Abstract

"PROCESSO PARA PRODUZIR TIRA DE AçO E TIRA DE AçO FUNDIDA PRODUZIDA PELO MESMO". Proporcionam-se tiras de aço e processos para produzir tiras de aço. Em uma concretização ilustrada, um processo para produzir tiras de aço inclui fundir continuamente aço fundido em uma tira, o dito aço fundido compreendendo uma concentração de resíduos de 2,0%, em peso, ou menos, é selecionado com relação à microestrutura da tira acabada para proporcionar um limite de elasticidade desejado; e resfriar a tira para transformar a tira de austenita em ferrita na faixa de temperatura de 850<198>C a 400<198>C. Aço fundido com propriedades de limite de elasticidade aperfeiçoadas é produzido por meio desse processo.
