE UN PERFIL DE ACERO CUYA TEMPERATURA MAXIMA LOCAL EN LA SECCION ESTE POR DEBAJO DE A R1 Y CUYA TE MPERATURA MINIMA LOCAL DE LA SECCION ESTE POR ENCIMA DE UNA TEMPERATURA LIMITE INFERIOR PH U , SE EMPOTRE EN PARTICULAR POR SUS EXTREMOS Y A CONTINUACION SE ENFRIE, DONDE YA LA TEMPERATURA LIMITE INFERIOR PH U PROVOCA UNA DILATACION TER MICA EN TODAS LAS FIBRAS DEL PERFIL DE ACERO DEBIDO AL EMPOTRAMIENTO, QUE ES SUPERIOR A LA DILATACION QUE SERIA NECESARIA PARA LA PLASTIFICACION DE LAS FIBRAS QUE SUFRIRIAN LAS TENSIONES PROPIAS DE COMPRESION MAYORES EN EL CASO DE QUE EL PERFIL DE ACERO NO ESTUVIERA EMPOTRADO Y SE ENFRIARA SIMPLEMENTE AL AIRE.
