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 ℃ 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.
