Abstract

patente de invenção: método para produção de chapa de aço elétrico com grão orientado. o objetivo da presente invenção é propor um método para alcançar estavelmente um bom efeito de reduzir a perda de ferro pelo tratamento de aquecimento rápido de uma chapa de aço em um caso em que o recozimento de recristalização primária incluindo o tratamento de aquecimento rápido é executado em um método para produção de uma chapa de aço elétrico com grão orientado usando um material isento de inibidores. especificamente, a presente invenção fornece um método para produção de chapa de aço elétrico com grão orientado, compreendendo as etapas de: preparar um placa de aço na qual os teores de componentes inibidores foram reduzidos, isto é, teor de al de 100 ppm ou menos, e teores de n, s e se: 50 ppm respectivamente; submeter a placa de aço â laminação a quente e então ou a um processo de laminação a frio única ou a dois ou mais processos de laminação a frio interpondo-se recozimento(s) intermediário(s) entre eles para obter uma chapa de aço tendo a espessura final; e submeter a chapa de aço ao recozimento de recristalização primária e então ao recozimento de recristalização primária e então ao recozimento de recristalização secundária onde o recozimentop de recristalização primária inclui aquecer a chapa de aço até uma temperatura igual a ou maior que 700<198>c a uma taxa de aquecimento de pelo menos 150<198>c/s, resfriar a chapa de aço até uma faixa de temperatura de 700<198>c ou menos, e então aquecer a chapa de aço até a temperatura de enxágüe a uma taxa média de aquecimento não excedendo 40<198>c/s em uma zona de aquecimento subsequente.
