由西北工业大学材料科学与工程系和红原锻铸厂、哈尔滨汽轮机厂合作研制的国家“七、五”重大科研攻关项目“大型火电成套设备”的子项目——大型汽轮机末级钛合金长叶片精密锻造技术,经过三年攻关获得成功。所研制的710毫米钛合金长叶片拟在20万瓩汽轮机上挂片运行。西工大、红原锻造厂、哈尔滨汽轮机厂在国内首次推出的大型汽轮机用710毫米钛合金长叶片,是在63吨·米对击锤上实现了整体叶片的精密锻造,采用先进的,特制的全封闭,单边间隙,深止动扣的模具结构装置;在高于常规锻造温度下变形;并增设中间切边工步和
By the Northwest University of Materials Science and Engineering and the Hongyuan Forging Casting Factory, Harbin Turbine Works developed by the state “seven, five” major scientific research project “large-scale thermal power equipment” of a sub-project - the large-scale end turbine titanium long Precision forging blade technology, after three years of research success. The developed 710 mm titanium long blade is intended to be hung on 200,000 瓩 turbine running tablets. The Big Ben and Hongyuan Forging Factory and Harbin Steam Turbine Factory, which are the first ones in China to launch 710mm titanium alloy long blades for the first time, are used for precision forging of whole blades on the hammer of 63 tons · m. The advanced and specially designed Closed, unilateral clearance, deep stop buckle mold structure device; deformation at higher than the conventional forging temperature; and the addition of intermediate trimming steps and
