Abstract

"MéTODO PARA PRODUZIR AçO ELéTRICO DE GRãO ORIENTADO DE ALTA PERMEABILIDADE E MéTODO DE RECOZIMENTO INICIAL DE FITA DE AçO ELéTRICO DE GRãO ORIENTADO E ALTA PERMEABILIDADE". A presente invenção apresenta um método de produzir um aço elétrico de grão orientado de alta permeabilidade tendo excelentes propriedades mecânicas e magnéticas. Uma fita quente tendo uma espessura de cerca de 1,5 a cerca de 4,0 mm tem uma química compreendendo de cerca de 2,5 a cerca de 4,5% de silício, de cerca de 0,1 a cerca de 1,2% de cromo, de cerca de 0,02 a cerca de 0,08% de carbono, de cerca de 0,01 a cerca de 0,05% de alumínio, até cerca de 0,1% de enxofre, até cerca de 0,14% de selênio, cerca de 0,03 a cerca de 0,15% de manganês, até cerca de 0,02% de estanho, até cerca de 1% de cobre e o balanço sendo essencialmente ferro e elementos residuais, todas as porcentagens em peso. A fita tem uma resistividade volumétrica de pelo menos 45 <109><87>-cm, uma fração volumétrica de austenita (<sym>~ 1150<198>C~) de pelo menos 20% e a tira tem uma espessura de camada isomórfica de pelo menos cerca de 2% da espessura total em pelo menos uma superfície da fita processada a quente. A fita é rapidamente esfriada após recozimento antes da laminação a frio a uma taxa de pelo menos 30<198>C/s de 875 a 950<198>C até uma temperatura abaixo de 400<198>C. A fita é reduzida a frio em um ou mais estágios com uma redução final de pelo menos 80%, recozida, descarburada e revestida com um separador de recozimento em pelo menos um lado. Um recozimento final proporciona crescimento secundário de grão estável e uma permeabilidade medida em a A/m de pelo menos 1840.
