Well resistance to strong acid, strong alkali;
Good heat transfer performance of graphite crucible: for greatly shorten the melting time and save energy;
Ash content less than 0.1% , to ensure the precious metals in smelting is not contaminated;
In high-temperature using process, it got small thermal expansion coefficient;
And certain strain resistance to the thermal shock, quenching;
Long service life.
Utilization
Graphite crucible is generally used in alloy tool steel smelting and smelting of nonferrous metals and their alloys.
Graphite crucible can be used in the processing of graphite, graphite crucible,
graphite casting crucible tank,pull rods, mold and other graphite products.
Graphite crucible let the products are more durable than ordinary material products
longer service life, able to withstand more than 2000 degreeshigh temperature
Using Tips
Stored in dry place, do not get it wet
after drying the crucible , don't make it touch with water.
Be careful not to give a mechanical impact force, not from a fall or impact.
Package Included
