Preheater tower is the key component of clinker production line, because of its complexity, the installation height is high, the number of multi-component, one-piece heavy weight and become difficult to install one of the largest one child. Preheater tower using a combination of steel and installation, which is the role of steel structures to support the entire preheater system, providing production operations, maintenance operations platform. Entire steel body system of 7 storey, 96.4m (15m-111.4m), member of 9 H-beam, the beam is connected planar layers, upper tread plate, steel structure weighing about 2,500 tons. Preheater in the clinker production mainly from the decomposition of raw material preheating and the role of the entire system respectively, by five cyclone, calciner, tertiary air duct, feed room and other components, equipment installation separately from the feed chamber begins - C1 cyclone ends. Preheater system is also equipped with bucket elevator, feeder, fan, dust collector, elevators and other auxiliary equipments.二 編制依據(jù)Compilation basis1.

Steel structure and the installation of the preheater components mounting height is high, the entire installation area, if using the large mobile crane, the lifting will be not high enough and the less lifting capacity, and the construction speed is very slow. So we will use STT403-24T type crane. Ground preheater group will use a 50-ton crane. Here is STT403-24T crane performance tables and preheater tower crane layout.STT403-24T塔吊吊裝性能表STT403-24T Tower crane performance tableSTT403-24T塔吊載荷信息表STT403-24T Tower crane load chart 塔 吊 布 置 圖 Preheater tower crane layout通過對預熱器塔鋼結構重量的計算，前兩層鋼結構的單件重量達20噸。結合塔吊的吊裝性能標和塔吊的布置圖可以看出：使用STT403-24T塔吊進行預熱器塔的安裝施工滿足不了施工要求，固需要250噸吊車配合吊裝。Through the preheater tower steel structure weight calculation, all steel single piece weighing not more than 12 tons. Combined with crane and crane lifting performance standard layout can be seen: Use STT403-24T preheater tower crane for installation and construction fully meet the construction requirements四Flow Sheet for Guarantee System of Quality and Safety 質量安全保證體系流程圖主管經(jīng)理Mananger：Zhouyougen質量安全：Quantity and safety：BowenshuaiDucumentation：Zhangqing Tech director：Zhu ziwuSupervisor：Xue zhiminXiang xianlunLiftingZhangjieChenlabaoDocumentation record and storageSAFETT SUPERVISOR：YANGHAICHAOthe bridge work execute（50 workers）五.施工工藝過程 The construction processitemtimeactivitymethodtoolsNumber of workersNumber of people aroundFeed-end chamber erectionStart:25/12/13End:10/01/14Size(m)Width:5.15mHeight:8.6mLength:2.55mWeight:16.9ton1.
