What is the use of the magnetic flux trap of the quenching machine tool?

The main function of this short-circuit ring of the quenching machine tool is to place the magnetic field near the effective ring or between the two effective rings. , has a counteracting effect. The quenching machine tool manufacturer said that this device is usually applied to the ball socket heating inductor in the spherical shell, and it can change the temperature of the inner ball socket end by adjusting the distance between the interceptor and the inner ball socket end.
