The graphite material has the characteristics of ablation resistance, thermal shock resistance and so on. It is used in the long tail nozzle of air to air missile, and is the main material for the structural parts of the engine throat. The requirements of the parts size and appearance of high technology, but because of its special material, cutting performance, processing quality, especially in the easy processing of edge collapse defects, these have become a bottleneck of non metal processing. In recent years, various types of engines, long tail nozzle, graphite parts processing tasks heavy, high technical requirements. Based on the analysis of the scrap graphite parts for the past year, it is found that the scrap produced by the…
The carbon / carbon composites(we also named it as C-C composite or carbon-carbon composite material) is the carbon fiber and its fabric reinforced carbon matrix composites. It is one of the few alternative materials currently used in more than 1650 °C, the highest theory temperature is higher than 2600 °C , so it is considered to be one of the most future development of high temperature materials with low density (<2.0g/cm3), high strength, high modulus, high thermal conductivity, low thermal expansion coefficient, good friction performance, and good thermal shock resistance, dimensional stability, etc., Carbon carbon composite can be used for Vacuum Furnace, High Temperature Sintering Furnace, Solar Silicon Furnace, crystal growth furnace, inert atmosphere furnaces, semiconductor furnace, multicrystalline Directional Solidification…
Graphite electrode is mainly made from petroleum coke and needle coke an make the coal tar pitch as the binder, through calcination, mixing, kneading, pressing, baking, graphitization, and machining , it is a conductor in an electric arc furnace to form arc release electricity for heating and melting of the charge, it can be divided into ordinary power, high power and ultra high power according to the quality index level. The graphite electrode mainly includes ordinary power graphite electrode, oxidation resistant coating, graphite electrode, high power graphite electrode and ultra high power graphite electrode . In order to make the graphite electrode with a series of physical and chemical properties when we used it , the asphalt binder decomposition and…
