Graphite crucible

The graphite crucible is mainly made of natural flake graphite as the main raw material, processed with plastic refractory clay or carbon as the binder, and has the characteristics of high temperature resistance, strong thermal conductivity, good corrosion resistance, and long service life. During high-temperature use, the coefficient of thermal expansion is small, which provides certain strain resistance for rapid cooling and heating. It has strong corrosion resistance to acidic and alkaline solutions, excellent chemical stability, and does not participate in any chemical reactions during the melting process. The inner wall of the graphite crucible is smooth, and the molten metal liquid is not easy to leak or adhere to the inner wall of the crucible, which makes the metal liquid have good fluidity and castability, suitable for casting and forming various molds. Due to its excellent characteristics, graphite crucibles are widely used in the smelting of alloy tool steel and non-ferrous metals and their alloys.
