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 left Qingdao graphite sold, higher than 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. Ferrous metallurgy casting graphite mold: To shorten the production process, down at the end costs, improve quality, reduce labor intensity and pollution of the environment, more than 20 years of metal materials production gradually to the casting direction. Since copper, aluminum and even the basic realization of production of the mold of high-purity graphite, steel casting and production has reached more than 80% (but most did not use graphite mold). Isostatic graphite production line is mainly used for large-scale copper. Since 1985, China's from Austria, France, Switzerland, Japan and other countries have introduced more than 30 production lines, and domestic design and manufacture of production lines has reached more than 100, are using a graphite mold. According to statistics, in 2006 China's copper production has reached more than 360 million tons, which is mostly casting. According to the amount of graphite per ton of copper required for 2.5kg meter Qingdao graphite, the annual amount of graphite required for 486T, according to the processing yield of 70%, the annual demand for graphite blanks amount 2700T. Rapid development in recent years, there are graphite, graphite requirement recent forecast about 4000T. 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 Lacey quality graphite, graphite alleviate 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.
