| 摘 要： | 研究了淬硬钢回火硬度与回火温度的关系．建立了回火硬度与回火温度关系的回火效应模型。磨削热导致回火引起淬硬钢磨削后表面硬度变化。通过合并磨削热模型和回火效应，可以预测工件磨削后的表面硬度变化。进行了45^#钢的高速磨削试验．研究了工件速度和磨削深度对磨削后表面硬度的影响。试验值与预测值能够较好吻合。

| Abstract: | Having studied the relationship between tempered hardness and tempering temperature for hardened carbon steels, a tempering behaviour model is set up between hardness and temperature. Tempering by grinding heat causes hardness change at the surface of the hardened steels. Combining the tempering behaviour with the thermal model of grinding, the change in surface hardness due to grinding heat can be predicted. Experiments of grinding 45 steel were carried out. The effects of grinding speed and grinding depth on surface hardness are studied. The predicted values agree fairly well with the experimental results. |
