Abstract

The invention discloses a method for manufacturing a superconducting magnet for a high-temperature superconducting maglev train. The method is as follows: A. coating a curing agent on the surface of a high-temperature superconducting strip (1); The strip (1) is wound from the inside to the outside to form a hollow ring or a solid round cake, and the inner end (1a) of the strip (1) is exposed; B, the inner end (1a) of the high-temperature superconducting strip (1) is The end (1a) and the outer end (1b) of the high-temperature superconducting strip (1) are connected to form a superconducting joint (2), forming a closed superconducting ring or superconducting cake. The superconducting magnet manufactured by the method has a high critical current density, and the concentrated magnetic field lines in the area above the magnetic track can enter the superconducting magnet densely and intensively to be pinned together, and the resulting levitation force and guiding force are strong.
