Graphite used in the industry very wide, almost every industry are used. Industrial multi-use artificial graphite, which is the specialty graphite. Its shape can be divided into the following way. 1. Isostatic graphite. That is a lot of people called the three high graphite, but not three high is isostatic pressing. 2. 3 molded graphite. Extruded graphite graphite, the electrode material. Which according to the particle size of the graphite graphite production, but also can be divided into: the details of the graphite structure, coarse graphite (particle size in general about 0.8mm), there is a graphite electrode (2-4mm). Burden pure graphite wholesale large degree of supercooling, is not conducive to the nucleation of graphite graphite precipitation quality, floating less. 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). BN: a high temperature resistance, excellent corrosion resistance, high thermal conductivity, high insulation, lubrication properties of materials. Can be widely used in petroleum, chemical, machinery, electronics, power, textile, nuclear industry, aerospace and other industrial sectors. Can be used as high-voltage and high-frequency plasma arc electric insulator, a semiconductor doped solid phase materials, structural materials of the nuclear reactor, the neutron irradiation of the release agent to prevent the packaging material, and the model of the high-temperature lubricant, antioxidant or anti-water grease. Boron nitride powder can also be used as the release agent glass beads, glass and metal forming the release agent. Superhard materials made from boron nitride process, can be made into high-speed cutting tools and geological exploration, oil drilling drill.
