摘　　要：Q345q桥梁铜减量化试制在未添加其他微合金元素的情况下，通过采用Ⅱ阶段控制轧制和UFC超快冷控制冷却工艺，将钢板的锰含量降至1．1％，试制铜板性能达到国标要求，且有一定富余量，说明采用减量化成分设计生产Q345q桥梁钢是可行的。In the trial-production, The content of Mn was redueted 1.1% and without other low alloys. By exactly ensuring process parameters of eontrolled rolling and controlled cooling by UFC technology, the properties of plates accord with national standard of China, and have superabundance. As is shown the alloy reduce trial rolling production was doable in manufactured Q345q.
