Graphite chute is my company is a manufacturer of major products, mainly used ductile iron pipe centrifugal casting mouth smelting industry and other high-temperature casting mouth. is so far the best use of materials. A. The specific properties and characteristics are as follows : 1. Chute High Temperature graphite used in the graphite electrode material can be resistant to the high temperature of 2700 degrees. Centrifugal and other than metal casting solution temperature (800 ° C-1500 ° C), Because graphite crystal and good lubricity, it is the product of cold and hot state incoherent and easily cleaned advantages, thus greatly reduce the scene in labor intensity, improved labor efficiency. 2, erosion-resistant graphite material due to the density (≥ 1.56g/m3), low porosity, large compressive strength ( 1765Mpa), the thermal expansion coefficient (2.2 * 10-6 / º C), add layer of graphite crystal structure and the installation of graphite and metal solution is not between the infiltration characteristics, It made the erosion resistance properties are particularly good, can not afford to slag, thereby ensuring the purity of metal solution. for the centrifugal casting and other quality products lay a solid foundation. 3, better security, pollution-free, long service life of the product under the principles of mechanics and metal splash easy solution to the characteristics using hyperbolic shape, the chutes arc design, can effectively guarantee that the metal chute solution within smooth flow, not spatter; Because graphite is the main component of carbon, the heat will slow the oxidation and therefore will not cause pollution; As the chute graphite and high temperature erosion-resistant and therefore long life. If spheroidal graphite cast on the use, according to the specifications of ductile iron pipe, the product life table (on the basis of a number of casting manufacturers use) : B. Graphite chute in the implementation of standards, technical requirements and a physical and chemical indicators. Standards : I plant, the raw materials used to DN500 high-power graphite electrodes, the implementation of their products according to international standards GB / T 3074.4-2003. 2. Technical requirements : on-demand technology sector has provided the drawings requirements and users of the site improvements, tailor-made. 3. Physical and chemical indicators
