The casting industry in the mechanical industry uses graphite materials as molds such as pressure casting, centrifugal casting, and hot squeeze of super hard alloy. It can use graphite molds as large as train wheels and small as small as precision parts. Graphite molds can be repeatedly used for multiple times. After the molding, the casting has a high degree of smoothness, and some can be used without further processing. The graphite material used for casting molds should be graphite with a dense texture, low thermal expansion coefficient, and good antioxidant performance. Graphite, which is used for casting with large casting size, can be composed of thicker particle size. It is used for casting small precision parts The graphite must be graphite with fine particles. The number of graphite used to make molds in China is large. In 2005, it was continuously cast about 1500T with graphite and sintering molds were estimated to cost 4000T. Table 4 is the specifications and technical performance of fine particles produced by Jiman Group Shanghai Carbon Factory.

In the mold graphite, the quality requirements of continuously casting graphite with metal graphite are the strictest. It is required to have high thermal conductivity, good thermal stability and heat resistance, good lubrication, not infiltrate with melting metal Become accurate mold. The characteristics of continuous casting graphite are generally as follows: volume density of 1.7-1.9g/cm, anti-folding strength 30-40MPa, tensile strength 20-30MPa, and thermal guidance rate of 100 <130 w/(m · k).

The vertical corner plate is 1260 mm x 200 mm x 280 mm; the horizontal plate is 1000 mm x 70 mm x 240 mm; the casting speed varies according to the size of the casting plate, and the range range is 0.7 ~ 4 m/min. Cold mold pressing fine particles structure graphite or fine particle structure graphite with static pressure can be processed into metal continuous casting graphite pieces
