Graphite crucible has good thermal conductivity and high-temperature resistance; under high temperature, the thermal expansion coefficient is small, and rapid heating, quench with certain anti-strain properties. The strong corrosion resistance of acid, alkaline solution has excellent chemical stability. Graphite crucible, with their excellent performance, in metallurgy, casting, mechanical, chemical, and other industrial sectors, is widely used in smelting and alloy tool steel smelting of non-ferrous metals and their alloys. Besides,it has achieved good technical and economic results.
