Product Description

 Graphite Crucible Graphite mould  for silver Gold copper brass Melting casting 
Graphite crucible, graphite boat and graphite stirring rod :Used for gold, silver and other jewelry casting and recasting.

• 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;
• In high-temperature using process, it got small thermal expansion coefficient;

     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 2600C high temperature
