Recently, the 36 MN aluminum-matrix ceramic powder composite extruder introduced by China`s leading aluminum-matrix silicon carbide ceramic composite technology Corporation: AHYL was successfully put into production, breaking the extrusion equipment and extrusion process of aluminum-based ceramic powder composites. The monopoly of major nuclear industry countries such as Europe and the United States has reduced the production costs of similar products in China, and at the same time promoted the technological progress of China's high-performance metal-matrix ceramic composite extrusion equipment and extrusion technology.
This equipment is mainly used for the production of aluminum-based ceramic composite protective panels for nuclear reactors. At present, it has produced two batches of qualified products for nuclear reactors for National Nuclear Power. The extrusion production of ingots uses powder sintered materials. The boron carbide in the ingots is also known as black diamonds. The hardness is second only to diamond in nature. The sintered ingots are very sensitive to the extrusion temperature and extrusion speed, and are sensitive to the mold Because of the great wear and tear, the Chinese R&D team has established a precise extrusion temperature and extrusion speed control system. For the first time, the online mold heating system has been used to improve the accuracy of the extrusion barrel temperature control. At the same time, the project has also applied a number of China Heavy Industry Research Institute Innovative technology independently researched and developed.
