Definitions

  • a method for the use of a superconducting tape characterised in that prior to the sintering in an oven, the superconducting tape is wound with a radius of curvature dimensioned in such a way that the curvature is adapted to a specific appli- cation, whereafter the sintering is carried out.
  • the invention relates to a method of manufacturing and using a superconducting tape, especially when said tape is to be wound into a coil.
  • the first method involves winding a superconducting tape to a mandrel with or without intermediate insulating layers followed by a sintering in an oven.
  • This method presents high requirements to the mandrel and to the properties of the insulating layers with respect to absorption of heat, and it is suited for the manufacture of coils with a small radius.
  • the second method involves a winding up of the tape with a relatively large radius followed by the tape wound up being sintered in an oven. Not until now the tape is wound onto a mandrel. However, during the winding procedure a risk applies of the superconducting material of the tape brittling due to the small bending radius. The latter applies especially to the manufacture of small coils where the tape is subjected to particularly extensive deformations during the winding procedure.
  • the object of the invention is to provide a method of manufacturing superconducting tapes with small radii of curvature, especially small coils not encumbered with the above draw-backs.
  • a method of the above type is according to the invention characterised in that prior to the sintering in an oven, the superconducting tape is wound up with a radius of curvature dimensioned in such a way that the curvature is adapted to a specific application, whereafter the sintering is carried out.
  • the sintering can be carried out before the tape is wound on a mandrel. In this manner it is possible to manufacture even small coils without the use of special mandrels and insulating layers which can tolerate high temperatures.
  • the superconducting tape may according to the invention be wound up or bent into one or more radii of curvature prior to the sintering, said radii of curvature being dimensioned in such a way that within a predetermined radius of curvature range said radius of curvature is adapted to a specific application, whereby the said radius of curvature range corresponds to the range defining the handling and winding extent of the tape without involving a brittling of the superconducting material.
  • the said radius of curvature range may according to the invention include a radius of curvature being smaller than the final radius of curvature as well as a radius of curvature exceeding said final radius of curvature.
  • the superconducting tape may according to the invention be provided with one or more bending radii, whereby said tape does not brittle when it is placed in the application in question after the sintering.
  • Fig. 1 illustrates a superconducting tape wound into a so-called “pancake shape" for the sintering
  • Fig. 2 illustrates the sintered tape wound on a coil holder
  • Fig. 3 shows the maximum strain in a superconducting tape versus an amendment of the radius of curvature for two different values of the initial radius of curvature.
  • the known "React and Wind” method involves a winding of the tape so as to allow the tape to be placed in an oven for an annealing of the superconducting material. It is, of course, not possible to place several km of tape in an oven without said tape being wound up.
  • a wound up tape is ordinarily called a "pancake-shaped" superconducting tape.
  • Such pancake-shaped tapes are for instance described in EP 0631331 in the name of Sumitomo Electric Industries.
  • Such a wound up tape is encumbered with the draw-back that microcracks can arise in the superconducting material in case said material is bent too much or if said material is subjected to a too extensive deformation. The inventors have tried to map these circumstances, and Fig.
  • this radius of curvature is close to the final radius of curvature, viz. the resulting deformation.
  • the radius of curvature can be slightly smaller or slightly larger than the final radius of curvature. In this manner it is possible to avoid a deformation of the tape to such an extent that microcracks arise during the following placing of said superconducting tape on for instance a mandrel, viz. a coil holder, with intermediate layers of insulating material, i.e. without being subjected to a strain beyond the range of the radius of curvature.
  • the advan- tage is obtained that it is possible to use a mandrel and intermediate insulating material not tolerating the high sintering temperatures of typically 900 °C. In other words a free choice applies with respect to the material used for the mandrel and the insulating layers, which in practice turned out to be a vital factor.
  • the superconducting tape can be wound with a radius of curvature implying that the tape brittles when it is subjected to a strain after the sintering, and according to a particular embodiment the superconducting tape is provided with one or several bending radii, whereby it does not brittle when it is placed in the application after said sintering.
  • the tape is preferably a multi-filament tape because such tapes are more tolerant to bending than the mono-filament tapes.

Abstract

La présente invention concerne un procédé d'utilisation d'une bande supraconductrice, en particulier lorsque la bande est destinée à être enroulée sur une bobine. Selon l'invention, la bande supraconductrice est enroulée avec un rayon de courbure adapté à une application spécifique avant d'être soumise à un frittage dans un four, le frittage étant effectué ultérieurement. L'invention permet d'effectuer le frittage avant d'enrouler la bande sur un mandrin et, par conséquent, de fabriquer même des petites bobines sans devoir utiliser de mandrins spéciaux ni de couches isolantes supportant les hautes températures.
