Graphite crucible for melting silver, graphite crucible for melting gold, graphite crucible for melting copper uses graphite as the main raw material and plastic refractory clay or carbon as binder processing. This kind of graphite crucible is mainly used for gold, silver, copper, aluminum, brass and other non-ferrous metal and alloy smelting. Graphite crucible's wall is smooth and the melting loss of precious metals is small.

HOW TO USE GRAPHITE CRUCIBLE FOR MELTING GOLD/ SILVER/ ALUMINIUM/ COPPER/ BRASS

Graphite crucible is most afraid of damp, damp after the quality has a great impact, if the use of damp crucible will be broken, burst, off the bottom and other phenomena, resulting in the loss of molten metal, and even industrial accidents.

So graphite crucible in storage and use process, must pay attention to moisture-proof.

ADVANTAGES OF GRAPHITE CRUCIBLE FOR MELTING GOLD/ SILVER/ ALUMINIUM/ COPPER/ BRASS

01
Graphite crucible has the characteristics of high temperature resistance, strong thermal conductivity, good corrosion resistance, long service life and so on. In the process of high temperature, the coefficient of thermal expansion is small, and it has certain strain resistance to rapid cooling and rapid heating.

02
Graphite crucible for melting silver/gold/aluminium/copper/brass has strong corrosion resistance to acidic and alkaline solutions and excellent chemical stability. It does not participate in any chemical reaction in the smelting process.
