The raw material of the graphite crucible is crystalline natural graphite. The graphite crucible has high density, good thermal conductivity and high temperature resistance. When it is used in the process of high temperature, the coefficient of thermal expansion is small, and it has certain strain resistance for sudden changes of temperature. It has strong corrosion resistance to acid and alkaline solution, long service life and excellent chemical stability.
Graphite crucible is widely used in the metallurgy, foundry, machinery, chemical and other industrial sectors for the smelting of alloy tool steel and the smelting of non-ferrous metals and their alloys. And it has a good technical and economic effect.
