电渣重熔钢30万千瓦电机转子锻件是北京钢铁学院和上海重型机器厂共同合作,于1980年建成了目前世新上最大的200吨电渣炉,经过几年的努力,在完成了我国首台30万千瓦核电站一回路设备所需的一百多个质量要求很高的大锻件后,经对电站锻件的试验研究,掌握大量的试验数据基础上,于1985年投料重熔的一支30万千瓦发电机转子钢锭,经过锻造,热处理粗加工以及有关的检测,全部性能均满足了用户的要求,许多技术指标超过了日本同类锻件的水平。 汽轮发电机转子是汽轮发电机的主要和重要锻件,它要承受高速旋转(3000～3600转/分)所产生的离心力,要承受由自身重量所产生的弯曲应力,并要转送巨大的力矩,要保证绝对可靠。所以既要强度高,又要塑性好、韧性好,还要求材质纯净。国外大锻 Electroslag remelted 300,000 kilowatts of motor rotor forgings is the Beijing Iron and Steel Institute and Shanghai Heavy Machinery Factory co-operation in 1980 built the world’s largest new 200 tons of electroslag furnace, after several years of efforts in the completion of our country The first 300,000 kilowatts nuclear power plant a loop of equipment required for more than 100 high quality forgings, after the test of power plant forgings, master a large number of test data based on the 1985 remelting feed a 300,000 kilowatts of generator rotor steel ingot, after forging, heat treatment roughing and related testing, all the performance to meet the requirements of users, many of the technical indicators over the level of similar Japanese forgings. Turbine rotors are the main and important forgings of turbogenerators. They bear the centrifugal force generated by high-speed rotation (3000 ~ 3600 rpm), bear the bending stress caused by their own weight, and transfer huge Torque, to ensure absolute reliability. So both high strength, but also good plasticity, good toughness, but also requires material purity. Foreign forging
