摘要
针对大型水轮机转轮用铸造马氏体不锈钢叶片冶炼难度高,曲率大,型线复杂,易变形等特点,通过采用外包玻璃钢的叶片实体模样,严格控制化学成分,制定合理的工艺方案以及利用计算机模拟等措施,成功地生产出质量达到国际先进水平的大型水轮机转轮叶片。
The martensite stainless steel blade castings of the large-scale hydroturbine have some characteristics such as smelting difficulty, large curvature, complex profile line and deforming easily. Adopting blade model with glass fiber reinforced plastic on the surface, controlling the chemical composition strictly, establishing reasonable process scheme and using the computer simulation technology, we produced the large-scale turbine runner blades successfully. The quality of the castings achieves the international advanced level.
