One of the main uses of graphite is to produce refractory materials, including refractory bricks, crucibles, continuous casting powder, mold cores, molds, detergents and high temperature materials. In recent years, two important changes in the refractory industry are the widespread use of magnesia-carbon bricks in the lining of steelmaking furnaces and the application of aluminum-carbon bricks in continuous casting. The graphite refractory is closely connected with the steel industry, the refractory material consumed by the steel industry worldwide
