Abstract

método para produção de chapa de aço elétrico com grão orientado. a presente invenção refere-se a um método para produção de uma chapa de aço elétrico com grão orientado, incluindo preparar como material uma placa de aço tendo uma composição predeterminada e executar pelo menos duas operações de laminação a frio, caracterizadas pelo fato de que um tratamento térmico é executado, antes de qualquer uma das operações de laminação a frio exceto a laminação a frio final, a uma temperatura na faixa de 500ºc a 750ºc por um período de tempo na faixa de 10 minutos a 480 horas. a chapa de aço elétrico com grão orientado da presente invenção apresenta, através da utilização da transformação austenita-ferrita, propriedades magnéticas superiores após a recristalização secundária.
