摘要
结合凌钢工况条件,采用Nb、V复合微合金化开发了HRB500钢筋。基于成分设计和微合金元素溶解度计算,确定了Nb、V含量分别为0.030%和0.010%,连铸矫直温度控制在1100℃以上,钢坯加热温度控制在1050～1150℃的生产工艺。试制结果表明,钢筋性能符合标准要求。
The HRBS00 ribbed bar was developed by Nb-V micro-alloying technology based on the working condition of Lingyuan Iron ＆ Steel Co. , Ltd. The contents of Nb and V was designed at 0. 030% and 0. 010%. The casting strengthening temperature of billet was over 1100℃, and the billet reheating temperature was 1050- 1150℃, The pre-production show that the properties of HRB500 ribbed bar can meet the need of standard.
