Embodiment 1

[0020] Such as figure 1 As shown, a group of steering devices A1 and A1* and guide devices B1 and B1*, B2 and B2* of the present invention are installed on both sides of the opening outside the uniform temperature zone of the furnace according to the design requirements to ensure that the Ni-5at.% to be annealed The long base tapes of W alloy do not touch each other during tape running.

[0021] In order to achieve a comparative effect, this embodiment still uses the parameters of the case in the background technology, that is, the length of the uniform temperature zone is 0.9m, and the dynamic annealing of the 100m-long baseband is completed, and the process parameters are 1100°C for 3 hours. Due to the use of a set of steering devices, it is equivalent to the three-thread online dynamic annealing of the long base belt at the same time, so the belt running speed is 0.9m / h, that is, it takes 1 hour to enter and exit the uniform temperature zone once, and a total of 3 times to ...

Embodiment 2

[0024] Such as figure 2 As shown, the two sets of steering devices A1 and A1*, A2 and A2* and guide devices B1 and B1*, B2, B3, B4 and B4* of the present invention are installed on both sides of the opening outside the uniform temperature zone of the furnace according to the design requirements. It is ensured that the long base bands of the Ni-5at.%W alloy to be annealed do not contact each other during the band travel.

[0025] Similar to Embodiment 1, this embodiment still adopts various parameters of the case in the background technology to achieve a comparative effect. Due to the use of two sets of steering devices, it is equivalent to five threads of the long baseband being dynamically annealed online at the same time, and the tape running speed is 1.5m / h, that is, it takes 0.6h to enter and exit the uniform temperature zone once, and a total of 5 times to enter and exit can reach The process requirement of heat preservation for 3h. Still ignoring the heating and cooli...

Abstract

The invention discloses an auxiliary device used for perfecting online dynamic annealing of a long baseband for a coated conductor and an implementation method, which belongs to the field of superconducting material preparation. The device is composed of a steering device and a guide device which are arranged on the two open sides of a hearth, wherein the steering device comprises at least a pair of fixed pulleys used for changing the band walking direction of the long baseband in the hearth; the guide device is composed of at least two pairs of fixed pulleys used for limiting the position of the long baseband in the band walking process. A long baseband to be annealed is discharged from a band discharge wheel and is wound on the steering device and the guide device by a guide band and is finally folded on a band folding wheel on the other end of the hearth; in an annealing process, the long baseband is guided by the guide band to pass in and out from the hearth for multiple times according to a band walking route and leave the hearth after meeting the process parameter requirements of complete recrystallization to be rounded on the band folding wheel, and the whole process is continuously implemented. The device is installed on an existing device to improve the space utilization rate of the hearth, reduce the heat treatment time of the long baseband, save the energy source and protective atmosphere and reduce the cost.

Description

technical field [0001] The invention provides an auxiliary device for improving long baseband on-line dynamic annealing for coated conductors and a realization method thereof, belonging to the technical field of material preparation equipment. Background technique [0002] With the rapid development of superconducting technology, the demand for superconducting materials in the application field is increasing, and the production and preparation of superconducting wire strips are about to enter the process of industrialization. Take YBCO (YBa 2 Cu 3 o 7-x ) represented by the second-generation high-temperature superconductors are considered to be the most promising superconducting materials for large-scale applications. Since YBCO is a ceramic phase superconductor, it needs to be coated on a textured metal ductile substrate to achieve large-scale application, and the connection cost of the superconducting wire strip at the joint is very high, so the rolling-assisted biaxial...
