1.高压锅炉主蒸汽管寿命估计: 本文对运行14万小时的主蒸汽管进行了持久强度试验与显微组织的观察。可以看出,使用了14万小时的管子材料组织是稳定的,它的持久强度虽然比使用了5万小时管子材料的强度低了一些,但仍有较高的持久强度与韧性。经电子计算机处理了数据外推表明,它可继续使用5万小时。机械工业部上海材料研究所唐汝钧、鲁惠民、宋传国、强明道、金永祥。2.电站汽轮机叶片断裂失效分析: 影响汽轮机组安全发电的一个重要因素是汽轮机叶片的断裂失效。
1. The estimation of main steam pipe life of high-pressure boiler: In this paper, the long-term strength test and microstructure observation of the main steam pipe running 140,000 hours were carried out. It can be seen that 140,000 hours of tube material is used to stabilize the structure and its long-lasting strength is lower than that of 50,000 hours of tube material, but it still has high durability and toughness. Extrapolation of the data processed by the electronic computer shows that it can continue to use 50,000 hours.
