Abstract
A process is disclosed for producing a strip-shaped superconductor with several conductor cores made of a high-T superconducting material and surrounded by a normal conducting material. A conductor blank ( ) produced from a fabricated conductor should be rolled flat at least once. For that purpose, the conductor blank is fed into the gap ( ) between two rollers ( ) of which the rolling surfaces ( ) describe a concave, at least approximately elliptical contour at least in the rolling region ( ). The strip-shaped multi-core conductor produced in this way advantageously contains superconducting cores made of a bi-cuprate embedded in an Ag matrix.
