High pure graphite smelting crucible for melting gold

High pure graphite crucible for melting goldProduct Description
Graphite crucible is a utensil or melting tank vessels which use graphite powder and clay as main raw material, made through pressing in different molds (according to different needs) and firing process.

smelting crucibleAdvantages:
High strength (Flexural strength: 30Mpa Compressive strength: 55Mpa with rising of temperature, graphite strength increases)
High temperature resistance (graphite material melting point is 3850±50C)
Good heat shock resistance
Anti-oxidation,
Strong corrosion resistance to acid and alkali liquid
Abrasion resistance,
Good conductivity and thermal efficiency.
Excellent chemical stability
Small thermal expansion coefficient.
Easy to clean
smelting crucible Application:
Graphite crucible, with its special advantages and Plasticity, is widely used in the smelting area, e.g. gold smelting, silver smelting, aluminum smelting, and cooper smelting in metallurgy, casting, machinery, chemical and other industries.

smelting crucible Operating Notice:
The crucible should be stocked in the dry situation.
Carry the crucible carefully
Warm the crucible in the drying machine or near the furnace. The warming temperature should be up to 500℃.
The crucible should be put under the furnace mouth flat.

The crucible should be put in the center of the furnace and leave some distance between the crucible and furnace.
Turn the crucible once a week and this will help prolong the service life.
The flame should not touch the crucible directly.
