Application of Induction Furnace Graphite Crucible :
Graphite crucibles are widely used in the smelting of precious
metals and the smelting of non-ferrous metals and their alloys in
metallurgy, foundry, machinery, chemical and other industrial areas
because of their superior properties.
Main features of Induction Furnace Graphite Crucible
1) High hardness.
2) High heat resistance: alumina ceramic has excellentthermal
stability,which means that it is widely used in areas where
resistance to high temperatures is essential.
3) Good wear resistance: alumina ceramic is the material of choice
for alumina wear parts.
4) High electrical resistivity: alumina is an electrically
insulating material.
