Fire resistant industry

Because of its boiling point of 4250℃ and a melting point of about 3850℃, graphite is one of the non-metallic materials with high temperature resistance and widely used. Because of its low thermal expansion coefficient, graphite loses less weight even when it is burned at high temperature. Therefore, graphite is used as a material in both fire-resistant or high-temperature-resistant materials. 

Because graphite has many excellent properties, it is widely used in metallurgy, machinery, electrical, chemical, textile, national defense and other industrial sectors. A major use of graphite is the production of refractory materials, including refractory bricks, crucible, continuous casting powder, die core, mold, and high temperature resistant materials. 

Graphite products can also be made of carbon refractory materials in the electric resistance furnace by 2,500 ~ 2,800℃ of thermal insulation, and make it graphitized. In recent years, two important changes in the refractory industry are the wide application of magnesium carbon brick in the steelmaking furnace lining, and the application of aluminum carbon brick in continuous casting.
