年产90万吨棒材车间设计毕业设计说明书.doc

河北联合大学毕业设计摘要 I 摘要本设计为年产 90 万吨棒材车间工艺设计。品种为圆钢和螺纹钢的小型棒材厂,在此选择Φ 16mm 的圆钢作为典型产品进行该车间的设计。本设计采用全连续轧制生产工艺,全线共有轧机 18 架,其中粗轧机 6架, 中轧机 6架,精轧机 6架,终轧最大轧制速度为 16m/s 。采用主要工艺流程为选定坯料→加热→除鳞→轧制(粗、中、精轧)→冷却(水冷、风冷)→打捆→检查→入库。棒材以定尺交货,横列式、半连续式、全连续式各种轧机都可以进行生产。采用全连续式平立交替布置轧机,以保证产量减少事故。此设计以设计任务书出发,首先论述了棒材的发展概况和市场需求,建厂的必要性和可能性,然后选择典型产品的产品大纲的制定、轧机的选择、孔型系统的选择及典型产品的孔型设计、力能参数的计算及校核、辅助设备的选取、车间布置等。关键词: 车间设计; 孔型设计;棒材河北联合大学毕业设计摘要 II ABSTRACT This is the technology design for producing 900,000 tons ofhot rolled bar workshop per year. Round steel with diameter of16 mm is chosen as typical product of the workshop tobe designed. And we carry out national standard during the production .We use continuous rolling technology , there is18 mill mon ,6 for roughing mill ,6 for medium mill ,6 for finishing mill . The largest end mill speed is about 16 m/s . This paper also analyzed the contemporary rod production in China. A series of problems tobe solved are put forward. The design bases on the design paper, which firstly states the development. The necessity and possibility of setting upa plant are also discussed. Then the design is set out in certain procedures, mainly including the making of product outline, choosing mills, choosing pass system, designing of pass in typical products force and energy parameters calculating and checking, auxiliary equipment, choosing workshop arrangement.
