PROCESS FOR ASSEMBLING COMPOSITE BILLETS FOR THE MANUFACTURE OF MULTIFILAMENTARY SUPERCONDUCTING STRANDS.

摘要

The invention relates to a method for assembling composite billets (2) with a circular section for producing multifilamentary superconducting wires in which a cylindrical body (1) is filled with elementary polygonal rods (6) based on metal or metal alloys, BR/ characterized in that toolbars (3, 4, 5) having at least one axis of symmetry of order n (integer) are stacked in the cylindrical body (1) positive greater than or equal to 2) and then remove these bars (3, 4, 5) by replacing each bar by a bar consisting of elementary rods (6) stacked in an orderly and compact manner to have a minimum footprint each bar (3 ', 4 ', 5') having the same section as the bar (3, 4, 5) it replaces. BR/ Preferably the sections of the bars (3, 4, 5) are rectangular or square and the bars (3 ', 4', 5 ') which replace them consist of elementary rods (6) rectangular or square. BR/. Speed and ease of assembly. / P
