摘　　要：结合汉钢公司HRB600生产实践,通过对比试验数据,重点分析了钢筋化学成分、金相组织、钢材时效三个方面对HRB600强屈比的影响。组织和析出相对HRB600强屈比影响较为明显,提高珠光体含量,钢筋的强屈比得到了显著的提升。Based on the production practice of HRB600 at HanSteel Company,the influence of chemical composition,metallographic structure,and steel aging on the strength to yield ratio of HRB600 was analyzed by comparing experimental data.The influence of microstructure and precipitation on the strength to yield ratio of HRB600 is more significant,and the increase in pearlite content significantly improves the strength to yield ratio of steel bars.

关 键 词：HRB600钢筋 强屈比 微合金化
