Abstract
Patente de Invenção: <B>"PROCESSO PARA PREPARAçãO DE TIRAS OU CHAPAS LAMINADAS A FRIO"<D>. A presente invenção refere-se a um processo para a produção de fitas ou chapas laminadas a frio a partir de aços de baixa liga com um máximo de 0,2% de C, AI, Ti, V, Nb respectivamente e um máximo de 1% de Si e Mn respectivamente, além de uma porção de boro requisitada para fixação de N (> 0,78 x N), o remanescente sendo constituído por ferro e impurezas inevitáveis, onde o referido aço é moldado após fundir em placas, placas finas ou uma fita, que são laminadas a quente a uma temperatura de partida acima de 1100°C e a uma temperatura final abaixo de Ar~ 3~, e onde a fita quente é então estirada e laminada a frio a uma temperatura abaixo de 650°C, depois do que a fita fria é recozida independentemente do grau de laminação a frio a uma temperatura baixa que poderia possivelmente variar, dependendo da composição do aço, de 520 até 780°C durante um período de tempo que é suficientemente longo para permitir uma completa recristalização. O processo descrito torna possível simplificar a fabricação e diminuir custos de produção associados com a fabricação de uma fita ou chapa laminada a frio completamente recristalizada.
