摘要： A plasma melting furnace has a melting chamber having an anode torch and a cathode torch made of graphite and having a electric conductor disposed on the bottom thereof. When the furnace is operated, the anode torch, having an inflow of electrons, which forms an unstable plasma are is contacted with the electric conductor and is not used, while the cathode torch, having an outflow of electrons, which forms a stable plasma are is utilized for heating, whereby the furance can be stably and continuously operated. Thus, since the cathode torch which is used is not heated so much and the anode torch, which is liable to be heated to a great degree, is not used, the electrode consumption rate can be greatly reduced.
摘要翻译： 等离子体熔融炉具有熔融室，其具有由石墨形成的阳极喷灯和阴极喷管，并且在其底部设置有导电体。 当操作炉子时，形成不稳定等离子体的具有电子流入的阳极炬与电导体接触，并且不使用，而具有形成稳定等离子体的电子流出的阴极炬是 用于加热，从而可以稳定和连续地运行。 因此，由于不使用所使用的阴极炬，所以不能使用容易被加热的阳极炬，因此能够大大降低电极消耗率。
