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. 年产量120万吨冷轧带钢车间设计:http://www.751com.cn/cailiao/lunwen_31895.html
