The typical product is 45# steel, 0.8×1500 mm. The main equipments of the design are the latest ones in cold-strip rolling, which included: shallow-tank hydrochloric acid pickling unit, the entire continuous annealing unit and the entire hydrogen hood-type furnace, skin-pass unit, slitting and shearing line and so on. The designed products included the cold rolled steel sheet, the cold-rolled wide flat steel coil, the cold-rolled ribbon steel coil so on. The design made the products scheme and the metal balance, designed the rolling schedule for the typical product, checked the rolling mills production capacity, calculated the technical and economic indexes. A layout drawing for the designed plant was accomplished. In the special topic of this thesis, The calculation of rolling force computer (C language) application, and discussed with of cold rolled plate surface longitudinal stripe defect causes for the project. 　　　Key words: Cold-rolled strip steel; Process Design; Product design; process; metal balance sheet ；cold rolled plateAlloy 目录 冷轧车间设计 I 摘要 I ABSTRACT II 目录 III 1.综述 1 1.1冷轧综述 1 1.1.1冷轧定义及优势 1 1.1.2冷轧带钢生产的工艺特点 2 1.1.3冷轧带钢主要产品 3 1.1.4 冷轧产品生产的发展 3 1.1.5 冷轧板带生产现状 4 1.2 冷轧板带生产技术 6 1.2.1 酸洗技术 6 1.2.2 轧制技术 6 1.2.3 平整技术 7 1.2.4 带钢涂、镀层技术 8 1. 3 冷轧板带生产的新技术及发展趋势 9 1. 3. 1 冷轧带坯原料的无酸洗除鳞工艺 9 1. 3. 2 液氮冷却机用于带钢冷轧 9 2 产品方案及金属平衡 11 2.1 产品方案 11 2.1.1 编制产品方案的原则 11 2.1.2 产品方案表 11 2.2 金属平衡表 11 3 冷轧主要工艺流程 13 3.1 冷轧板带钢生产的工艺流程 13 3.2 冷轧板带钢各机组生产工艺流程 14 3.2.1酸轧联合机组 14 3.2.2 清洗和退火 15 3.2.3 连续热镀锌 16 3.2.4 涂层机组 1
