Abstract
"PROCESSO APERFEIçOADO PARA PRODUçãO DE TIRA DE AçO ELéTRICO NãO-ORIENTADO". A presente invenção refere-se a um processo para produção de um aço elétrico não-orientado com aperfeiçoadas propriedades magnéticas e aperfeiçoada resistência à formação de sulco, fragilidade, entupimento de bocal e envelhecimento magnético. O aço transportando cromo é produzido a partir de uma fusão de aço que é moldada como uma chapa fina ou chapa convencional, resfriada, laminada quente e/ou laminada fria em uma tira acabada. A tira acabada é ainda submetida a pelo menos um tratamento de têmpera onde as propriedades magnéticas são desenvolvidas, tornando a folha de aço da presente invenção apropriada para uso em maquinaria elétrica como motores ou transformadores.
