Abstract

"PROCESSO PARA PRODUZIR TIRA DE AçO E TIRA DE AçO FUNDIDO PREPARADA POR ESSE PROCESSO". Uma tira de aço carbono plana (12) é fundida continuamente em um fundidor de cilindros gêmeos (11) e passa para uma mesa de saída (17) na qual é submetida a resfriamento acelerado por meio de cabeçotes de resfriamento (18) pelo que a mesma é resfriada para transformar a tira de austenita em ferrita numa faixa de temperatura entre 850<198>C e 400<198>C sob uma velocidade de resfriamento de não menos do que 90<198>C/segundo, de maneira tal que a tira é dotada de um limite de elasticidade maior do que 450MPa. Depois da fundição e antes do resfriamento, faz-se passar a tira através de um laminador a quente para se reduzir a espessura da tira em pelo menos 15% e até 50%.
