The larger the eddy current, the more significant the heating effect. By adjusting the power output power, operating frequency, induction coil design and other parameters of the medium frequency induction furnace, the eddy current size and heating effect can be adjusted to meet specific heating requirements. The medium frequency induction heating furnace 3 is a well-known technology in the art and will not be elaborated on here.

The closing plate 17 is opened by force, and at the same time, the telescopic rod 20 and the telescopic spring 21 are stretched, so that the workpiece falls out of the quenching box 7, and finally the workpiece falls on the surface of the inclined plate 22. Due to the setting of the anti-slip strip 23, the impact of the rolling of the workpiece is buffered, and the workpiece falls to the conveyor belt of the conveying assembly 2 for conveying until it enters the interior of the medium frequency induction heating furnace 3 for tempering. The tempered workpiece is taken out manually, thereby completing the quenching and tempering function of the workpiece.
