High Purity Graphite Crucible
Graphite crucibles have excellent performance. In the process of high temperature use, the thermal expansion coefficient is small, and it has certain strain resistance to rapid cooling and rapid heating. Therefore, it is widely used in the smelting of alloy tool steel and the smelting of non-ferrous metals and their alloys. Generally, graphite crucibles can be used to smelt non-ferrous metals such as copper, brass, gold, silver, zinc and lead and their alloys. The inner wall of the graphite crucible is smooth, and the molten metal liquid is not easy to leak and adhere to the inner wall of the crucible, so that the metal liquid has good fluidity and castability.
