Equipment for heating in a vacuum environment. The pipe is connected with a high vacuum pump system in a metal housing or quartz glass cover chamber. Furnace Vacuum degree up to 133x (10-2~10-4) Pa. Furnace heating system can be directly with resistance furnace wire (such as tungsten filament) power-on heating, also can be used high-frequency induction heating. The maximum temperature can reach about 3,000 ℃.

Mainly used for ceramic sintering, vacuum smelting, electrical vacuum parts degassing, annealing, metal parts brazing, as well as ceramic-metal sealing and so on.
