Abstract

Patente de Invenção: <B>"MéTODO PARA GALVANIZAçãO E RECOZIMENTO APóS GALVANIZAçãO EMPREGANDO UM BANHO DE ZINCO E ALUMìNIO"<D>. A presente aplicação descreve um método para galvanização e recozimento após galvanização por imersão a quente que emprega um banho de zinco e alumínio. As tiras são imersas no banho para produzir tiras recozido após galvanização e galvanizadas substancialmente livres de borra. O banho pode ter substancialmente a mesma concentração de alumínio efetivo tanto durante o galvanização quanto durante a galvanização, e a temperatura de ponto de referência do banho está a uma temperatura de cerca de 440°C até cerca de 450°C. A temperatura da tira na tromba é controlada entre 470°C e 538°C, dependendo da composição do aço.
