Abstract

Procedimiento de tratamiento continuo de chapas de acero, en el que se somete la chapa a un calentamiento y a un enfriamiento, y en el curso de al menos una de las fases del cual se produce sobre la chapa una capa de óxido, caracterizado por el hecho de que se pone dicha chapa en contacto con una solución de al menos un ácido orgánico cuyo pH se mantiene entre un valor mínimo de 1,5 y un valor máximo de 4, y cuya temperatura se mantiene por encima de un valor mínimo Tm dado por la fórmula: Tm = 20 + (pH - 1,5) x 32, en la que pH es el valor al que se mantiene el pH de la solución de decapado, y por el hecho de que dicha solución contiene hierro en cantidad superior a 50 mg por litro.
