[0014] The utility model has the following beneficial effects:

[0015] 1. The electromagnetic heating is performed by setting an inner cylinder, an outer cylinder, an electromagnetic coil and a clamp.

In this way, when the turntable rotates, the fixture rotates with the center of the turntable as the center, and the bottom of the workpiece on its surface always faces downward during the rotation. During the rotation, each side of the workpiece will be heated by the electromagnetic coil, thereby achieving a uniform heating effect and further improving the heating efficiency.
