Pro Cast Foundry Clay High Purity Graphite Crucible Customized High Temp Resistance

Graphite crucible with natural flake graphite as the main raw material, to plastic refractory clay or carbon as binder processing, with high temperature resistance, strong thermal conductivity, good corrosion resistance, long service life and other characteristics. In the process of high temperature, the coefficient of thermal expansion is small, and it has certain strain resistance to rapid cooling and rapid heating. It has strong corrosion resistance to acidic and alkaline solutions and excellent chemical stability. It does not participate in any chemical reaction in the smelting process. The inner wall of 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 casting property, and is suitable for various kinds of mold casting. As graphite crucible has the above excellent characteristics, it is widely used in the smelting of alloy tool steel and non-ferrous metals and their alloys.
