设计一个年产24万吨的冷弯型钢、焊管车间，代表产品为钢板桩CSP1-8 摘要 冷弯型钢是一种经济断面型材，具有断面均匀、产品质量高和节能环保的优点，故被广泛应用于汽车、铁路车辆和建筑等行业。根据我国冷弯型钢的技术发展现状和市场的需求状况，本设计车间为年产24万吨的冷弯型钢、焊管车间，代表产品为普通冷弯钢板桩CSP1-8。主要包括设计车间的项目分析、产品生产方案选择、生产工艺流程、设备选型、工艺计算、设备负荷计算、孔型设计、车间平面布置、劳动组织、技术经济指标及环境保护，本文着重论述了代表产品普通钢板桩CSP1-8的孔型设计。 车间内布置一条纵剪生产线和三条冷弯型钢、焊管生产线，其中ZJ1600×12.5纵剪重卷生产线设备负荷率为73.22%，LW500×4生产线设备负荷率为73.7%，LW700×8生产线设备负荷率为73.45%，LW1200×12.5生产线的设备负荷率为76.42%。本设计车间还结合市场数据对各项经济指标进行了核算，计算结果表明本设计车间经济效果显著。 以云南仙福钢铁股份有限公司生产的热轧HRB400级，公称直径为10mm螺纹钢为例，对其进行力能参数计算轧件组织结构分析。 关键词：冷弯型钢；车间设计；冷弯钢板桩；孔型设计 Design of An Annual 240,000 Tons Workshop of Cold-Formed Steel ,Welded Pipe , The Representative Product is CSP1-8,A Kind of Steel Sheet Piling ABSTRACT Cold formed-steel is a kind of economic cross section-profile, with the advantages of uniform cross section,high quality, energy saving and environmental protection,so it is widely used in automobile, railway vehicles and construction industries.According to our country situation of cold-formed steel technology and the demand of the market, the aim of this design workshop is to produce 240,000 tons of cold-formed steel and welded pipe per year,which representative product is CSP1-8, a kind of cold-formed steel sheet piles.Workshop design main contents include project analysis, production plan selection,process equipment selection,process equipment load calculation pass design Workshop layout labor organization technical and economic indicators and environmental protection, this paper discussed the groove design of the representative product in this workshop——steel sheet pile CSP1-8. This workshop features a slitting lines and three cold-formed steel production lines, where slitting equipment load factor is 73.22%,small cold bending production line equipment load factor is 73.76%,the Middle is 73.45%,and the large is for 76.42%. The calculation shows that the economic effect of design workshop is well. Also to production HRB400 of Yun Nan Xianfu Iron Steel Co., Ltd. High Line, nominal diameter 10m
