Embodiment Construction
[0014] The present invention will be described in detail below through preferred embodiments in conjunction with the accompanying drawings.
[0015] Arrange the device of the present invention in a staggered manner on the upper and lower work rolls of the strip, replace the staggered backup rolls in the prior art, and support them in a staggered manner; as figure 1 As shown, the outer cylinder 3, the left and right annular end caps 4, 4' and the inner cylinder 5 are assembled into an annular cavity 8, and the 3D printing space support structure 7 is loaded into the annular cavity 8, and the 3D printing space support 7 It is a space truss structure printed by a 3D printer to ensure a reasonable supporting effect. The annular cavity 8 is evacuated through the vacuum check valve 1 to achieve a heat-resistant vacuum environment. A superconducting outer rotor motor stator and outer rotor form a superconducting The magnetic levitation structure, by controlling the stator current of ...
