轧制温度及终轧速度对热轧带肋钢筋金相组织和晶粒度影响的探讨

Effect of Rolling Temperature and Finishing Rolling Speed on Metallurgical Structure and Grain Size of HRB

文章介绍了通过工业试验探索开轧温度、上冷床温度以及轧制速度对较大规格φ20～32mm热轧带肋钢筋金相组织和晶粒度的影响,保证了热轧带肋钢筋的金相组织和晶粒度符合生产技术规范。

In this paper, the effects of starting rolling temperature and upper cooling bed temperature and rolling speedon the metallurgical structure and grain size of large size φ20-32mm hot-rolled ribbed bars are investigated through industrialtests, so as to ensure that the metallurgical structure and grain size of the hot-rolled ribbed bars conform to theproduction technical specifications.
