Graphite crucibles are widely used for smelting alloy tool steels and non-ferrous metals and their alloys in metallurgy, casting, machinery, chemical industry and other industrial sectors because of their excellent properties. And has a good technical and economic effect.

The types of crucibles can be roughly divided into three categories: the first type is copper smelting crucible, whose specification is "No.",; The second type is copper alloy crucible, with 150 special round crucibles and 150 round crucibles. The third type is steel-making crucible, with 150 crucibles.

The specification (size) of the crucible is usually indicated by the serial number. Crucible 1 has a capacity of melting 1500g of brass, and its weight is 180g. When melting different metals or alloys in the crucible, the melting amount can be calculated by multiplying the volume weight specification number of the crucible by the corresponding metal and alloy coefficient.
The raw materials for crucible production can be summarized into three types. The first is crystalline natural graphite, the second is plastic refractory clay, and the third is calcined hard kaolin skeleton clinker.

In recent years, high-temperature resistant synthetic materials, such as silicon carbide, alumina, corundum and ferrosilicon, have been used as the framework clinker of crucibles. This kind of clinker has a remarkable effect on improving the quality of crucible products and enhancing the density and mechanical strength of crucibles.
