Abstract

La présente invention concerne une enceinte résistante en alliage à base de nickel, comprenant la pièce intégrale de pénétration d'enceinte (9) qui est usinée et fabriquée par la pièce forgée en alliage à base de nickel, et le manchon course (10) de trou borgne approfondi intégral. La pièce intégrale de pénétration d'enceinte (9) est formée par la partie d'enceinte intégrale et la partie de pénétration. Le manchon course de trou borgne approfondi intégral (10) à la structure de trou borgne obturée complètement en haut en bloc. La pièce intégrale de pénétration d'enceinte (9) et le manchon course de trou borgne approfondi intégral (10) sont connectés par le filetage et seront étanches par la soudure en alliage à base de nickel. Les effets bénéfiques de la présente invention sont: d'améliorer la résistance à la température élevée et la résistance à la corrosion, d'améliorer la sécurité de l'ensemble de la enceinte, afin de réduire davantage la difficulté de la maintenance de la centrale nucléaire, de diminuer les coûts de fabrication et de maintenance, de simplifier les travaux du mécanisme des barres de contrôle lors de contrôle en service, tout en réduisant considérablement la difficulté de fabrication d'enceinte et possédant des avantages économiques.The present invention relates to a strong nickel-based alloy housing, comprising the integral enclosure penetration part (9) which is machined and fabricated by the nickel-based alloy forging, and the race sleeve (10) of Integral deep blind hole. The integral enclosure penetration part (9) is formed by the integral enclosure part and the penetration part. Integral deep blind hole race sleeve (10) to the blind hole structure completely closed at the top in block. The integral enclosure penetration part (9) and the integral deep blind hole race sleeve (10) are connected by the thread and will be sealed by the nickel-based alloy weld. The beneficial effects of the present invention are: to improve the high temperature resistance and the corrosion resistance, to improve the safety of the entire enclosure, in order to further reduce the difficulty of maintenance of the plant nuclear, reduce manufacturing and maintenance costs, simplify the work of the control bar mechanism during in-service control, while significantly reducing the difficulty of manufacturing speaker and having economic benefits.
