melting copper furnace of a graphite crucible how to choose?

Copper melting graphite crucible / silicon carbide crucible smelting various gold, silver, copper, aluminum, lead, zinc and other non-ferrous metals, medium carbon steel, various rare metals and carbon products manufacturing. It is suitable for metal smelting in underground furnaces, electric furnaces, intermediate frequency furnaces and high frequency furnaces.

1. Good high temperature resistance of molten copper graphite crucible, the melting temperature can be as high as about 1800 ° C ;

2. Good thermal conductivity of graphite crucible for molten copper has a small thermal expansion coefficient, can conduct heat quickly, and has strong strain resistance to rapid heating and quenching;

3. The excellent chemical stability of the special crucible for melting copper has strong corrosion resistance to acid and alkaline solutions.
