河北联合大学轻工学院 QINGGONG COLLEGE, HEBEI UNITED UNIVERSITY 毕业设计说明书 设计（论文）题目：设计年产200万吨的1700热轧薄板车间 学生姓名： 学 号： 专业班级： 学 部： 材料化工部 指导教师： 2012年5月21日摘 要 本设计为年产200万吨1700热轧带钢车间设计，典型产品厚度为4.0mm。为了满足高质量和高性能板材要求，本次设计结合唐钢1700mm、本钢1700mm、宝钢1580mm、鞍钢1780mm热轧车间设计了年产200万吨的1700mm常规热轧车间。在此设计中详细地介绍了加热、粗轧、热卷取、精轧、冷却、卷取等一系列过程。 本设计采用一架大功率四辊可逆粗轧机，轧制三道次，精轧机选用七架非可逆轧机轧制七道次，通过采用CVC轧机、工作辊弯辊(WRB)和厚度自动控制(AGC)等技术相结合来控制板型和厚度，在精轧前采用无芯轴隔热屏热卷箱。 本设计按照经验制定了典型产品的压下规程，按照要求计算了轧制力，轧制力矩，电机功率等问题，对轧机进行了校核，并且设计了凸度，挠度以及年产量等问题。满足设计要求。 关键词：热轧带钢；压下规程；车间设计；CVC轧机 Abstract This paper design for the workshop is about designing hot-rolling strip steel which produces 2 million tons per year, the typical product thickness is 4.0mm. In order to designing multi-species, the principle of multi-specifications; Based on the above premise, this design combine Tang steel 1700, Ben steel 1700, Bao steel 1580 and An steel 1780 hot rolling production line to design 2 million ton traditional hot continuous rolling workshop. In this paper it is detailly introduced the heat furnace, the rough rolling, the hot curl, the finish rolling, the laminar cooling, the curl and so on. This design uses a high-power four-high reversible rough rolling mill, rolling three times, finishing mill selected seven nonreversible mills rolling seven passes, through the use of CVC mills and WRB mills and the thickness of Automatic Control (AGC) and other technology to control the shape and thickness. In the mill before the adoption of non-core coil box heat shield.  To determine the design of the product in accordance with the requirements of the outline, press a point of order, select all of the major equipment needs, as well as auxiliary equipment. When I Calculated of the rolling force, rolling moment, the electrical power and so on. checking the rolls, designing the crown, deflection and annual output and so on in accordance with the requirements.
