| 摘要:介绍了近年来出现的纸浆磨浆机磨片新型成型工艺和表面强化方法。总结磨片的成型工艺对磨片使用寿命的影响。磨片的新型成型工艺包括磨片的整体式和复合式成型工艺。磨片的整体式成型工艺主要有覆膜铸造和数控铣削；磨片的复合式成型工艺主要是将磨齿与磨片基体分开制造,然后用镶嵌、焊接和二次铸造成型等方式将磨齿与磨片基体连接成一个整体。叙述了磨片表面强化的方法,如爆炸喷涂、火焰喷涂、激光熔覆、涂镀和激光烧结等。 |
| Abstract:There are some new techniques in the forming and surface reinforcement of pulp refiner plate recently. Firstly the influence of forming technology of refiner plate on its working life was introduced, then the new reinforcement technology was described in detail, finally the integral and composite forming technologies were elucidated. The integral forming technology mainly includes film coated casting and CNC milling. The composite forming technology includes manufacturing the bar and disk substrate separately and then fabricating the blade bar and the substrate into a whole by using the way of inlaying, welding and second casting. Meanwhile, the paper briefly introduced surface reinforcement methods for refiner plate such as explosion spraying, flame spraying, laser cladding, plating, laser sintering and so on. |
