The invention relates to a rapid cooling device for a heat treatment sample, which belongs to the technical field of metal heat treatment. The device is composed of a stainless steel flange, a bottom bracket, a cooling chamber and a cooling air channel. The stainless steel flange is provided with an inlet channel and an outlet channel for connecting the gas pipelines inside and outside the heating furnace, and the bottom bracket is installed on the stainless steel flange. On, the cooling chamber is fixed on the surface of the base. During cooling, the cooling gas passes through the gas nozzles arranged symmetrically on the inner wall of the cooling chamber to uniformly cool each surface of the sample, and the cooling intensity can be adjusted to meet the experimental requirements of different samples and different heat treatment processes by adjusting the flow rate of argon gas. The rapid cooling device adopted in the present invention has adjustable cooling efficiency, is convenient for refitting and maintenance, and has high safety. It can be applied to different types of heating furnace equipment without additional modification of the equipment, which greatly improves the experimental efficiency and operability.
Description
Technical fields: [0001] The present invention relates to the field of metal heat treatment technology, in particular a rapid cooling device for heat treatment specimens. Background: [0002] Designing and developing a reasonable cooling system is an important part of the heat treatment process research. However, limited by the thermal seismic performance of the refractory materials and heating bodies of the heating furnace, the existing equipment can often only passively select one or more of the methods of slow cooling, air cooling, quenching and so on with the furnace when cooling, and the cooling rate cannot be controlled more accurately. In addition, cooling methods such as air cooling and quenching require the specimen to be transferred from the heating zone to the cooling zone and then cooled down, and the temperature drop and oxidation risk caused by the transfer process reduce the accuracy of the test results. In order to solve this problem, some researchers have chosen ...
