Abstract

APARELHO PARA AQUECIMENTO OU FUSçO POR INDUÇçO ELÉTRICA DE UM MATERIAL ELETRICAMENTE CONDUTIVO, E, MÉTODO DE CONTROLE DE AQUECIMENTO OU FUSçO POR INDUÇçO ELÉTRICA DE UM MATERIAL ELETRICAMENTE CONDUTIVO. Um aparelho e processo são fornecidos para controlar o aquecimento ou fusão de um material eletricamente condutivo. A potência édirecionada seletivamente entre seções da bobina circundando zonas diferentes do material por alteração da freqúência de saída da fonte de alimentação de potência para as seções da bobina. As seções de bobina compreendem pelo menos uma seção de bobina ativa, que é conectada a saída da fonte de alimentação de potência, e pelo menos uma seção de bobina passiva, que não é conectada à fonte de alimentação de potência, mas é conectada em paralelo com um capacitor de sintonização de maneira que a pelo menos uma seção de bobina passiva opera a uma freqúência ressonante e a freqúência de saída da fonte de alimentação de potência é alterada de maneira que a potência induzida na pelo menos uma seção de bobina passiva se altere à medida que a freqúência é alterada.
