Abstract

PROCESO PARA PRODUCIR UNA BANDA DE ACERO DE ESTRUCTURA DUPLEX EN DONDE LA BANDA LAMINADA EN FRIO DE ACERO INOXIDABLE AL CROMO COMPRENDE, ADEMAS DE FE, 10,0% A 20,00% DE CR, DE UN 1,15% DE C, UN 0,12% DE N SIENDO EL (C+N) DEL 0,02% A 0,20 (POR) , UN 2,0% DE SI, UN 1,0% DE MN Y UN 0,6% DE N, SE PASA CONTINUAMENTE A TRAVES DE UNA ZONA DE CALENTAMIENTO DONDE SE CALIENTA PARA FORMAR DOS FASES DE FERRURO Y AUSTENITA Y LA BANDA CALIENTE SE ENFRIA HASTA UN INTERVALO DE ENFRIAMIENTO SUFICIENTE HASTA TRANSFORMAR LA AUSTENITA EN MARTENSITA. EL PRODUCTO TIENE UNA GRAN RESISTENCIA Y ELONGACION, REDUCIDA ANISOTROPIA PLANA Y UNA DUREZA DE AL MENOS HV 200.
