Abstract

"SISTEMA DE FORNO DE INDUçãO E MéTODO DE FUNDIR E AQUECER INDUTIVAMENTE UM MATERIAL ELETRICAMENTE CONDUTOR EM UM CADINHO". Um sistema de forno de indução tem uma bobina de indução ativa envolvendo um cadinho. Uma bobina de indução passiva também envolve o cadinho. A bobina de indução passiva fica conectada em paralelo com um capacitor para formar um circuito tanque L-C. Uma fonte de corrente ac é provida para ativar a bobina de indução para produzir um campo magnético que aquece e funde indutivamente um material eletricamente condutor no cadinho. O campo magnético também acopla magneticamente com a bobina de indução passiva para induzir uma corrente na bobina de indução passiva. Esta corrente induzida gera um campo magnético que aquece e funde indutivamente o material. A resistência do circuito tanque LC é refletida no circuito da bobina de indução ativa para melhorar a eficiência global do sistema de forno de indução. O cadinho pode ter a extremidade aberta para permitir a passagem de material eletricamente condutor pelo cadinho durante o processo de aquecimento.
