Problems solved by technology

However, when using pipes, the efficiency is low because continuous processes cannot be adopted, and when forming pipes, it is necessary to have equipment and processes similar to those required for manufacturing superconducting core wires. Therefore, due to the increased Plastic processing and heat treatment process, so the critical current characteristics will be lowered, and there are disadvantages in terms of manufacturing efficiency and cost.

Abstract

The invention relates to manufacture method of superconductive wire material, especially relating to improved manufacture method for superconductive wire material based on existing CTFF method. In the method, stabilized material is continuously acquired at low cost for guaranteeing high critical current and magnetic property without plasticizing processing for long line MgB<2> superconductive wire; and plasticizing processing for averaging the critical current density is accomplished at low cost for manufacturing MgB<2> superconductive single core wire and multi-core wire especially manufacturing highly dense MgB <2> superconductive wire. In the invention, joint welding enables superconductive powder not regenerate and conductor can be electroplated, so the working procedure of inserting the stabilized material into tubing or forming tubing can be omitted, long line superconductive wire can be continuously manufactured at low cost, MgB<2> superconductive wire industrialization is accomplished in advance.
