Exist in the form of carbon is varied, there is crystalline elemental carbon such as diamond, graphite; amorphous carbon such as coal; complex organic compounds such as animals and plants and the like; carbonates such as marble and the like. Physical and chemical properties of elemental carbon depends on its crystal structure. Diamond and graphite soft creamy Qingdao graphite crystal structure different high hardness, each have their own appearance, density, melting point. Graphite products after the release of far infrared heating. MgO-C refractories is the mid-magnesium carbon graphite, successfully developed by the United States, dating, Japanese steel industry began to MgO-C for cooling water in an electric arc furnace smelting. Currently in the world have been widely used in steelmaking graphite carbon brick milk, and has become a traditional uses graphite. Early age, began to be used carbon brick lining BOF. Aluminum aluminum carbon carbon brick is mainly used for continuous casting refractories, flat slab self-bit pipeline Fort Hood, Bangalore and other underwater nozzle and oil wells. In Japan, more than the total production volume of steel produced by continuous casting. Pingdu graphite, graphite, carbon industry is provided by the North Sea Dragon Sea Dragon Carbon Co., Ltd.
