Abstract

EL LIMITE ELASTICO DE UNA SECCION DE ACERO ENROLLADA EN FRIO SE AUMENTA Y CONTROLA MEDIANTE LA REALIZACION DE UNA CANTIDAD PREDETERMINADA DE DEFORMACION MEDIANTE UNA OPERACION EN FRIO EN UN PROCESO DE FORMACION DE RODILLO EN LINEA SEGUIDO DE UNA CANTIDAD CONTROLADA DE DESGASTE DE DEFORMACION EN DONDE LA TEMPERATURA DE LA SECCION DE ACERO ES ELEVADA A UN PUNTO POR DEBAJO DE 500 (GRADOS) C Y MANTENIDA A UNA TEMPERATURA ELEVADA DURANTE UN TIEMPO HASTA 30 SEGUNDOS. EL CALENTAMIENTO TIENE LUGAR TIPICAMENTE MEDIANTE CALENTADORES DE INDUCCION (16) Y EL DESGASTE DE TIEMPO PUEDE SER PROVISTO EN UN BAÑO DE GALVANIZACION EN LINEA (17) ANTES DEL ENFRIAMIENTO DEL ACERO EN UN BAÑO DE ENFRIAMIENTO (18). EL EFECTO ES MEJORADO ADEMAS MEDIANTE OTRA OPERACION EN FRIO Y LA DEFORMACION ADICIONAL CONSECUENTE EN FORMACION DE RODILLOS (19). PARA UNA COMPOSICION DE ACERO DADA EL GRADO DE MEJORA DE ELASTICIDAD PUEDE SER CONTROLADO POR LOS PARAMETROS DE TEMPERATURA Y TIEMPO Y TAMBIEN POR EL GRADO DE FORMACION DE RODILLOS INICIAL EN FORMACION DE RODILLOS (10).
