本文择要介绍核动力装置一回路中全封闭电动闸阀滚动丝杠副的概况,所用材料 1Cr15Co14Mo5VN 钢的生产工艺、主要性能和各种腐蚀试验的结果,以及丝杠副的热态寿命试验和在工程中的使用情况。作者认为,这种新材料的应用虽然解决了滚动丝杆副的脆性断裂问题,而得以取代原用的9Cr18钢,但该材料的耐腐蚀性能仍欠佳,且含钴量较高,价格又昂贵,所以应寻求其他更为合适的材料来取代之。
This article is to introduce the first nuclear power plant a fully enclosed electric gate valve rolling screw pair profile, the material used 1Cr15Co14Mo5VN steel production process, the main performance and corrosion test results, as well as the screw life of hot test and vice The use of the project. The author believes that although the application of this new material to solve the problem of brittle fracture of the rolling screw pair, and to replace the original 9Cr18 steel, but the corrosion resistance of the material is still poor, and high cobalt content, the price Expensive, so should find other more suitable material to replace it.
