Abstract
"PROCESSO PARA PRODUçãO DE TIRAS DE AçO ELéTRICO DE GRãO ORIENTADO". A presente invenção se refere a um processo para produção de tiras de Fe-Si elétricas de grão orientado, em que uma liga contendo Si é diretamente fundida na forma de tiras contínuas de 2,5 a 5 mm de espessura, laminadas a frio em uma ou mais etapas com recozimento intermediário para uma espessura final compreendida entre 1 e 0,15 mm, a tira sendo depois continuamente recozida para realizar a recristalização primária e subseq³entemente recozida para realização da recristalização secundária orientada, caracterizado em que após a solidificação da tira e antes de seu embobinamento, é induzida na matriz de metal uma transformação de fase de ferrita para austenita, para uma fração de volume entre 25 e 60%, obtida mediante controle da composição da liga, de modo que tal fração de austenita é admitida dentro do equilibrio de estabilidade entre as duas fases e deformando a tira por meio de laminação em linha com a etapa de fundição, obtendo uma deformação acima de 20%, na faixa de temperatura entre 1000 e 1300<198>C.
