摘　　要：结合某钢厂高碳钢线材生产线轧制82B钢的工艺参数,在Gleeble1500D热模拟实验机上采用不同精轧温度制度模拟了精轧F1-F4阶段该钢的轧制变形,分析了精轧温度对精轧过程中各道次动态再结晶的影响.研究结果表明,精轧F1-F4道次变形温度的控制对82B线材的组织有重要影响,精轧温度特别是精轧出口温度过高易使F4道次轧制发生不完全动态再结晶,不利于组织控制.Adopting the technique parameters of 82B high carbon steel wire rod steels during finish rolling , the flow behavior of 82B wire rod steels during finish stage F1 -F4 and the effect of the finishing rolling temperature on finishing process of the dynamic reerystal- lization were investigated by using leeblel500D thermal-mechanical simulation tester under different finishing rolling temperature. Ttle results show that control on the finishing F1 -F4 pass deformation temperature has important influence on the microstructure of 82B wirerod; high temperature is easy to make non-fully dynamic recrystaUization occur during F4-pass rolling, which is not conducive to the control of the microstructure of 82B wire rod.
