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091400mm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 155 million tons
ABSTRACT
This design refers to the 1700 cold-rolling department of Anshan Steel Corporation whose annual output is 155 million tons and the typical product is the 20 091400mm 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 unitcrosscut and slitting shearing unit recoiling unit and so onThe designed productsincluding volumes of cold-rolled stripcold-rolled plate hot dip galvanized sheet and volumeselectrical silicon steel plate Products with distinguishing features such as wide size accurate thickness small deviation in dimensionsmooth surface well flatenessstable ording 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 pleted 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
