high purity grahite crucible

 

1.MATERIAL & PRODUCTION PROCESS

 

The moulded graphite is made from the raw materials of high quality pitch, petroleum coke and other aggregate and binding materials, through the processing of grinding, kneading, second grinding, moulded forming, baking, impregnation with pressure, second baking, graphitization in high temperature, refinement etc. We use this kind of graphite material to make graphite crucible.

 

2.PRODUCTION ADVANTAGES:

 

High purity, high density, fine grain, experienced staff, good service, competitive price, good performance of electrical conductivity and thermal conductivity, good corrosion resistance, thermal shock resistance, thermal stability, high mechanical strength, low permeability, and good oxidation resistance,good lubrication,homogenuous structure,etc.

 

 

 

 

 

a.    Thermal stability: We make special design to assure the quality according to the instant temperature changing working condition.

 

 

 

 

 

 

 

b.    Corrosion resistance: Precise design extends the ability of corrosion resistance of the crucible.

 

 

 

 

 

 

 

c.     Impulsion resistance: graphite crucible can stand very strong heat impulsion, so it can be freely used in any technique process.

 

 

 

 

 

 

 

d.    Acid resistance: Impregnation of special stuff can improve the quality of the crucible and it is outstand in the acid resistance. As a result, it can prolong the work life of the graphite crucible.

 

 

 

 

3.APPLICATION:

 

For Non-ferrous Metal Continuous Casting and Precious Metal Smelting, for Cemented Carbid,etc.

Notes of Usage for the Graphite Crucibles:

 

1. Be carefully Of Storage and handling.

 

2. Choose the suitable base. Put on the right position.

 

3. Additives should not be too much. Be carefully.

 

4. Burner flame shall not be directly to crucibles.

 

5. The influence of deslagging agent.

 

6. Adhesion oxide will cause crucible rupture.
