第一机械工业部机械制造与工艺科学研究院、上海汽轮机厂、汽轮机锅炉研究所等单位,根据堂八届八中全会指示反右倾、鼓干劲的精神,经过数月的努力,在上海工具厂的帮助下,成功地辊锻出汽轮机叶片,向建国十周年献礼。汽轮机叶片的制造,多年来国内一直采用用方钢铣削的方法,这将浪费大量的合金钢及需要大量的加工机床。近年在模锻、挤压、轧制、拉拔等加工工艺进行了一些试验研究,并取得了一定的成效。但对某些型式的叶片,如方根部等截面的直叶片,及今后应大力发展变断面扭曲叶片,尚不十分适用。叶片辊锻工艺是根据国家的需要,以及它的优越性进行了试验研究的。汽轮机叶片采用辊锻的方法制造,对国民经济来
According to the instructions from the 8th Plenary of the 8th Plenary Session of the 8th Plenary Session of the 8th Central Committee of the Communist Party of China, Machinery and Process Science Research Institute of the First Machinery Industry Ministry, Shanghai Steam Turbine Factory and Steam Turbine Boiler Research Institute, after several months of efforts, With the help of the successful roll forging turbine blades, to the tenth anniversary of the founding of honor. Turbine blade manufacturing, for many years has been the use of square steel milling method, which will waste a lot of alloy steel and the need for a large number of processing machines. In recent years in the forging, extrusion, rolling, drawing and other processing technology conducted some experimental research and achieved some results. But for some types of blades, such as square root section of the straight blade, and the future should be to develop variable cross-sectional distortion of the blade is not yet very applicable. Leaf roll forging process is based on the needs of countries, as well as its superiority of the experimental study. Turbine blade roll forging method of manufacturing, to the national economy
