| 摘 要： | 在ABAQUS软件的基础上，利用基于稳态判断的数值分析流程，构建了对H型材任意轧制道次进行微观组织演化模拟的分析平台。以某中型H型钢11道次热轧过程为研究对象，详细分析了粗轧过程轧件内奥氏体晶粒直径、温度、动态再结晶区域、动态再结晶奥氏体体积分数，以及道次间隙期间晶粒的长大和温度分布情况。

| Abstract: | An analyzing platform being capable of simulating the microstructure evolution of H-Beam for multi-pass hot rolling was developed based on the route of steady-state judgment.A hot rolling process of typical medial size 11-pass H-beam was simulated with focus on austenite grain size,temperature,regions of dynamic recrystallization,fraction of recrystallizaion,etc.The growth of grain size and temperature distribution for inter-pass period were also simulated. |

| Keywords: | austenite recrystallization steady state judgment medial size H-beam |
