本文介绍淬火介质性能的一种新的测试方法。测试系统是由奥氏体不锈钢制成的探头和微机组成。在探头的几何心部有一个热电偶,探头在炉内加热到指定的温度850℃后,迅速转移到固定体积的待测介质中,与此同时用微机采集探头温度随时间的变化。我们测量了水和油两种介质中温度—时间数据。这种方法提供了淬火介质冷却特性的所有可能收集到的信息。 This article describes a new test method for quenchant properties. The test system consists of a probe made of austenitic stainless steel and a microcomputer. In the geometric center of the probe has a thermocouple, the probe in the furnace heated to a specified temperature of 850 ℃, quickly transferred to a fixed volume of the medium to be measured, at the same time with the computer acquisition of the probe temperature over time. We measured temperature-time data in both water and oil media. This method provides all possible information collected on quench media cooling characteristics.
