[0002] In the process of metal heat treatment, the cooling performance of quenching oil directly affects the heat treatment effect of the workpiece. Therefore, accurate testing of the cooling performance of quenching oil is an important factor in ensuring the quality of heat treatment.

[0003] Currently, IVF Smart quench testers are used to test cooling performance. The principle is to heat a cylindrical probe equipped with a thermocouple to a set temperature in a furnace, then place it in a certain volume and temperature of the test oil, record the temperature change at the core of the probe as a function of time, and then calculate the cooling rate. The existing test device has the following defects: (1) The probe must be preheated to 850℃, and then the probe tip is held and directly inserted into the test oil for testing. The operation process has certain safety hazards and is prone to injury to personnel; (2) The test oil must be heated to a specified temperature in a test container and then transferred to the test container for testing. The quenching oil temperature cannot be accurately controlled, affecting the measurement accuracy; (3) When the high-temperature probe is immersed in the test quenching oil, the quenching oil splashes violently due to the heat, affecting the safety of the operator; (4) When replacing the test quenching oil, the previous high-temperature quenching oil needs to be poured out, which is inconvenient and easy to spill, posing environmental pollution and health and safety risks.
