司太立合金用作汽轮机叶片防水蚀材料已得到了广泛应用。近年来国内用锻造、轧制的合金片代替了铸造的合金片,同时,采用高频钎焊或者氩弧焊方法将合金片镶置在叶片上防水蚀的工艺取得了一定经验。于是,如何按着使用要求来选择防蚀片的问题,便成为一个迫切的研究课题。目前,国内关于合金的制造和使用的资料甚少。我们想就目前该合金的生产制造情况结合使用要求,特别是订货中技术条件的确定和验收情况,结合收集到的有关资料进行介绍;同时将该合金采取二次重熔新工艺的技术资料及冷成型报告附后,供有关单位参考。
Stellite alloy used as steam turbine blade water erosion material has been widely used. In recent years, domestic use forged, rolled alloy sheet instead of casting alloy sheet, at the same time, the use of high-frequency brazing or argon arc welding method alloy sheet placed on the blade waterproofing process has gained some experience. Therefore, how to select the anti-corrosion sheet according to the requirements of use has become an urgent research topic. At present, the domestic production and use of alloy little information. We would like to present the alloy manufacturing conditions combined with the use of requirements, especially in the order to determine the technical conditions and acceptance of the situation, combined with the collection of relevant information to introduce; the same time the alloy remelting process to take technical information and Cold-formed report attached for reference by the relevant units.
