摘要冷軋帶鋼具有表面質量高、性能好和用途廣等特點。特別是隨著汽車產業和消費電子行業的迅速發展,人們對汽車及家電外殼的質量和性能要求也越來越高,因此冷軋帶鋼的發展是必要的。設計闡述了冷軋帶鋼的生產工藝特點、應用、發展狀況并簡要介紹冷軋薄板帶鋼的生產工藝流程,進而設計出冷軋產品、特深沖產品、熱鍍鋅產品、電鍍鋅產品和涂層產品。在本設計中,本人研究了先進的技術和設備,并討論了在國內外的技術和配套設備與軋機,尤其是參考的參數和數據都是以寶鋼冷軋薄板廠生產線為基準的,這樣可以達到這樣的設計車間工藝合理,設備先進的目的。本次設計典型產品為ST14,設計的題目是年產120萬噸的冷軋帶鋼車間。冷軋車間有很多,比如寶鋼的2030冷軋車間以及1580車間等等。生產流程初步確定為與寶鋼2030冷軋車間相似。本次設計的流程是:熱軋板卷料 連續酸洗機組 五機架四輥冷連軋機 連續退火機組 單機架四輥平整機組 橫剪 縱剪 檢查,重卷 成品。主要設備有連續酸洗生產線,五機架冷連軋機,單機架四輥平整機組,橫切,縱切等機組。本次設計的特點是:帶鋼成品厚度為0.35mm,產品為深沖鋼板,成品交貨狀態為軟態,在軋制結束后需要對其進行熱處理,已達到所求效果。針對典型產品ST14,按照車間設計的步驟,主要完成了產品大綱的制定、主輔設備的選擇、金屬平衡表的計算、壓下制度分配、軋制規程的計算、軋制圖表的計算、軋制力的計算、軋輥強度的校核、電機能力校核和車間平面布置等。最后,對設計的車間的勞動定員、環保技術、經濟技術等進行了初步設計。設計力求設計生產汽車板冷軋薄板廠,因此該設備使用的相關信息,通過參照比較后選擇了最好的設備,以保證產品質量和生產的順利進行,以實現高品質,高產,低耗,環保的目標。設計的最后附車間設計平面CAD圖。34408 源¥自%六:維;論-文'網=www.aftnzs.live

Abstract
Cold-rolled strip has many characteristics,such as high surface quality,better performance,more varieties and so on. In particular,as the development of automobile industry and home appliances industry,it has been demanded higher quality and performance in the shell of cars and home appliances. Therefore,it is very necessary to develop the cold-rolled strip. The design described processing features, application, development of the cold-rolled strip steel, and briefly introduced production technology, designed cold-rolled products, super deep punched products, hot galvanized products, electrogalvanized products, and coated products. Refer to the design of domestic and foreign advanced technology of the rolling mill,rolling mill equipment,technology and some discussion of auxiliary equipment,especially reference to the Baosteel and Steel cold-rolled sheet production line parameters,making the design process to achieve a reasonable workshop,advanced equipment. Its typical product is ST14,the purpose is to design an annual output of 1.2 million tons of cold rolled strip steel plant. There are a lot of cold rolling plant,for example,baosteel 2030 cold rolling workshop and baosteel 1580 cold rolling workshop,ect. Preliminary determine the production process is similar to baosteel 2030 cold rolling workshop.The design of the process is: Hot-rolled coil pickle line processor five-stand tandem cold roller continuous annealing line single stand four roller leveling unit cross shear longitudinal shear check and rewinding end product. Its main equipments include shallow-tank picking train,5-stand- fully-continuous cold rolling train,single stand 4-high skin-pass train,6-zone pull-through type continuous annealing line,cross-cutting,ect. The design features are: the thickness of the strip is 0.35mm,the product is deeo red sheet ,delivery is soft. After the rolling ,the heat treament is carried out and the effect is reached.  Accoring to typical product ST14,steps in accordance with the workshop design,I mainly complete the product outline of the development,main and auxiliary equipment options,calculation of metal sheets,press distribution,the calculation of order rolling,rolling chart, the calculation of rolling force and roll strength,motor ability checking and workshop layout,ect. This article tries to design the Cold Mill Plant capable of producing motor vehicle sheet. Meanwhile,the equipment compared with reference to relevant information and then choose the best equipment to ensure production quality and production proceed smoothly,thus achieving the target of excellent quality,high productivity,low cost and environment protection. Finally, the design of the plane attached workshop design CAD drawings. 年產量120萬噸冷軋帶鋼車間設計:http://www.aftnzs.live/cailiao/20190408/31895.html
