Ultra-high temperature vacuum induction heating furnace

1. Mainly used for high-grade sintered of metal-ceramic materials, composite ceramic materials, functionally gradient materials and other materials.

2. Used For carbon materials, products and other materials (style repression, granular or powdered material) high-temperature heat treatment.

3. Working Principle: When the AC power input to the inductor, it will be formed alternating electromagnetic field in the inductor. When the magnetic of alternating electromagnetic field go through the special ZrB2 ceramic compound materials, the closed induced current will be generated due to the electromagnetic induction, which Kinds of currents called eddy current. Eddy current strength is proportional to the size of the EMF; and is inversely proportional to the reactance of eddy current circuit. Because the reactance of graphite crucible is very small, eddy current can reach very high values, and thus it will be generated the great heat at the graphite crucible inner, the temperature of crucible is rising, and the temperature of sample in the crucible will be also heated and rising.

4. Max. Temperature of ZrB2 ceramic compound materials is 2000℃.

5. Max. Temperature of high-strength composite graphite heat generator is 3000℃.

6. Select different of heat shield can be used in an oxidizing atmosphere and a vacuum atmosphere.

7. Alternatively various types of vacuum sintering furnace(2000℃, 2500℃, 2800℃, 3000℃).
