Abstract

método de produção de chapa de aço elétrico com grão orientado. uma laminação a quente é executada em um aço com uma composição predeterminada contendo ti: 0,0020% em massa a 0,010% em massa e/ou cu: 0,010% em massa a 0,50% em massa para obter uma chapa de aço laminada a quente. um recozimentoé executado na chapa de aço laminada a quente para obter uma chapa de aço recozida. uma laminação a frio é executada na chapa de aço recozida para obter uma chapa de aço laminada a frio. um recozimento de descarburação e um recozimento de nitretação são executados na chapa de aço laminada a frio para obter uma chapa de aço descarburada nitrificada. então, um recozimento de acabamento é executado na chapa de aço descarburada nitrificada. quando se obtém a chapa de aço descarburada nitrificada, o aquecimento da chapa de aço laminada a frio é iniciado em uma atmosfera de carburação e nitretação, então o primeiro recozimento é executado a uma primeira temperatura dentro de uma faixa predeterminada, e então o segundo recozimento é executado a uma segunda temperatura dentro de uma faixa predetermiada.
