The material of graphite crucible can be divided into
artificial graphite,clay bonded graphite,
and carbon bonded graphite.Artificial graphite crucible is made of
graphite electrode as material and made out.
Clay bonded graphite, the main ingredient is natural crystal
graphite and clay Now only used in
small amount of high-temperature melting of cast iron, cast steel
melting and melting of precious metals.
Carbon bonded graphite, the main ingredient is natural crystal
graphite and silicon carbide.
Mainly used in the melting of the majority of
non-ferrous metals such as copper alloy and aluminum alloy
a. High thermal conductivity
b.Thermal shock resistance
c.High temperature resistance
d. Mechanical shocks resistance
d. Oxidation resistance
f. Small metal contamination
g. Good clearner
standard type,long type,bowl type,lip type, electric
melting of copper alloy and light metal alloy
