METHOD FOR MANUFACTURING A HIGH-TC SUPERCONDUCTING TAPE, AND DEVICE FOR IMPLEMENTING SAME

摘要

P This process aims to manufacture a superconductive tape in superconductive material at high critical temperature. A starting conductor (4a) consisting of the conductive pre-product must be subjected to a flattening operation with at least two successive rolling steps, providing for the second rolling step of the rolls (W1, W1 ') of which the direction of rotation is opposite to the direction (r1, r1 ') of rotation of the rolls (W1, W1') for the preceding rolling step, so that the direction (v1) of rolling is reversed. The corresponding rolling device (2) has at least one pair (P1) of cylinders, an adjustable grip (3) for passing the starting conductor (4a), as well as means for reversing the direction (r1, r1 ') of rotation. /P
