Embodiment 1
[0031] as attached figure 1 As shown, a multi-directional coating method uses vacuum magnetron sputtering equipment to perform multi-directional silver coating on superconducting strips, and unwinding reel 1 and unwinding reel 2 are installed on the roll-to-roll transmission device. Conductive strip material 3 is made of Hastelloy alloy, about 500 meters long, 4mm wide, and 65μm thick. Material 3, remove the winding reel 2 from the roll-to-roll transmission device and turn it over 360 degrees, and then put it back into the roll-to-roll transmission device, so that the twist of the superconducting strip 3 that appears in the above figure occurs, so The twisted part of the superconducting strip 3 is within the effective coating range 5, and the roll-to-roll transmission device pulls the superconducting strip 3 from the unwinding reel 1 to the winding reel 2 at a speed of 60 m / h. After the strip passes through the effective coating range 5 of sputtering deposition, one coating p...
Embodiment 2
[0033] as attached figure 2 As shown, a multi-directional coating method uses vacuum magnetron sputtering equipment to carry out all-round silver coating on superconducting strips. Unwinding reel 1 and unwinding reel 2 are installed on the roll-to-roll transmission device. The material 3 is made of Hastelloy, about 500 meters long, 4mm wide, and 65μm thick. It is wound on the unwinding reel 1 and drawn to the reel 2 through the roll-to-roll transmission device. In order to twist the superconducting strip, The super track strip 3 is cut at the shearing place 4 between the unwinding reel 1 and the unwinding reel 2, and the super track strip 3 on one side is twisted 360° after cutting, and then with the untwisted super track strip 3 on the other side after twisting The conductive strip 3 is welded with a DC micro-spot welding machine; the twisted part of the superconducting strip 3 is within the effective coating range 5, and the roll-to-roll transmission device unwinds the supe...
