Silicon Carbide Graphite Crucible

Graphite crucible is made of natural flake graphite as the main raw material and plastic refractory clay or carbon as the binder. It has the characteristics of high temperature resistance, strong thermal conductivity, good corrosion resistance and long service life. During high-temperature use, the thermal expansion coefficient is small, and it has certain strain resistance against rapid cooling and rapid heating. It has strong corrosion resistance to acidic and alkaline solutions, has excellent chemical stability, and does not participate in any chemical reactions during the smelting process. 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, making the metal liquid have good fluidity and casting properties, and is suitable for casting in various molds. Because graphite crucible has the above excellent characteristics, it is widely used in the smelting of alloy tool steel and the smelting of non-ferrous metals and their alloys.

1、The high density of graphite crucible gives the crucible better thermal conductivity

2、The graphite crucible has a special glaze layer and dense molding material on the outside, which greatly improves the corrosion resistance of the product and extends its service life;

3、The graphite components in the graphite crucible are all natural graphite, which has very good thermal conductivity. Do not place the graphite crucible on a cold metal table immediately after heating to avoid cracking due to rapid cooling.
