Abstract

"FORNO DE INDUçãO PARA OPERAçãO EM ALTAS TEMPERATURAS". Um forno de indução capaz de operação em temperaturas superiores a 3.100<198>C tem uma montagem (60) de esfriamento, a qual é montada seletivamente em uma extremidade superior da parede (76) do forno. A montagem de esfriamento inclui um domo (62), o qual é esfriado ativamente pelas serpentinas (68) de água de esfriamento. Durante a parte de esfriamento de um curso de operação do forno, o esfriamento inicialmente ocorre naturalmente, mediante condução de calor para fora da zona quente através de uma camada (58) isolante do forno. Quando a temperatura dentro da zona quente (20) do forno atingir aproximadamente 1.500<198>C, um mecanismo (80) de levantamento, montado no domo, levanta ligeiramente a cobertura (16) do forno, permitindo que gases quentes a partir da zona quente se misturem com o gás mais frio no domo. Isso acelera o esfriamento da zona quente, reduzindo significativamente os tempos de esfriamento, sem a necessidade de atravancar o próprio forno com válvulas ou outros mecanismos complexos de esfriamento os quais têm que ser substituídos periodicamente. A vida útil de um susceptor (10) de grafite do forno na elevada temperatura de operação é aumentada mediante ação de envolver o susceptor com uma camada (40) de barreira de grafite flexível, que inibe a evaporação da grafite. Adicionalmente, discos (154) de verificação colocados dentro do susceptor, proporcionam um perfil exato da temperatura da zona quente.
