Method of and apparatus for manufacturing tape-formed oxide superconductor

In an apparatus for manufacturing a superconductor by heating and reacting a tape-formed wire material in which a film body being a superconductor preform is formed on a surface of a tape-formed substrate;

• an apparatus for manufacturing a tape-formed oxide superconductor, comprising:
• (a) a tubular furnace in which the tape-formed wire material travels continuously;
• (b) a gas supply port which serves to supply a reactive gas vertically to a film surface of the film body in said tubular furnace;
• and
• (c) gas discharge ports which serve to discharge a gas after the reaction, from both sides of the film surface along the film surface.

• an apparatus for manufacturing a tape-formed oxide superconductor, an apparatus for manufacturing a tape-formed oxide superconductor, comprising:
• (a) a tubular furnace in which the tape-formed wire material travels continuously;
• (b) a pair of reels which are disposed within said tubular furnace in order to extend the tape-formed wire material therebetween;
• (c) a plurality of gas supply ports which are provided along a traveling direction of the tape-formed wire material in order to supply a reactive gas vertically to film surfaces of the respective film bodies of the tape-formed wire material extended and traveling between said pair of reels;
• and
• (d) a plurality of gas discharge ports which are provided on both sides along the film surfaces in order to discharge a gas after the reaction, from over the film surfaces in correspondence with said gas supply ports.
