绪言随着电力工业的发展,电机功率越来越大,锻件重量也在增加,所需提供的原始钢锭更趋向于既大且重。如我国的60万瓩汽轮发电机组,发电机转子锻件重达100吨,钢锭则需210吨左右。国外已经在使用450—500吨钢锭锻制转子。随着原始钢锭吨位的增加,与金属结晶过程中有关的缺陷愈益明显,而水压机吨位却不

INTRODUCTION With the development of the electric power industry, the power of the electric motor is getting larger and the weight of the forging is also increasing. The original ingot to be supplied tends to be both large and heavy. Such as China’s 600,000 瓩 Turbine Generator, generator rotor forging weighing 100 tons, steel ingot is about 210 tons. Foreign countries have been using forged rotor 450-500 tons of steel ingot. As the tonnage of the original ingot increases, the defects associated with the crystallization of the metal become more apparent, whereas the hydraulic tonnage does not
