ZG35CrMo主动轮采用水-空气-水交替淬火代替常规油冷淬火,工件表面硬度可达320～420 HB,内孔硬度控制在280 HB以下,可达到图纸要求并保证了内孔的加工性能。
The ZG35CrMo driving wheel adopts water-air-water alternating quenching instead of conventional oil-cooling quenching. The surface hardness of the workpiece can reach 320-420 HB and the inner hole hardness can be controlled below 280 HB, which can meet the drawing requirements and ensure the processing performance of the inner hole.
