Verfahren zum Assemblieren zusammengesetzter Stränge zur Herstellung von multifilamentären supraleitenden Drähten

摘要

The invention relates to a procedure for assembling composite billets (2) of circular cross-section for the manufacture of multifilamentary superconducting wires, in which a cylindrical body (1) is filled with elementary polygonal bars (6) based on metal alloys or made of metal, characterised in that tooling rails (3, 4, 5) possessing at least one axis of symmetry of order n (a positive integer greater than or equal to 2) are stacked inside the cylindrical body (1), these rails (3, 4, 5) are then removed, replacing each rail by a rod consisting of elementary bars (6) stacked in an ordered and compact fashion so as to have minimum proportions, each rod (3', 4', 5') having the same cross-section as the rail (3, 4, 5) which it replaces. Preferably, the cross-sections of the rails (3, 4, 5) are rectangular or square and the rods (3', 4', 5') which replace them consist of elementary rectangular or square bars (6). Speed and ease of assembly.
