Abstract
This invention provides a heat treatment apparatus for an oxide superconducting wire that is easy to control atmosphere during baking and can realize a high manufacturing speed. A heat treatment apparatus () comprises a heat treating furnace () and a cylindrical rotator (), rotatable about a horizontal rotating axis, provided within the heat treating furnace (). The rotator () in its cylindrical body () have a number of through-holes () formed evenly over the whole surface of the cylindrical body (). One end of the cylindrical body () is hermetically sealed by a lid. On the other end, a gas discharge pipe () for discharging gas within the cylindrical body to the outside of the heat treating furnace () is connected to the lid. A plurality of gas supply pipes () are symmetrically provided separately from each other on the outer surface of the cylindrical body (). A number of gas jet holes are formed in each of the gas supply pipe () so as to jet atmosphere gas toward the surface of the cylindrical body. A tape-shaped wire () formed of a precursor film of a YBCO superconducting layer is wound around the rotator () for heat treatment for superconductor formation.
