Features:
? Well thermal stability : according to the using conditions of graphite crucible snap heat and cold;
? Well corrosion resistance， impact resistance performance， to ensure the reliability of product quality;
? 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 ℃ 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.
