Back in the 1930s carbon graphite, China's Heilongjiang Jixi Liu Mao, Shandong Nanshu graphite graphite mine began production and processing. Beneficiation process was simple, poor labor conditions, low productivity, Qingdao graphite prices, only a few thousand tons of annual production. After decades of development, China's production of carbon and graphite products rising rapidly, 2004-2011, graphite and carbon products production CAGR of 22.12% molecular structure. 2011 graphite milk production of carbon and graphite products for 25,561,700 tons, an increase of 21.98%. Root causes of graphite carbon equivalent is floating too high. Thick slow solidification time provide conditions for floating graphite, graphite floating exacerbated. RE eutectic point to the left, above the residual amount of rare earth O. 06% graphite floating increased significantly. Magnesium eutectic point right, raise 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. Roughness graphite, carbon industry in the North Sea Dragon (certified), graphite is provided by Carbon Co., Ltd. Weifang North Sea Dragon. Carbon Co., Ltd.
