The main raw material of graphite crucible is crystalline natural graphite. So it maintains the natural physical and chemical properties of the original graphite.

That is: with good thermal conductivity and high temperature resistance, in the high temperature process, the thermal expansion coefficient is small, for acute heat, quenching has a certain anti-strain performance. The acid and alkaline solution corrosion resistance is strong, with excellent chemical stability.

Crucible model specifications are more in the application from the scale of production, batch size and smelting material varieties of restrictions, can be arbitrarily selected, applicability is strong, and can guarantee the purity of smelted material.

Graphite crucible, because of the above excellent performance, so in metallurgy, casting, machinery, chemical and other industrial sectors, was. Widely used in alloy tool steel smelting and melting of non-ferrous metals and their alloys and has a good technical and economic results.
