Product Description

 

Product Description

                                                          Graphite Block
Graphite block is made of domestic petroleum coke, with carbon content above 99%.  We have vibrated,molded and isotropic graphite block.  They are widely used in such fields as mechanical , electronics, chemical industry and other new industries.  

Graphite block has excellent corrosion resistance, resistance to molten metal erosion and melt erosion, high thermal conductivity, good thermal shock resistance, also has sufficient oxidation resistance and good anti-leakage properties.


We can machine to specific shapes according to customers' requirements.

Nature:

1. Thermal stability: According to the quench acute thermal using conditions of graphite blocks, we will specially design the production procedure, so as to ensure the reliability of product quality.
2. Corrosion resistance: Even and fine basic design will delay the erosion of graphite plate.
3. Impact resistance: Graphite plate can bear high thermal impact, so any process can be carried out.
4. Acid resistance: The adding of special materials will greatly improve the quality of crucible, especially its index of acid resistance., and will prolong the service life of graphite plate
