The utility model has a simple structure and is easy to operate. It only transforms a full-ring inductor into two half-ring inductors, maintaining the high efficiency and good economy of the original solution, and does not require a turning mechanism, reducing the complexity of the equipment and the waiting time for turning, and can perform cooling operations while heating, saving time.

[0004] However, there are still some shortcomings in the above scheme. At present, the surface quenching of small-tonnage guide wheels is carried out by heating one side first, and then rotating the guide wheel 180° for secondary heating. During the second heating of the other side, the wheel edge after the first quenching will be annealed due to heat conduction, and the hardness will be reduced, which cannot meet the hardness value required by the heat treatment technology.

[0005] In view of this, the utility model proposes a guide wheel quenching device. Utility Model Content
