淬火质量的好坏与加热愠度、加热时间密切相关。而加热时间在正常淬火温度的前提下是根据工件的有效壁厚来确定的。在盐浴炉中加热,推力球轴承垫圈竖着串放,如图1所示。根据有关资料介绍,零件的有效壁厚如图2所示。我厂多年来按此有效厚度确定加热时间,产品质量稳定。 Quenching quality is good or bad and heating 愠 degrees, heating time is closely related. The heating time under the premise of the normal quenching temperature is based on the effective wall thickness of the workpiece to determine. In the salt bath furnace heating, thrust ball bearings washer vertical string, as shown in Figure 1. According to the information introduced, the effective wall thickness of the part shown in Figure 2. I plant over the years to determine the effective thickness of the heating time, product quality and stability.
