| 摘 要： | 根据某企业以红土镍矿为高炉配矿，因此铁水、钢水中含镍铬元素的特点，提出充分利用镍、铬元素的强化作用开发HRB400E级高强抗震钢筋的研究思路。通过实验室试验，研究了在20MnSi的基体上镍、铬元素的作用规律，优化了钢筋中的镍、铬质量分数。开发的HRB400E级含镍、铬钢筋，镍、铬元素质量分数均为0.2%，力学性能完全满足国家标准的要求，并且无需添加铌（钒）等其他微合金元素。

| Abstract: | There are residual Ni and Cr elements in hot metal and steel， as lateritic nickel ore is used as one of blast furnace raw material. A new kind of HRB400E grade high-strength anti-seismic reinforcement bar is developed by making full use of residual Ni/Cr elements in steel. Based on 20MnSi steel， Ni/Cr effects on rebar’s mechanical properties were studied and Ni/Cr content in rebar is optimized. Both Ni and Cr content are 0.2% in new type HRB400E grade rebar. Without adding other micro-alloying elements， such as Nb or V， rebar’s properties could meet the requirements of China national standard. |
