摘　　要：对TC4钛合金热连轧过程出现耳子的问题进行了模拟研究,发现孔型设计不合理及轧制速度不匹配是导致热连轧过程中耳子产生的主要原因。通过有限元模拟对孔型及轧制速度进行了优化设计,很好地解决了棒材轧制过程出现的耳子问题,对进一步指导工业生产具有重要的工程意义。In this paper, the hot continuous rolling process of TC4 titanium alloy bars is simulated in terms of FEM, and the ears problem is analyzed. It is found that the unreasonable groove design and mismatch rolling speed is the main reasons for leading to ears. The optimization designs of groove and rolling speed are carried by means of finite element simulation, which avoid the occurring of ears in the process of bar rolling, and have important engineering significance on further guiding the industrial production.
