摆线板零件材料为GCr15,要求热处理硬度HRC 58～62,脱碳层深度小于0.10mm。我们经过多次试验,在R J X-75-9箱式电阻炉中加热,采用工件表面涂抹法和罩式容器密封法相结合,有效地防止了工件表面产生氧化脱碳。淬火前,先将工件加热到200℃左右,然后,立即均匀地涂刷一层过饱和硼酸(H_3BO_3)酒精溶液,待酒精挥发后,将工件装入罩式容
The material of cycloid plate is GCr15, the hardness of HRC 58 ~ 62 is required for heat treatment, and the depth of decarburized layer is less than 0.10mm. After several tests, we heated it in the R J X-75-9 box-type resistance furnace and adopted the combination of the surface coating method of the workpiece and the bell-type container sealing method to effectively prevent the oxidation and decarbonization of the workpiece surface. Before quenching, first the workpiece is heated to about 200 ℃, then, immediately and evenly brushing a layer of saturated solution of boric acid (H_3BO_3) alcohol solution, until the alcohol is evaporated, the workpiece into the hood capacity
