Description
Technical Field
The invention belongs to the technical field of superconducting material preparation, and relates to a preparation method of a superconducting wire with a short production period and an ultralow copper ratio.
Background
The NbTi/Cu superconducting wire has the advantages of good processing characteristics, stable superconducting performance, lower price and the like, and is widely applied to superconducting magnets. With the development of superconducting technologies such as magnetic concentrator, magnetic Resonance (MRI) and Nuclear Magnetic Resonance (NMR), there is an increasing demand for niobium-titanium superconducting materials with short production cycle, low copper ratio and high critical current density.
The traditional preparation process of the niobium-titanium superconducting wire is to prepare a single core rod firstly, then assemble the single core rod into a composite ingot, and twist the composite wire to reduce loss. CN103367937B discloses a method for preparing a multi-core wire joint of an NbTi superconductor, which penetrates into a superconducting composite tube and an NbTi superconducting wire cluster after being twisted by mixing with each other. Because the copper cladding is adopted by the composite ingot, the copper ratio of the superconducting wire prepared by the method is generally more than or equal to 0.5, the production period is extremely long, and the requirements of ultralow copper ratio (< 0.5), high-current superconducting wire and short period of superconducting magnet can not be met.
Disclosure of Invention
The invention aims to solve the problems that the ultralow copper ratio (< 0.5) which cannot meet the requirements of a superconducting magnet, the density of the superconducting wire is low and the production period is long when the superconducting wire is twisted during the preparation of the niobium-titanium superconducting wire to reduce the loss.
Thus, the present invention provides a method of preparing ultra-low copper ratio superconducting wires with a short production cycle to meet this need in the art.
In one aspect, the invention relates to a method for preparing a short-production-period ultralow-copper-ratio superconducting wire, which comprises the following steps: preparing a single-core wire with ultra-low copper ratio;
carrying out stranding on the ultra-low copper ratio single-core wire;
the strand number of the twisted cable ranges from 7 to 20000 strands;
the cables are multi-stage cables, and the directions of the cables at each stage are consistent. Specifically, the multi-stage cable is not lower than the secondary cable. In order to prevent energy loss between core wires, unlike the back twisting of conventional multi-stage cables, the preparation method has the advantages that each stage of cable is uniform in direction during cable twisting, and the multi-stage cables are simultaneously rotated right-hand or simultaneously rotated left-hand.
Furthermore, in the preparation method of the superconducting wire with the short production period and ultra-low copper ratio, the pitch of the stranded cable is 5-100 mm. The pitch of the cable cannot be too large, if the pitch is too large, the strands are loose, the size fluctuation is large, and the cable is not easy to use.
Further, in the preparation method of the short-production-period ultralow-copper-ratio superconducting wire, the preparation method of the ultralow-copper-ratio single-core wire comprises the following steps: filling an Nb Ti rod into an Nb tube, filling the Nb Ti rod wrapped with the Nb tube into a Cu tube, vacuumizing, and sealing and welding an upper cover and a lower cover to form an NbTi/Nb/Cu primary single-core ingot;
and extruding, peeling, stretching and heat treating the NbTi/Nb/Cu primary single-core ingot to obtain the ultralow copper ratio single-core wire. The invention peels off the single-core ingot during stretching, so that the copper ratio is further reduced.
Furthermore, in the preparation method of the short-production-period ultralow-copper-ratio superconducting wire, the copper ratio of the ultralow-copper-ratio single-core wire is 0.1-0.5.
In the preparation method of the ultra-low copper ratio superconducting wire with the short production period, the surface of the ultra-low copper ratio single-core wire is subjected to insulation treatment before the cable is twisted.
Furthermore, in the preparation method of the short-production-period ultralow-copper-ratio superconducting wire, the surface is subjected to insulation treatment including painting insulation or electroplating.
In the preparation method of the superconducting wire with the short production period and ultra-low copper ratio, the superconducting cable prepared by the stranded cable is subjected to insulation treatment after the stranded cable is finished.
Further, in the preparation method of the short-production-period ultralow-copper-ratio superconducting wire, the insulation treatment comprises coating of Kapton tapes or braiding insulation.
In another aspect, the present invention relates to a superconducting wire produced by the above-described production method.
Compared with the prior art, the technical scheme provided by the invention has at least the following beneficial effects or advantages:
the invention provides a preparation method of a superconductive wire with short production period, ultralow copper ratio and high current, which uses a stranded cable to replace the processing of a composite wire in the traditional method, and the superconductive wire obtained after the single-core wire is stranded is provided with no additional copper, so that the copper ratio of the superconductive wire is consistent with that of the single-core wire, and the copper ratio of the superconductive wire can be kept low. The preparation method provided by the invention has the advantages of few procedures, simple process, short production period and the like, and can be used for successfully preparing the superconducting wire with short production period, ultralow copper ratio (less than 0.5) and high current so as to overcome the defects of the prior art.
