Graphite mold for continuous casting
Continuous casting graphite mold refers to graphite products used in continuous casting molds. Metal continuous casting technology is a new technology that directly turns molten metal into a material through a continuous casting mold. Because it does not undergo rolling and becomes a material directly, the secondary heating of the metal is avoided, so a lot of energy can be saved.
Continuous casting graphite is made from carbonaceous raw materials (pe...

Technical Characteristic
Main performance of graphite heater
The oxidation speed and volatilization speed of graphite affect the service life of the heating element. When the vacuum degree is 10-3~10-4 mmHg, the operating temperature should be below 2300℃. In the protective atmosphere (H2, N2, Ar, etc.), the operating temperature can reach 3000℃. Graphite cannot be used in the air, otherwise it will be oxidized and consumed.
The thermal expansion coefficient of graphite is small, and the size...
