2kg Graphite Quartz Crucible for Melting Metal Jewelry

Product Description

The graphite crucible is made of natural flake graphite as the main raw material and processed with plastic refractory clay or carbon as the binder. It has the characteristics of high temperature resistance, strong thermal conductivity, good corrosion resistance, long service life and so on. In the process of high temperature use, the coefficient of thermal expansion is small, and it has a certain strain resistance to rapid cooling and rapid heating. It has strong resistance to acidic and alkaline solutions, has excellent chemical stability, and does not participate in any chemical reaction 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, so that the metal liquid has good fluidity and castability, and is suitable for casting of various molds. Because graphite crucibles have the above excellent characteristics, they are widely used in the smelting of alloy tool steels and the smelting of non-ferrous metals and their alloys.
