The method for manually cooling the sample by water adopted at present has more defects, such as: 1. when the temperature of a steel sample is higher, the sample cannot be chilled, and brittle failure is easily caused. 2. The chilling time and temperature can be mastered by operators with abundant experience, and the operators are not easy to master by novices. 3. The manual chilling is adopted and is carried out after the natural cooling is carried out to a certain temperature, and the waiting time is longer. The artificial chilling method is adopted to rapidly reduce the temperature to the test temperature, lath martensite is easily formed in the continuous chilling process, the amount of the martensite is continuously increased along with the reduction of the temperature, the yield strength is obviously higher than that in a natural cooling state due to the increase of the traveling nucleus of the martensite in the cooling process, and the cooling speed and the cooling time have certain influence on the formation of the martensite, so that an approximate performance is obtained in the artificial chilling mode to guide the adjustment and the control of the process, and therefore, the rapid cooling device for the steel sample is provided.
