Embodiment Construction

[0036] As mentioned in the background technology, the deficiencies of the prior art are mainly reflected in: the main magnet structure in the existing superconducting DC induction heating technology can only heat a limited one or two workpieces at the same time; the utilization rate of the superconducting magnet is low, and its The advantage of strong magnetic field is not fully reflected in the superconducting induction heating technology; when the superconducting induction heating main magnet is heating the workpiece, excessive radiation and heat leakage caused by convection occupy the time within the heating cycle.

[0037] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embod...
