| 摘 要： | 对预精轧后钒氮微合金化HRB400E抗震钢筋进行淬水试验,研究淬水时间对钢筋表面温度、金相组织、硬度的影响.结果表明,HRB400E抗震钢筋φ20 mm试样在水中的冷却时间应控制在1～3s之间才能保证其良好的入精轧温度范围,在1 010℃保温20 min水冷到室温,在钢筋中会形成少量马氏体、魏氏组织,维氏硬度453 HV.

| Abstract: | The effect of water-quenching time on the surface temperature, microstructure and hardness was researched by means of wa- ter-quenching treatment of vanadium nitride microalloy HRB400E anti-seismic rebars produced after pre-finishing mill. The resuhs show that 20mm rebar has a suitable finishing-temperature range under 1 ～ 3 seconds water-quenching treatment, with small amount of martensite and widmanstatten structures formed in steel matrix while keeping it at 1010 ℃ for 20 minutes , then water-quenching to room temperature, and the hardness is 453 HV. |
