Graphite crucible has good thermal conductivity and high temperature resistance, in the high temperature process, the thermal expansion coefficient is small, for acute, quenching with a certain anti-strain performance. The acid and alkaline solution corrosion resistance is strong, with excellent chemical stability.
Graphite crucible, because of the above excellent performance, so in metallurgy, casting, machinery, chemical and other industrial sectors, is widely used in alloy tool steel smelting and melting of nonferrous metals and alloys. And has a good technical and economic results.
Domestic graphite crucible production technology has reached or even more than the import of crucible, high-quality domestic crucible has the following characteristics:
1, graphite crucible high density makes the crucible with the best thermal conductivity, the thermal effect is significantly better than other imported crucible;
2, graphite crucible appearance of a special glaze layer and dense molding materials, greatly improving the product's corrosion resistance, to extend its service life;
3, graphite crucible in the graphite components used in all natural graphite, thermal conductivity is very good. After the graphite crucible is heated, it can not be immediately placed on a cold metal table to avoid cracking due to abrupt cooling. Many types of alloy melting are most suitable for use with crucibles. To change the type of alloy, only need to exchange graphite crucible can be. Other melting methods such as reverberatory furnace and non-crucible induction furnace melting, suitable for a single alloy of a large number of melting, if the conversion of alloy melting type, if you do not replace the lining of the refractory material, metal pollution occurs.
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 smelting substances.
Graphite crucible, because of the above excellent performance, so in metallurgy, casting, machinery, chemical and other industrial sectors, is widely used in alloy tool steel smelting and melting of nonferrous metals and alloys. And has a good technical and economic results.
