Description

technical field [0001] The invention relates to the technical field of superconducting strip preparation, in particular to a multilayer YBCO superconducting strip stripping device and a stripping method thereof. Background technique [0002] As the second type of high-temperature superconducting wire, YBCO superconducting tape is widely used in superconducting magnets, superconducting cables and other fields due to its high current-carrying characteristics. With the continuous improvement of the current-carrying performance of superconducting tapes, various means of improving the current-carrying capacity of superconducting tapes have been born; including the method of superconducting superconducting layers to obtain YBCO tapes with high current-carrying capacity. The specific principle of its implementation is mainly: align the YBCO superconducting layers face to face, heat treatment after applying a certain pressure, melt and weld the silver layers together, and then peel ...

AI Technical Summary

Problems solved by technology

The peeling method in the prior art is the method of manual peeling, and the existing problems are: it is difficult to control the radius of manual peeling; it is difficult to control the strength in the process of manual peeling; the speed of manual peeling is unstable

The above problems lead to incomplete peeling of the YBCO layer during the peeling process, and there are often breakpoints and discontinuous lines, which will affect the performance of the multilayer YBCO strip, and this shortcoming will become more and more obvious with the increase of the strip length, which is not conducive to Preparation of multilayer YBCO long strips
