Title:
HEAT TREATMENT APPARATUS FOR OXIDE SUPERCONDUCTING WIRE
Document Type and Number:
WIPO Patent Application WO/2007/080875
Kind Code:
A1
Abstract:
This invention provides a heat treatment apparatus for an oxide superconducting
wire that is easy to control atmosphere during firing and can realize a high manufacturing
speed. A heat treatment apparatus (1) comprises a heat treating furnace (4) and
a cylindrical rotator (5), rotatable about a horizontal rotating shaft, provided
within the heat treating furnace (4). The rotator (5) in its cylindrical body
(5a) have a number of throughholes (5b) formed evenly over the whole surface of
the cylindrical body (5a). One end of the cylindrical body (5a) is hermetically
sealed by a lid. On the other end, a gas discharge pipe (7) for discharging gas within
the cylindrical body to the outside of the heat treating furnace (4) is connected
to the lid. A plurality of gas supply pipes (8) are symmetrically provided separately
from each other on the outer surface of the cylindrical body (5a). A number of gas
jet holes are formed in each of the gas supply pipes (8) so as to jet atmosphere gas
toward the surface of the cylindrical body. A tape-shaped wire (6) formed of a
precursor film of a YBCO superconducting layer is wound around the rotator (5)
for heat treatment for superconductor formation.
