淬火冷却是热处理工艺的重要环节,合理地选择淬火剂是保证机器零件淬火质量的重要因素。目前使用最广泛的是油基和水基液态介质,对淬火介质的基本要求是具有合适的冷却速度。因此,测定淬火介质的冷却能力就成了研究某种新介质,或了解介质在使用过程中性能变化的重要手段。评定淬火介质冷却能力常用的方法是热电偶法,它是在探头心部焊接
Quenching and cooling is an important part of the heat treatment process, a reasonable choice of quenching agent is to ensure the quality of quenching machine parts an important factor. Currently the most widely used is the oil-based and water-based liquid medium, the basic requirement of the quenching medium is to have a suitable cooling rate. Therefore, the determination of quenching medium cooling capacity has become a study of a new medium, or to understand the medium in the course of the performance of an important means. The commonly used method of assessing the cooling capacity of quench media is the thermocouple method, which is soldered on the probe heart
