Abstract

resumo patente de invenção: "chapa de aço elétrica de grão orientado e método para produção da mesma". a presente invenção refere-se a uma chapa de aço elétrica de grão orientado com perda de ferro reduzida ao longo de uma ampla faixa de espessura de chapa, fornecendo-se uma chapa de aço elétrica de grão orientado com uma espessura de chapa t (mm) realmente medida que inclui uma região de domínio de fechamento que se estende linearmente em uma direção de 60° a 120° em relação à direção de laminação sobre uma superfície da chapa de aço, sendo que a região de domínio de fechamento é formada periodicamente em um espaçamento s (mm) na direção de laminação, tal que h = 74,9t + 39,1 (0,26 = t); h = 897t - 174,7 (t > 0,26), (w × h)/(s × 1.000) = -12,6t + 7,9 (t > 0,22), e (w × h)/(s × 1.000) = -40,6t + 14,1 (t = 0,22), onde h (µm) é a largura e w (µm) é o comprimento da região de domínio de fechamento.
