Abstract
A method of manufacturing a superconducting wire includes the step of drawing a wire formed by coating raw material powder for a superconductor with a metal or a wire with a multifilamentary structure, the step of sealing an end portion of a clad wire or a multifilamentary wire after the step of drawing, and the step of first rolling, rolling the multifilamentary wire after the step of sealing. With this method, a superconducting wire having high and uniform performance can be obtained.
Claims6
A method of manufacturing a superconducting wire, comprising the steps of:
- drawing a wire formed by coating raw material powder for a superconductor with a metal,
- sealing an end portion of said wire after said step of drawing, and
- rolling said wire after said step of sealing.
A method of manufacturing a superconducting wire, comprising the steps of:
- drawing a wire formed by coating raw material powder for a superconductor with a metal n times (n is an integer satisfying n≧2),
- rolling said wire after said step of drawing said wire n times, and
- sealing an end portion of said wire in at least one of an interval between the step of k-th (k is an integer satisfying n−1≧k≧1) drawing in said step of drawing said wire n times and the step of (k+1)-th drawing in said step of drawing said wire n times and an interval between the step of n-th drawing in said step of drawing said wire n times and said step of rolling.
