PROCESS FOR MANUFACTURING A MULTIFILAMENTARY STRAND BASED ON SUPERCONDUCTING OXIDES AND STRAND OBTAINED BY THIS PROCESS.

摘要

P Process for the production of a multifilament strand (100) based on superconducting oxides, the process in which the following operations are carried out: BR/ - a "stage O" is produced by introducing a powder of the said oxides, into a metal tube (3) of rectangular or square section, this tube undergoes a mechanical transformation to reduce its transverse dimensions while maintaining its profile, and it is cut into short stems, BR/ - a "stage 1" by, juxtaposing said short rods in a metal container (5) of rectangular transverse profile, and performs the same mechanical transformation and the same cutting as for said "stage O", BR/ - it realizes "stages 2, 3 ... n", as said "stage 1", BR/ - heat is treated "stage n" to sinter said powder. / P
