Abstract

fornalha de arco a vácuo de eletrodo consumível não resfriado por água para processo contínuo. uma fornalha de arco a vácuo de eletrodo consumível e, mais particularmente, uma fornalha de arco a vácuo de eletrodo consumível de corrente contínua é fornecido, em que nenhum resfriamento por água é necessário para resfriar tipicamente nenhum dos eletrodos, nem quaisquer outras partes da fornalha, e isso inclui a cuba, as portas de flanges e as conexões elétricas da fornalha. a presente fornalha usa eletrodos não metálicos, tais como eletrodo de grafite, que são adequados para fusão de metais, fundição de minérios metálicos, e óxido metálico para metal elementar onde o uso de eletrodos de grafite é uma prática comum. a presente fornalha e montagens de eletrodo tornam possível realizar um verdadeiro processo contínuo de fusão e fundição sob pressão controlada.
