Use and classification of graphite crucible
Graphite crucible is widely used in the smelting of alloy tool steel and the smelting of nonferrous metals and their alloys in metallurgy, foundry, machinery, chemical industry and other industries because of its excellent properties. And has the better technical economical effect. The graphite crucible is mainly divided into natural graphite crucible, artificial graphite crucible and high purity graphite crucible.
Natural graphite crucible is made of flake graphite after mixing, molding and other processing, mainly used for the use of temperature is not high, the technical requirements of the industry is not high, low cost, short service life.
The artificial graphite crucible is made by mixing petroleum coke and asphalt and roasting, graphitization and machining. It is mainly used in industries with high temperature, complicated service environment and high technical requirements, with medium cost and relatively long service life.
High purity graphite crucible is a high-end product, mainly used in precious metal smelting, etc., with high cost.
