Abstract

The invention relates to a packaging device and method for high-temperature superconducting strips, which are used for packaging at least two strips together. The packaging device is composed of one or more groups of rollers arranged in different ways, in which the core component roller is a non-metallic elastic wheel or a metal wheel with a non-metallic elastic coating on the surface. On the one hand, the elastic rolling design ensures uniform resistance and pressure in the entire strip width direction. On the other hand, the multi-set roller packaging design ensures continuous and reliable packaging of stainless steel strips. Encapsulation methods are also provided. The superconducting strip produced by the packaging method and device provided by the present invention has the beneficial effects of low cost, high yield, etc., and can also achieve stable preparation of superconducting thin strips and stainless steel encapsulated superconducting strips.

Description

technical field [0001] The invention belongs to the technical field of manufacturing superconducting thin strips, and in particular relates to a packaging 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 highly promising high-temperature superconducting tape developed in the past ten years. Because of its high critical temperature and high critical current As well as better superconducting properties 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 tapes encapsulated by electroplated metal layers and superconducting tapes encapsulated by adhesive metal tapes. [0003] In the existing adhesive-clad metal (copper, al...
