Abstract

"CHAPA DE AçO REVESTIDA COM LIGA DE ZINCO FUNDIDO E PROCESSO DE PRODUçãO DA MESMA". A presente invenção refere-se a uma folha de aço revestida com liga de zinco fundido tendo uma área da fase de liga Fe e Zn nas partes não formadas na camada de revestimento de menos de 10% da área da folha de aço como um todo e superior em resistência e conformabilidade e um método de produção desta folha de aço revestida com liga de zinco fundido por um sistema de produção contínua de revestimento de zinco que permita a produção a baixo custo sem modificação do sistema ou adição de etapas, a mencionada folha de aço revestida com liga de zinco fundido caracterizada por compreender uma folha de aço incluindo C: 0,05 a 0,40%, Si: 0,2 a 3,0%, e Mn: 0,1 a 2,5%, o saldo compreendido de Fe e as inevitáveis impurezas, tendo em sua superfície uma camada de revestimento de liga de Zn compreendida de Fe em uma concentração de 7 a 15% em peso, Al em uma concentração de 0,01 a 1 % em peso, e o saldo de Zn e das inevitáveis impurezas, a mencionada camada de revestimento contendo partículas de óxido de pelo menos um tipo de óxido selecionado entre um óxido de AI, um óxido de Si, um óxido de Mn, e um óxido complexo dos mesmos sozinhos ou em combinação.
