Description

Technical field [0001] The invention relates to a winding device for preparing superconducting tapes and integrating coating and heat treatment processes. Background technique [0002] High-temperature superconducting tape is a superconducting tape that has been developed in recent years and has great application prospects. It is widely used in superconducting current limiters, nuclear magnetic resonance, superconducting magnets and power cables, military industry and other industries. The typical structure of the second-generation high-temperature superconducting tape is composed of four major structures: metal base tape, buffer layer, superconducting layer, and stabilizing layer. Each layer is prepared by many complicated processes, and each layer will be unqualified. It has a great impact on the performance of the superconducting tape. [0003] The function of the stabilizing layer is to protect the superconducting film and introduce current into the superconducting layer. It ...

AI Technical Summary

Problems solved by technology

In such a long pipeline, the strip material sags seriously due to the influence of gravity, which is easy to deform the strip material and cause damage to the strip material. In addition, because the length of the tube annealing furnace is too long and the volume is large, the tube furnace needs to be cleaned before annealing. Vacuumize the excess water vapor and then pass oxygen into the equipment to ensure the oxygen concentration in the annealing equipment, the efficiency is low

It takes more than ten hours, and the production cost and efficiency are very low
