| 摘 要： | 在用标准测试仪检测淬火介质冷却特性的同时,用摄像机摄录了探棒周围的状况.对比发现,按测得的冷却特性曲线的形状划分的冷却阶段,与探棒表面实际发生的冷却情况大不相同.说明了产生这种差异的原因.通过分析和推理,得出了结论:不能从淬火介质的冷却特性曲线去划分探棒所处的冷却阶段;凭测出的冷却特性曲线不可能准确推算实际工件可能获得的冷却情况;淬火介质的冷却特性曲线只宜用在介质冷却特性的相互对比中.

| Abstract: | The visual phenomena occurred around the quench probe were recorded with digital video camera during standard test of quenching media. It was found that partition of cooling process according to the measured cooling rate curve is not totally corresponding to what were visually observed. The reasons of this discrepancy are discussed. It is concluded the cooling process of actual quenched parts can not be accurately predicted by merely using the measured coding rate curves of quenching media, which are only applicable for comparison of characteristics of different quenching media. |
