[0002] Graphite crucible 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 and molding in various molds. Due to the above excellent characteristics, the graphite crucible is widely used in the smelting of alloy tool steel and the smelting of non-ferrous metals and their alloys. During the processing, the graphite crucible is usually supported by a flip structure to assist the metal liquid in casting the mold.
