Product Description :

Graphite Crucible

Graphite crucibles are widely used in the smelting of precious metals and the smelting of non-ferrous metals and their alloys in
metallurgy, foundry, machinery, chemical and other industrial areas because of their superior properties. And has a good technical
and economic effects.

Graphite crucible has more sizes, and not restricted to the production scale, quantity and smelting materials, it can be produced to any size, any quantity, and can ensure the purity of the smelting materials.

Graphite materials has the following characteristics：

1. High temperature resistance.
2. Good thermal conductivity.
3. Good corrosion resistance, long service life.
4. Small coefficient of thermal expansion, and it has a certain strain resistance to quench and heat.
5. Stable chemical property and hard to react.
6. Smooth inner wall, molten metal is not easy to leak and adhere to the inner wall of the crucible.

Specification：

We can process and customize according to customers' requirements
