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 graphite products. Graphite crucible let the products are more durable than ordinary material products， longer service life, able to withstand more than 2000 ℃ high 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.
