Because graphite has many excellent properties, and thus in the metallurgical, mechanical, electrical, chemical, textile, defense and other industries widely used. Can be used for refractories. Graphite flake graphite products to maintain the original chemical properties also has a strong self-lubricating properties. Characteristics of the graphite powder, i.e. the acid resistance of high strength, corrosion resistance and high temperature and low temperature 3000 ℃ -204 ℃, while its compressive strength is greater than 800kg / Cm2, and antioxidant carbon graphite, 1% weight loss in air at 450 ℃, Rebound rate of 15-50% (density of 1.1-1.5). So graphite products has been widely used in metallurgical, chemical, petrochemical, high-energy physics, aerospace, electronics and other areas. Root causes of graphite carbon equivalent is floating too high. Thick slow solidification time condition roughness provides quality graphite graphite floating, floating exacerbated graphite. RE eutectic point to the left, above the residual amount of rare earth O. 06% graphite floating increased significantly. Magnesium graphite eutectic point to the right, increase the amount of residual magnesium, reducing graphite float. Prolonged high temperature molten iron pouring remain liquid in the type of time, increasing the graphite float. Burden original graphite large size, quantity, unmelted graphite particles promote the nucleation of graphite and graphite under floating liquid precipitation. With the rapid development of China's metallurgical, chemical, machinery, medical equipment, nuclear power, automotive, aerospace and other industries, these industries demand for carbon and graphite products will continue to grow, our graphite and carbon products industry will maintain rapid growth . According to "China graphite and carbon products industry development prospects of strategic planning and investment analysis report Prospects" Statistics, 2006-2011, China's carbon and graphite products industry sales compound annual growth rate of 36.56%. According to the current domestic and international economic situation, combined 2006-2011 China graphite and carbon products industry sales data and Chinese economic growth data, a rough estimate for 2012-2015 of graphite and carbon products industry sales compound annual growth rate of 21% in 2015, China's carbon and graphite products industry sales will reach 340 billion yuan.
