Abstract: front page image
(EN)The present invention relates to a method for manufacturing magnesium diboride superconductive wire, to the magnesium diboride superconductive wire manufactured using same, and particularly, to a method for manufacturing magnesium diboride superconductive wire by rolling the magnesium diboride raw material powder by using a powder rolling method, wherein the density and connectivity of superconductive powder introduced into a metal coating material can be increased, and accordingly, the actual effective area through which superconductive current can flow may be enlarged. In addition, the manufacturing method of the present invention is advantageous in terms of manufacturing cost and manufacturing speed since the final size of the wire is achieved almost at the onset of processing by employing a powder rolling process. Moreover, the method of the present invention is advantageous in that it can be applied to processes in which various doping materials that function as a flux pinning center are added in order to improve the properties of the flux pinning center of a magnesium diboride superconductive wire under a magnetic field.
(FR)La présente invention concerne un procédé pour la fabrication de fil supraconducteur de diborure de magnésium, le fil supraconducteur de diborure de magnésium fabriqué au moyen de celui-ci, et en particulier, un procédé pour la fabrication de fil supraconducteur de diborure de magnésium comprenant le laminage d'une poudre de matériau brut de diborure de magnésium au moyen d'un procédé de laminage de poudre, la densité et la connectivité de la poudre supraconductrice introduite dans un matériau de revêtement métallique pouvant être améliorées, et la surface utile réelle sur laquelle le courant supraconducteur peut s'écouler pouvant par conséquent être agrandie. En outre, le procédé de fabrication de la présente invention est avantageux en termes de coûts de fabrication et de vitesse de fabrication puisque la taille finale du fil est obtenue presque au début du traitement grâce à l'utilisation d'un procédé de laminage de poudre. En outre, le procédé de la présente invention est avantageux en ce qu'il peut être appliqué à des traitements dans lesquels divers matériaux de dopage qui fonctionnent comme un centre d'ancrage de flux sont ajoutés afin d'améliorer les propriétés du centre d'ancrage de flux d'un fil supraconducteur de diborure de magnésium sous un champ magnétique.
(KO)본 발명은 이붕소마그네슘 초전도 선재의 제조방법 및 이에 의하여 제조되는 이붕소마그네슘 초전도 선재에 관한 것으로 구체적으로는 이붕소마그네슘 원료 분말을 분말압연법으로 압연하는 것을 특징으로 하는 이붕소마그네슘 초전도 선재의 제조방법을 제공함으로써, 금속피복재 내부에 충진되는 초전도 분말의 밀도 및 연결성 향상을 시킬 수 있으며, 이를 통하여 초전도 전류가 흐를 수 있는 실질적인 유효 면적을 크게 하는 효과가 있다. 또한 본 발명의 제조방법은 분말압연공정을 통해 최종 선재의 크기에 가깝게 공정을 시작하여 생산비용과 생산속도 면에서도 유리한 효과가 있으며, 나아가 자기장 하 이붕소마그네슘 초전도 선재의 자속고정 특성 향상을 위해 자속고정점 역할을 하는 다양한 도핑 물질을 첨가하는 공정에서도 본 발명을 적용할 수 있는 장점이 있다.
