Abstract

"MéTODO PARA FABRICAçãO DE TIRAS E LINHA DELAMINAçãO". A invenção refere-se a um método para afabricação de tiras de aço inoxidável, compreendendo laminação afrio de uma tira que no processo precedente foi fabricada atravésde fundição de uma corrida para formar uma tira fundida e/ou foilaminada a quente. A laminação a frio é realizada em uma linha delaminação (B), que compreende, na parte inicial da linha, pelomenos dois laminadores a frio iniciais (11-13) em série, após osreferidos laminadores a frio iniciais pelo menos um forno derecozimento (18) e pelo menos uma seção de desoxidação (26, 27)e em uma parte de terminação da linha, pelo menos mais umlaminador a frio (32). O relatório descritivo da patente revela váriosmodos de operação, incluindo passar a tira uma ou duas vezesatravés da linha.
