Ferrous metallurgy casting graphite mold: To shorten the production process Lacey graphite prices, lower end of the cost, 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, our country from Austria, France, Switzerland, Japan and other countries have introduced more than 30 production lines of graphite, while the domestic design and manufacture of the production line 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 of Lacey graphite, which is mostly casting. According to the amount of graphite per ton of copper required for 2.5kg dollars, 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 have predicted the recent requirement in graphite is about 4000T. The main role of carbon graphite felt after felt under vacuum or inert atmosphere by more than 2000 ℃ high temperature treatment of graphite felt, carbon content than the carbon felt high, reaching more than 99%. The late 1960s the world has graphite felt the supply of goods. Graphite felt due to the choice of different raw mat into PAN-based graphite felt and glue-based graphite felt two. The PAN-based carbon fiber felt or rayon-based carbon felt cut to the desired size, rolled into a tubular graphite into the material of the container, the container placed in a high temperature furnace graphite (graphite tube furnace for high temperature furnace, IF, high frequency induction furnace or other heating forms of high-temperature furnace), with a vacuum or inert gas through high purity, to 100 ~ 300 ℃ / h heating rate of heating to 2200 ~ 2500 ℃ graphite sell, then that is naturally cooled to 100 ℃ too. Nature there are no pure graphite, which often contain SiO2, Al2O3, FeO, CaO, P2O5, CuO and other impurities. These impurities often appear to quartz, pyrite, carbonate and other minerals form. In addition, water, bitumen, CO2, H2, CH4, N2 and other gases portions. Therefore, the analysis of graphite, in addition to the fixed carbon content was measured, it must also determine the content of volatile matter and ash at the same time.
