Graphite crucible for gold melting

Graphite crucible for metal melting and casting

Graphite crucible has good thermal conductivity and high temperature resistance. In high temperature use, the coefficient of thermal expansion is small, and it has certain strain resistance to rapid heating and cooling. It has strong corrosion resistance to acid and alkaline solutions and excellent chemical stability.

Graphite crucible has the above excellent properties, so it is widely used in the smelting of alloy tool steel and the smelting of non-ferrous metals and their alloys in metallurgy, casting, machinery, chemical industry and other industrial departments.

Canyon's gold melting graphite crucible has the following characteristics:

1. High density 1.88-1.9g/cm ³， High thermal conductivity, the thermal conductivity can reach 120-140w / m · K at 100 ℃;

2. The graphite crucible has a special glaze layer and dense molding materials, which greatly improves the corrosion resistance of the crucible and prolongs its service life;

3. The graphite components in the graphite crucible are all natural graphite, with very good thermal conductivity.

Other melting methods, such as reverberatory furnace and non crucible induction furnace, are suitable for mass melting of a single alloy. If the type of melting alloy is changed, metal pollution will occur if the refractory lining is not replaced. The graphite crucible cannot be placed on the cold metal table immediately after heating, so as to avoid its rupture due to rapid cooling.

Capacity of gold melting crucible

Common capacities are as follows: 1kg, 2kg, 2.5kg, 3kg, 4kg, 5kg, 5.5kg, 6kg, 8kg, 12kg, 16KG
