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.
