辽宁科技大学本科生毕业设计 年产量155万吨冷轧车间设计 摘要 本设计是参考鞍山钢铁公司1700mm冷轧车间设计的，年产量为155万吨，典型产品为20#冷轧薄板带钢，产品规格0.91400mm。该车间设计主要包括：连续酸洗—冷轧联合机组、罩式退火机组、热镀锌机组、平整机组、剪切机组、重卷机组等。设计产品有冷轧带钢卷、冷轧板、热镀锌板、热镀锌钢卷、电镀锌钢板、电镀锌钢卷。产品具有使用规格范围宽、厚度精确、尺寸偏差小、表面光洁、板形好、性能稳定等特点。据此制定了典型产品金属平衡表和轧制规程，对轧机、电机能力进行了校核。计算了车间的各项经济技术指标，绘制了车间平面图，并以连铸板坯振痕与裂纹的原因与防止为专题进行了综述。 关键词：冷轧带钢；轧制工艺；酸洗—冷轧联合机组；连铸板坯振痕与裂纹 Design of a cold strip plant with annual output of 1.55 million tons ABSTRACT This design refers to the 1700 cold-rolling department of Anshan Steel Corporation, whose annual output is 1.55 million tons, and the typical product is the 20# 0.91400mm. This work shop design mainly includes: continuous scouring and cold-rolled joint unit, cover-type annealling furnace unit, entire continuous annealing unit, hot galvanizes unit, electrical steel annealed coating unit, single stand 4-high skin-pass unit,crosscut and slitting shearing unit, recoiling unit and so on.The designed products,including volumes of cold-rolled strip,cold-rolled plate, hot dip galvanized sheet and volumes,electrical silicon steel plate. Products with distinguishing features such as wide size, accurate thickness, small deviation in dimension,smooth surface, well flateness,stable property,etc.According to it, rolling schedule was made for typical product and the ability to mills and other equipments were checked. And layout drawing for the design plant was completed. A special topic about the flaw and oscillation mark of continuous casting is explicated. Key words: Cold rolled strip; rolling process; continuous scouring and cold-rolled joint unit; flaw and oscillation mark of continuous casting 目录 摘要 I ABSTRACT II 目录 III 1 综述 1 1.1 冷轧生产特点 1 1.2 冷轧产品的发展及应用 3 1.3 冷轧设备 4 1.3.1 PC轧机的概况介绍 4 1.3.2 HC轧机 5 1.3.3 UC 轧机 6 1.3.4 CVC轧机 6 1.3.5 必威体育精装版的UPC轧机 7 1.4 冷轧生产工艺 7 1.4.1 冷轧工艺润滑，冷却，清洗剂 7 1.4.2 酸洗技术 8 1.4.3 轧制 8 1.4.4 精整 9 1.4.5 镀锌 10 1.4.6 矫直 10 1.5 本设计的意义 10 2 产品方案的制定及金属平衡表 11 2.1 产品方案的制定 11 2.2 原料的选择 12 2.2.1 原料要求： 12 2.2.2 热轧带钢卷的技术要求： 12 2.3 金属平衡表的制定 13 2.3.1 金属平衡 13
