摘 要本设计说明书是参照鞍钢及宝钢冷轧薄板厂工艺流程，结合现代化生产实际要求设计了年产 150 万吨冷轧薄板钢厂的生产车间。典型产品为 Q235B，20 钢,08Al 冷轧薄板带钢。该车间的主体设备包括：酸洗机组、五机架冷连轧机组、连续退火机组、单机架四辊式平整机组、横切、纵切及卷曲机组等。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。设计时以年产量为基础，结合各产品的市场前景合理地分配了各产品产量，制定了典型产品金属平衡表和轧制规程，并且优化了冷轧薄板的生产工艺，综合了各项技术经济指标，并绘制车间平面图。此外，本说明书还包括专题讨论论文：Mg-4Zn-1.5RE 合金轧制板材的再结晶组织观察与分析。关键词： 冷轧薄板；热处理工艺；再结晶退火；车间设计ABSTRACTThis design manual is a steel work that produces and manufactures 1,500,000 tons cold roll lamella in one year combining modern capacity and physical requirements to design, according to the cold-rolled sheet of Anshan Iron and Steel and Baosteel. The typical products are Q235B, 20 steel and 08Al specifications cold-rolled sheet steel. This workshop equipment includes: pickling line, the five stand cold rolling mill, continuous annealing units, single frame four roller leveling unit, crosscut, longitudinal cutting and rewinding machine, etc. The product can be used in the characteristics of the wide specification range, precise thickness and small size deviation, smooth surface, good board shape, the stable performance and so on. People have assigned each product output reasonably and drew up the metal balanced of the typical model product and stranding system regulations combining each product's market prospect, based on annual output when designing. Not only those, but also people have optimized production process of the cold-rolled sheet, synthesized various technical and economic indicators, and drew the workshop plan. In addition,...
