The Chinese domestic price of graphite electrodes is in a rising trend currently. The Deputy Secretary General Liu Ronghua from China Non-Metallic Materials Industry Association graphite Specialized Committee said: “ Due to shortage of supply side, graphite prices or continuous phenomenon. " “ the main reasons are the impact of environmental protection factors, many enterprises stop production, coupled with the electrode production cycle is relatively long, at least 3 months or more, so the market is in short supply, some enterprises have money but will not take delivery.". Before the sale of goods, the money can not be received, and now is the seller's market, it must have the dvance money." This year, affected by environmental inspectors, the graphite electrode…
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…
