从轧钢厂房的设计规范入手,对比了实腹柱、格构柱,排架、刚架体系,简支、连续、桁架式檩条,制动桁架与制动板,屋面梁起拱与不起拱以及不同结构型式的抽柱设计方案、不同的墙架设计方案,定量分析了不同柱距、不同材质、不同结构型式下吊车轨面标高9m、吊车30t的轧钢厂房的耗钢量,提出了多项轧钢厂房轻型化设计的优化方案和经济柱距,供轧钢厂房设计优化使用。 Starting with the design specifications of rolling mill, the contrastive analysis is made on the actual design of the rolling mill, including lattice, column, frame, frame system, simple support, continuous, truss bar, brake truss and brake plate And different types of pumping column design, different design of wall frame, quantitative analysis of the different column spacing, different materials, different structures of the crane rail surface elevation of 9m, crane 30t of the steel plant steel consumption, the proposed multi Rolling Mill Lightweight design optimization program and economic column spacing for the optimization of steel mill design.
