Abstract
"PROCESSO PARA DECAPAR DE MODO CONTìNUO TIRA DE AçO ELéTRICO E PROCESSO PARA DECAPAR TIRA DE AçO ELéTRICO". O processo de decapagem da presente invenção é destinado a decapar tira de aço elétrico de maneira contínua e compreende pelo menos um tanque de decapagem equipado com pelo menos um conjunto de borrifadores destinados a borrifar as superfícies superior e inferior de uma tira de aço com uma solução compreendida de peróxido de hidrogênio antes e/ou após a tira ser imersa em uma solução contida em um tanque de decapagem. O(s) conjunto(s) de borrifadores em cada um dos tanques de decapagem é(são) localizado(s) acima do nível da solução do banho de decapagem, ao invés de ser(em) localizado(s) em tanques de borrifo separados. Ao sair do banque de decapagem final a tira é escovada/limpa para soltar qualquer escama residual para formar uma tira limpa.
