汽轮发电机转子是发电设备的心脏,质量约几十吨至几百吨的大型锻件需要以1500～3600r/min或更高的速度运转,承受巨大的离心力、传递扭矩和自重产生的弯曲应力,因此要求锻件冶金质量好,材质均匀,晶粒细小,具有高强度、高塑性和高韧性,制造难度大。高规格电站转子锻件的制造依赖冶炼、锻造及热处理全套技术的进步。
Turbine generator rotor is the heart of power generation equipment, the quality of dozens of tons to hundreds of tons of large forgings need to 1500 ~ 3600r / min or more speed, to withstand the huge centrifugal force, the transmission torque and self-weight bending stress , So the forging metallurgy requires good quality, uniform material, small grains, with high strength, high plasticity and high toughness, manufacturing difficulty. The manufacture of rotor forgings for high-specification power stations relies on advances in a full range of technologies for smelting, forging and heat treatment.
