Abstract

chapa de aço elétrica orientada por grão. a presente invenção refere-se a uma chapa de aço elétrica orientada por grão tendo uma estrutura de domínio magnético modificada por introdução de tensão sem um vestígio de tratamento, em que o ruído gerado quando a chapa de aço elétrica orientada por grão é usada laminada em um núcleo de ferro de um transformador é efetivamente reduzido por: ajuste de uma densidade de fluxo magnético b~ 8~ a 1,92 t, ou mais alta; em seguida ajuste de uma proporção de largura de domínio magnético média da superfície tratada após tratamento de introdução de tensão w~ a~ para largura de domínio magnético média antes do tratamento de introdução de tensão w~ 0~ como w~ a~/w~ 0~ <0,4; e ajuste de uma proporção de w~ a~ para largura de domínio magnético média da superfíce não tratada w~ b~ como w~ a~/w~ b~ >0,7; e adicionalmente, ajuste de uma proporção de largura média da porção descontínuada de domínio magnético w~ d~ na superfície não tratada para largura média da porção descontínua de domínio magnético w~ d~ na superfície não tratada para largura média da porção descontínua de domínio magnético na superfície tratada resultante de tratamento de introdução de tensão w~ c~ como w~ d~/w~ c~ > 08; e ajuste de w~ c~ < 0,35 mm.
