Detailed Product Description: | Crucible and related products made of graphite forming and refractory crucible and its related products, such as crucibles, retorts, plugs and nozzles graphite milk, with a high fire resistance flatness of graphite, low thermal expansion, melting metal process by metal infiltration and erosion are also stable at high temperatures and good thermal shock resistance flatness excellent conductivity graphite prices, so the graphite crucible and its related products are widely used in the direct process of molten metal. Flake graphite manufacturing graphite conventional graphite clay crucible with carbon content greater than normally graphite flake should be greater than mesh (- sieve), and the current key improvements abroad crucible production technique is used graphite type, flake size and quality greater flexibility 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, graphite and silicon carbide crucible, large flake ingredients only content, carbon content is reduced to graphite. Pure charge subcooling large, is not conducive to the nucleation of graphite precipitation, less float. The main measures should be controlled to prevent the carbon equivalent according to the casting wall thickness; when small pieces of the wall thickness of not more than 30mm, appear critical carbon graphite floating equivalent of 4.7% - 4.9%; when the wall thickness of 30 to 100mm, appear critical carbon graphite floating equivalent of 4.5% - 4.6%; float appeared critical graphite carbon equivalent of 4.4% ~ 4.5% when the large wall thickness greater than 100mm. In particular, to control the carbon is less than 4. O%; the appropriate use of scrap, pig iron and silicon lower back with the use of charge; controlling the residual amount of rare earth is not too high; pouring temperature control; large cross section castings may be appropriate to add molybdenum or partial placement also prevents cold iron graphite float (see carbon equivalent cast iron, ductile iron). Graphite milk, the North Sea Dragon Carbon and graphite by Carbon Co., Ltd. Weifang Sea Dragon. Carbon Co., Ltd. Weifang Sea Dragon (www.longmentanye.com) Shandong Weifang, graphite and carbon products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the North Sea Dragon carbon industry leadership with the staff warmly welcome all inquiries negotiations to create the North Sea Dragon carbon industry a better future. |
