摘要
综述了近年来汽轮机高、中压和低压转子用材料方面的研究进展。介绍了适用于更高温度和压力的汽轮机高、中压转子用新型高Cr钢材料的开发和优化,指出可通过成分优化和降低杂质含量等途径实现低压转子材料性能的提升,并对相关研究作出了展望。
Recent research development of high-middle pressure rotor and low pressure rotor materials for tur bines is reviewed. The development and optimiztion of the new types of high Cr content steel for high-middle pressure rotors for serving in higher pressure and temperature are introduced. It points out the performance of low pressure ro tor materials is improved by optimizing the composition and reducing the impurity content. The research prospects are forecasted.
