Material: High fine particle graphite thermal stability : according to the using conditions of graphite crucible snap heat and cold; corrosion resistance, impact resistance performance, to the reliability of product quality; resistance to strong acid, strong ;
Good heat performance of graphite crucible: for greatly shorten the melting time and save energy;
Ash content less than 0.1% , to 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 .
Graphite crucible let the are more durable than ordinary material , service life, to withstand more than 2000 Celsius high temperature
Using Tips
Stored in dry place, do not it wet
after drying the crucible , 't touch with water.
