Graphite Crucible

Short Description:

Graphite crucible has the characteristics of high temperature resistance, strong thermal conductivity, good corrosion resistance and long service life. In the process of high temperature use, the coefficient of thermal expansion is small, and it has certain strain resistance to quenching and rapid heat. It has strong corrosion resistance to acidic and alkaline solutions, excellent chemical stability, and does not participate in any chemical reaction during the smelting process. The graphite c...

Graphite crucible has the characteristics of high temperature resistance, strong thermal conductivity, good corrosion resistance and long service life. In the process of high temperature use, the coefficient of thermal expansion is small, and it has certain strain resistance to quenching and rapid heat. It has strong corrosion resistance to acidic and alkaline solutions, excellent chemical stability, and does not participate in any chemical reaction during the smelting process. The graphite crucible has an impurity (ash content) of less than 1% and is used for refining high-purity metals, as well as high-purity graphite (ash content <20 ppm) which has been specially purified. 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, and is suitable for casting of various molds. Due to the above excellent properties, graphite crucible is widely used in the smelting of alloy tool steel and the smelting of non-ferrous metals and their alloys.
