Detailed description：

Graphite crucible has good thermal conductivity and high temperature resistance. During high temperature use, the thermal expansion coefficient is small, which has a certain resistance to hot and quenching. It has strong corrosion resistance to acid and alkaline solution, and has excellent chemical stability. In the metallurgical, foundry, mechanical, chemical and other industrial sectors, it is widely used for smelting of alloy tool steel and smelting of nonferrous metals and their alloys. And it has a better technical and economic effect.
