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."PROCESS FOR PRODUCING STEEL STRIP AND FUNDED STEEL STRIP PRODUCED BY THE SAME". Steel strips and processes for producing steel strips are provided. In one illustrated embodiment, a process for producing steel strip includes continuously casting molten steel into a strip, said molten steel comprising a waste concentration of 2.0% by weight or less is selected with respect to the microstructure of the strip. finished to provide a desired yield strength; and cool the strip to turn the austenite strip into ferrite in the temperature range of 850 <198> C to 400 <198> C. Cast steel with improved yield strength properties is produced by this process.
