对 Q690qENH 桥梁钢进行了减量化合金成分设计，降低了 Ni、Cu 元素的质量分数，克服了对 Mo 元素的依赖；基于新一代 TMCP 技术进行短流程工艺设计，生产出屈服强度为745 MPa、抗拉强度为961 MPa、伸长率为16．8％、－40℃夏比冲击功约为166 J 的低成本减量化 Q690qENH 桥梁钢。与传统桥梁钢 TMCP＋淬火＋回火工艺相比，新一代 TMCP 工艺取消了淬火＋回火过程，生产的 Q690qENH 桥梁钢吨钢可节约合金成本约1521．08元，节水约2180 m3／h，节约用电275．37 kW · h；相当于吨钢节约原煤消耗154．20 kg，减少污染物排放量约361．83 kg。对于新一代桥梁钢的生产，在降低物耗能耗、保护环境方面有重要的理论指导意义。
The reduced alloy composition of Q690qENH bridge steel was designed by decreasing the content of Ni and Cu elements and overcoming the dependence on Mo element.The Q690qENH bridge steel with yield strength 745 MPa,tensile strength 961MPa,elongation 16.8% and impact energy 166 J under -40℃ was obtained based on short process design of new generation TMCP technology.Compared with traditional process of TMCP + Quench-ing + Tempering,the new generation TMCP technology cancelled the quenching and tempering process,and the saving alloy cost,water and electricity consumption of per ton steel are about 1 521 yuan,2 180 m3/h ,275.37 kW·h, respectively,equal to saving 154.20 kg coal consumption and reducing 361.83 kg pollutant emissions per ton steel.It will provide important theoretical significance on reducing material and energy consumption and protecting environ-ment for new bridge steels production.
