Abstract

APARELHO PARA AQUECIMENTO OU FUSãO POR INDUçãO EM GRADIENTE DE UMA PEçA DE TRAVALHO, E, MéTODO PARA AQUECER OU FUNDIR EM GRADIENTE UMA PEçA DE TRABALHO POR MEIO DE INDUçãO Um aparelho e processo são fornecidos para aquecimento ou fusão por indução em gradiente de uma peça de trabalho com uma pluralidade de bobinas de indução, é conectada a um suprimento de energia que pode ter um capacitor de sincronização conectado através da entrada de um inversor. A pluralidade de bobinas de indução é clocada de maneira seqüencial ao redor da peça de trabalho. O inversor tem uma saída de energia CA modulada em largura de pulso, que pode estar em controle síncrono com as saídas de energia CA moduladas em largura de pulso dos outros suprimentos de energia através de uma linha de controle entre os controladores de todos os suprimentos de energia.
