Product Description

Product Description

High-precision graphite cooling box is an important part of the whole process of graphite smelting, especially precious metal smelting. The graphite crucible melts the metal into liquid state at high temperature in an induction furnace or resistance furnace, and then pours it into a pre-designed graphite cooling box to reshape the shape of the metal.

For example, at a high temperature of 1600ºC, after gold is melted into liquid state, it is poured into a high-purity graphite box with a volume of 100g, 200g, 250g, 500g, and 1000g measured in advance to make the corresponding gold nuggets.

In modern glass hot-melt forming process, high-purity graphite also plays an important role.
