Graphite products environmental health, no radioactive contamination, high temperature. Carbon to go through at 2000-3300 degree heat at least a dozen environmental circadian graphitization process in order to become graphite, therefore, graphite release of hazardous substances already exhausted, at least within 2000 degrees is stable. Crucible and related products made of graphite forming and refractory crucible and its related products, such as crucibles, retorts, plugs and nozzles, etc., with a high fire resistance, low thermal expansion, melting metal process by metal infiltration and When erosion is also stable, good thermal shock resistance at high temperatures and excellent conductivity, so the graphite crucible and its related products are widely used in the process of direct molten metal. The traditional graphite clay crucible with flake graphite manufacturing carbon content greater than usually graphite flake should be greater than mesh (- sieve) graphite manufacturers, and now the important improvements abroad in the crucible of production technology in graphite prices, the graphite type with scales size With greater flexibility and quality followed by silicon carbide graphite crucible to replace the traditional clay graphite crucible, which is constant with the introduction of the steel industry in technology generated. Constant voltage technology can also be applied to make a small flake graphite, clay graphite crucible, and in manufacturing, silicon carbide content graphite crucible large flake graphite component only, the carbon content is reduced to graphite. 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 graphite, our country from Austria, France, Switzerland, Japan and other countries have introduced more than 30 production lines, and 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, 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. Qingdao graphite | Graphite | Sea Dragon by Carbon Carbon Co., Ltd. Weifang Sea Dragon.
