Crucible with thick wall

Crucible with thick wall is made of high-purity graphite as the main raw material It 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 a certain anti strain performance for rapid cooling and rapid heating. It has strong corrosion resistance to acidic and alkaline solutions, excellent chemical stability, and does not participate in any chemical reaction in the smelting process. The inner and outer walls of the graphite crucible are polished to make the appearance smooth. 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. It is suitable for casting in various molds. Due to the above excellent characteristics of graphite crucible, high purity graphite crucible is widely used in smelting alloy tool steel and nonferrous metals and their alloys.
