Abstract

The invention relates to a pressure welding device and method for high-temperature superconducting strips. The device and the method are used for carrying out pressure welding on at least two strips.The pressure welding device is composed of one or more groups of rolling wheels arranged in different ways, wherein the core part rolling wheel adopts a non-metal elastic wheel or a metal wheel with anon-metal elastic coating layer on the surface; and on one hand, the elastic rolling compression design ensures that the resistance and the pressure borne in the whole strip width direction are uniform, and on the other hand, the design of carrying out pressure welding by the plurality of groups of rolling wheels enables stainless steel strips to be packaged continuously and reliably. Meanwhile,the invention further provides the pressure welding method. The superconducting strip manufactured by the pressure welding method and device has the beneficial effects of being low in cost, high in yield and the like; and stable preparation of the superconducting thin strip and the stainless steel packaged superconducting strip can be further realized.

Description

Technical field [0001] The invention belongs to the technical field of superconducting thin strip manufacturing, and in particular relates to a crimping device and method for high-temperature superconducting strips. Background technique [0002] Rare earth barium copper oxide REBCO (RE is Y, Gd, Sm, Nd, Dy and other rare earth elements) is a high-temperature superconducting strip with great application prospects developed in the past ten years, due to its high critical temperature and high critical current As well as better superconducting performance in a magnetic field, it can be widely used in the preparation of superconducting cables, superconducting current limiters and superconducting magnets. The existing REBCO high-temperature superconducting tapes on the market usually have two structures: superconducting thin strips encapsulated by electroplating metal layers and superconducting tapes encapsulated by bonding metal tapes. [0003] In the existing bonding metal (copper, al...
