《新建年产80万吨1790冷轧车间工艺设计毕业设计》.doc

摘 要 由于冷轧薄板具有很高的尺寸精度，表面质量和优良的综合性能，因此得到了越来越广泛的应用，成为国民经济中各生产建设领域所必须的材料，尤其是在家电板和汽车板的应用。它的生产是钢铁工业各工序中的重点、难点，其产量和质量水平反映了一个国家钢铁工业的强弱。本文结合唐钢冷轧薄板厂的相关资料，同时参考了多家现代冷轧厂的资料，设计了年产80万吨1790冷轧车间。设计内容包括选择轧钢机形式、确定布置形式、根据典型品种（厚度为0.5mm）进行压下规程设计和有关计算（力能参数计算、轧辊强度验算和电机能力验算等）。选择辅助设备（包括镀锌、彩涂线等）。主设备采用了酸轧联合机组，退火炉选择连续退火炉，轧机为板形调控灵敏CVC形式和HC轧机。 本设计力图设计出能生产高档家电板和汽车板的冷轧薄板厂，所采用的设备都是经参考相关资料对比后选取的最佳设备，以保证产品的质量和生产的顺利进行，从而实现优质、高产、低消耗、环保的目标。 关键词: 冷轧薄板；酸轧联合机组；冷轧工艺与设备；压下规程 ABSTRACT As cold rolling sheet has high dimensional accuracy, surface quality and excellent overall performance, so it has been more widely used in all areas of production and construction, especially in the household appliances and motor vehicle plates. Its production is the key and difficult to the implementation in the steel industry, and its output and quality reflects a national strength of steel industry. This article combines with the information of Tang steel Cold Mill Plant. At the same time, it refers to other modern cold mill plant. So I design an 1790 Cold Rolling Mill Plant with an annual output of 0.8 million tons. The component of design includes the choice of rolling mill forms, the arrangement of mills, according to the typical varieties (thickness of 0.5mm) to design the reduction of order and calculation (the parameters of force and energy, the strength of roll and the capacity of electrical motor), the choice of auxiliary equipment (including galvanized line, color coating line).The main equipment uses the continuous picking line coupled to tandom mill. The annealing furnace chooses continuous annealing furnace. The mills choose CVC rolls to control the shape of sheet. This article tries to design the Cold Mill Plant capable of producing high-grade household appliances and motor vehicle sheet. Meanwhile, the equipment compared with reference to relevant information and then choose the best equipment to ensure production quality and production proceed smoothly, thus achieving the target of excellent quality , hi
