摘要 报告了我国发电设备主力机组600 MW 汽轮机低压转子电渣锭的生产结果。锭重180 t,为世界上最大的电渣锭之一,Δ[C]≤±0.01 % ,[H]= (0.8~2.0)×10- 6 ,[Al]= 0.005 % ~0.007 % ,[O]、[S]= (18~25)×10- 6 。转子锻件约130 t,未发现≥1.6 m m 当量缺陷,芯料冶金质量和性能与转子本体一致。 The production of ESR ingots for LP rotors of 600 MW turbine as principal power sets in China is reported.A 180 t ESR ingot with dia.2.8 m,is one of the heaviest in the world,which composition is:Δ[C]≤±0.01 %,[H]=(0.8 2.0)×10 -6 ,[Al]= 0.005 % 0.007 %, [O],[S]=(18 25)×10 -6 .No≥1.6 mm defect was found in the forgings from the ingot.The test has proved that metallurgical quality and properties of the rotors is homogeneous.
