Abstract
"MéTODO PARA A PRODUçãO DE AçO PARA MOLDES GRANDES". A presente invenção trata de um método para a produção de aço para moldes grandes. De acordo com a invenção, esta aço é obtido ao ser fundido em um forno elétrico seguido por uma segunda operação metalúrgica em aquecimento em panela de fundição, sendo que esta operação é seguida por uma degaseificação sob vácuo a menos de 1 torr, na verdade, 0,2 torrs de uma mistura que tem a seguinte composição: Manganês 1 a 3%, Silício <0,400%, Fósforo <0,015%, Cromo 1,50 a 3,5%, Molibdênio 0,25 a 1%, Nióbio 0,100 a 0,250%, 100 a 300 ppm de Titânio ou zircónio se necessário, Cobre <243>0,300%, Níquel <243>0,300%, Nitrogênio <243>80 ppm, Oxigênio <243>80 ppm, Cálcio <243>30 ppm, 15 a 50 ppm de Boro, Carbono 0,10 a 0,25%, Enxofre <0,050%, Alumínio <243>250 ppm.
