Melting furnace crucible

Melting furnace crucible is a specialized inner pot crucible used for melting furnaces, lead melting furnaces, aluminum melting furnaces, and zinc melting furnaces. Melting furnace crucibles are usually divided into cast iron crucibles, stainless steel crucibles, clay crucibles, graphite crucibles, and corundum crucibles according to the crucible material.

The most commonly used crucible for melting furnaces is cast iron crucible, which is made by recasting pig iron and used as a utensil for melting metals such as aluminum alloy, zinc alloy, lead alloy, tin alloy, antimony alloy, etc.

The graphite crucible system is a high-grade refractory vessel made of natural flake graphite, wax stone, silicon carbide and other raw materials, used for smelting, casting copper, aluminum, zinc, lead, gold, silver and various rare metals.

The specifications (size) of a crucible are usually represented by sequential numbers. The first crucible has a capacity to melt 1000g of brass and weighs 180g. When melting different metals or alloys, the melting amount of the crucible can be calculated by multiplying the bulk density specification number of the crucible by the corresponding metal and alloy series.
