Graphite crucible use and classification

Because of its excellent performance, graphite crucibles are widely used in the smelting of alloy tool steels and the smelting of non-ferrous metals and their alloys in metallurgy, casting, machinery, chemical and other industrial sectors. And has a good technical and economic effect. Graphite crucibles are mainly divided into: natural graphite crucible, artificial graphite crucible, high-purity graphite crucible, etc. .

Natural graphite crucible is made of flake graphite through kneading, forming, etc. It is mainly used in industries where the temperature is not high and the technical content is not high, with low cost and short service life.

Artificial graphite crucible is kneaded with petroleum coke and pitch, and is made through roasting, graphitization, machining, etc. It is mainly used in industries with high temperature, complex use environment and high technical requirements. The cost is medium and the service life is relatively long. long.

High-purity graphite crucible is a high-end product, mainly used for precious metal smelting, etc., and the cost is relatively high.
