Graphite crucible has good thermal conductivity and high temperature resistance. During high temperature use, the thermal expansion coefficient is small, which has a certain resistance to hot and quenching. It has strong corrosion resistance to acid and alkaline solution, and has excellent chemical stability. Because of its excellent properties, graphite crucible is widely used in metallurgy, foundry, machinery, chemical industry and other industrial sectors, and is widely used for smelting alloy tool steel and smelting non-ferrous metals and alloys, and has good technical and economic effects. The main material of the graphite crucible is the crystalline natural graphite, which maintains the original physical and chemical properties of the natural graphite. Graphite has strong corrosion resistance to acid and alkaline solution, and has excellent chemical stability.
The production technology of the domestic graphite crucible has reached or even exceeded the imported crucible. The quality of the domestic graphite crucible has the following characteristics:
1, the high density of graphite crucible makes the crucible with the best thermal conductivity, and its heat conduction effect is obviously better than that of other imported crucible.
2, the graphite crucible has a special glaze layer and compact forming material, which greatly improves the corrosion resistance of the product and prolongs its service life.
3. The graphite crucible in the graphite crucible is all natural graphite, and the thermal conductivity is very good. When the graphite crucible is heated, it should not be immediately placed on a cold metal table to prevent it from cracking due to sharp cooling.
