静叶片（导风叶）座为6个弧段拼装而成，其外径达Φ2012 m m，加工后内径为Φ1804 m m，壁厚较薄（最薄厚度仅为20 m m），整个部件重量达到了2.6 T。静叶片装配通过橡胶压缩量进行撑紧，若装配补偿量不足，易导致导风叶松动，影响后续静叶片座的加工。同时，由于静叶片座壁厚较薄，加工易导致变形。文章通过改善静叶片装配与改变静叶片座加工装夹及吊运翻身方式来控制它的变形。
靜葉片（導風葉）座為6箇弧段拼裝而成，其外徑達Φ2012 m m，加工後內徑為Φ1804 m m，壁厚較薄（最薄厚度僅為20 m m），整箇部件重量達到瞭2.6 T。靜葉片裝配通過橡膠壓縮量進行撐緊，若裝配補償量不足，易導緻導風葉鬆動，影響後續靜葉片座的加工。同時，由于靜葉片座壁厚較薄，加工易導緻變形。文章通過改善靜葉片裝配與改變靜葉片座加工裝夾及弔運翻身方式來控製它的變形。

The blower shroud was composed of 6pcs of segment with outside diameter of￠2 012mm and machined inner diameter of￠1 804mm, being a thin wall thickness part (the thinnest thickness was only 20mm) and totaling 2.6T. The blower blade was held tightly depending on the rubber compression in this assembly. In case of that assem-bling compensation was not sufifcient, loosing of the blower blade would occur, thus, influencing the following proce-dure of the machining of the blower shroud. Meanwhile, deformation frequently happened after machining because of the thin wall of the blower shroud. Suggestions were pre-sented in the ifelds of improvement of the blade assembling, clamping way for machining process, machining method and hoisting/turning-over method, to control deformation during process.
