Bolt for the production of superconductive semi-finished material

摘要

A bolt is proposed for the production of superconductive semi-finished material, which bolt has a matrix material body (which is provided with holes) as well as rods (3) which are inserted into the holes and consist of superconductive material or material which is converted into superconductive material in the course of the production process, the matrix material body being composed, according to the invention, of stacked, perforated discs (2). This avoids the problem of drilling deep holes which otherwise occurs. <IMAGE>
