| 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. |
