[0005] At present, there is no good solution to the influence of the steam film on the quenching process in the above quenching process. The introduction of electrolytes, increasing the surface roughness of the workpiece or reducing the size of the workpiece are the methods to eliminate the steam film so far.
And most of them use the method of spraying water during the quenching process of the steel pipe, but this method does not form a closed-loop control and cannot effectively remove the steam film

Abstract
A device and method for eliminating steam film, comprising a support platform, a coil connection plate, a temperature measurement camera, an induction coil, a nozzle, a steel pipe, a cooling water sprayer, a rotating platform device, a lifting device, a water pipe A, a water pipe B, a water pump, Console, water storage tank, working platform and induction switch; during the induction heating quenching process of the steel pipe provided by this device, a closed-loop system is formed by the system, temperature measurement camera, water pump, water sprayer and steel pipe quenching device, real-time Monitor the temperature of the steel pipe quenching process to determine the degree of elimination of the steam film during the quenching process, and control and adjust the water pump by the console to control the water pressure and water volume sprayed by the nozzle, so as to achieve the purpose of removing the steam film generated during the quenching process . The steel pipe is fixed on the rotating platform, and the two are placed on the lifting device, which can ensure that the steam film on various parts of the inner wall of the steel pipe can be eliminated during the quenching process.
Description
technical field [0001] The invention belongs to the technical field of metal heat treatment processing, and in particular relates to a device and a method for eliminating steam film. Background technique [0002] Quenching is an important heat treatment method in metal heat treatment. It means that when it is just heated above the critical temperature, it is kept for a period of time on this basis, and then cooled at a rate greater than the critical cooling rate to obtain martensite-based A heat treatment method for unbalanced tissues. Thereby improving the mechanical properties of the workpiece or material - strength, stiffness, wear resistance. [0003] There are three stages in the quenching process: steam film stage, boiling stage and convection stage. The steam film stage refers to the moment when the rigid part or material enters the medium. At this time, the medium around the rigid part is vaporized immediately, forming a layer of steam film on the workpiece. With t...
