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.
Characteristic
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.
