1700清洗机组步进梁结构设计 摘 要 我国冷轧宽带钢得生产始于1960年，首先建立了1700mm单机可逆式冷轧机，70年代投产了我国第一套1700mm连续式无机架冷轧机，到2000年我国已建成8套冷连轧机，6套单机架可逆冷轧机，主要生产碳素冷轧板卷;并建成11套多辊冷轧机，生产电工钢及不锈钢冷轧板卷。步进梁主要应用在冷轧各组的进出料运输和过跨运输。该结构具有行走、升降、等功能，设计结构紧凑，操作稳定，自动化程度高等优点。 关键词：冷轧机， 1700 cleaning crew walking beam structure design Abstract In recent years, the development of cold-rolled strip production technology mainly through the following aspects to enhance the degree of automation, and improved mill structure and production technologies. Including increased coil weight, increase the speed of rolling mill unit and continuously adopt new technology, new equipment, process improvement. Chinas production of cold rolled wide strip was started in 1960, first established 1700mm Single Reversing Cold Rolling Mill, 70 years of our first set put into continuous no rack 1700mm cold rolling mill, by 2000, China has completed eight sets of cold rolling mill, 6 sets of single stand cold rolling mill, the main production of carbon cold-rolled coils; and built 11 sets of multi-roll cold rolling mill, production of electrical steel and stainless steel cold rolled coils Walking beam is mainly used in cold and out of each group had cross-feed transport and transport. The structure of walking, lifting, and other functions, design, compact structure, stable operation automatization Key words ：Cold, hydraulic, bearings are 目 录 1 序言 1 1.1中国钢铁工业的发展概况 1 1.2冷轧带钢生产技术的发展 2 1.3我国冷轧板的发展概况 3 1.4我国冷轧板的生产 3 1.5冷轧工艺过程 4 1.6液压传动与控制 4 1.7上料及运输设备 4 1.8钢卷接受及运送装置 5 2方案的选择 6 2.1选用方案 6 2.2.2入口步进梁设备用途 7 2.2.3入口步进梁原理及结构说明 7 3步进梁的设计 9 3.1主要技术参数 9 3.2活动梁的校核 9 3.2.1活动梁受力概述 9 3.2.2活动梁受力分布图 10 3.2.3活动梁各处剪力、弯矩计算 11 3.2.4活动梁的强度校核计算 12 3.3液压缸工作压力的确定 13 3.4步进梁横移液压缸主要技术参数的确定 14 3.4.1液压缸内径D和活塞杆d的确定 14 3.4.2液压缸流量的计算 15 3.4.3横移液压缸参数的计算 15 3.5步进梁升降液压缸主要技术参数的确定 16 3.5.1升降液压缸液压缸内径D和活塞杆直径d的确定 16 3.5.2升降液压缸流量的计算 18 3.6选择液压缸 18 3.6.1使用工况及安装条件 18 3.6.2步进梁横移液压缸的选择 19 3.7液压泵及电机的选择 19 3.7.1确定液压泵的最大工作压力Pp 19 3.7.2确定液压泵的流量Qp 20 3.7.3选择电机 20
