Title:
APPARATUS FOR MANUFACTURING OXIDE SUPERCONDUCTING WIRE AND METHOD FOR MANUFACTURING OXIDE SUPERCONDUCTING WIRE
Document Type and Number:
Japanese Patent JP2015225728
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide technology capable of improving manufacturing efficiency of an oxide superconducting wire by carrying out a treatment of exposing an oxide superconducting layer to an atmospheric gas in a short time in a treatment chamber, such as an oxygen introduction treatment to an oxide superconducting layer or a calcination treatment and a firing treatment in an MOD (metal organic deposition) method upon manufacturing an oxide superconducting wire.SOLUTION: An apparatus for manufacturing an oxide superconducting wire is provided for manufacturing an oxide superconducting wire by subjecting a long oxide superconducting wire wound on a reel to an exposure treatment to a predetermined atmospheric gas. The apparatus includes: a container formed into a cylindrical shape having an inner diameter approximately equal to an outer diameter of the reel, and configured to accommodate the reel in such a way that the inner circumference of the container is in contact with an outer circumference of the reel, thereby to form spaces interposing the reel; and a pressure control mechanism for controlling a pressure of each space in such a way that when an atmospheric gas is supplied to the container, a difference is induced between pressures of the spaces formed to interpose the reel.
