Abstract

Patente de Invenção: "PROCEDIMENTO PARA A FABRICAçãO DE CHAPAS ELETROMAGNéTICAS DE GRãOS NãO ORIENTADOS". A invenção refere-se a um procedimento para a fabricação de chapas eletromagnéticas de grão não orientado, onde o material de partida de aço contém lingotes preiaminados e aquecidos sobretudo a uma temperatura de reaquecimento <243> 1250<198>C assim como fitas fundidas aplicadas diretamente ou lingotes finos aplicados diretamente e que contém (em % em massa) C: <243> 0,06%, Si: 0,03 - 2,5%, AI: < 0,4%, Mn: 0,05 - 1,0%, S: <243> 0,02%, eventualmente outros aditivos de ligas e como resto o ferro assim como elementos de acompanhamento usuais, com uma temperatura de entrada de <243> 1100<198>C em um laminador final de escalonamento onde é laminado a quente para a constituição de uma fita quente com espessura < 3,5 mm para uma temperatura final de laminação (T~ ET~) <242> 770<198>C, onde a fita quente é bobinada em uma temperatura de bobinagem (T~ HT~) dependente da temperatura final de laminação, sendo em seguida decapada e, após a decapagem é laminada em várias passagens de laminação para a formação de uma fita fria com uma espessura de 0,2 - 1 mm para um grau de conformação global máximo de 85% e onde a fita fria é submetida a um tratamento final. Este procedimento possibilita fabricar um conjunto de chapas largas com chapas eletromagnéticas de grãos não orientados e de alta qualidade, com características magnéticas melhoradas.
