摘要/Abstract

摘要： 在Thermecmastor-Z热模拟机上利用双道次压缩方法实验研究30CrMo钢60 mm连铸板坯高温变形道次间隔时间内的静态再结晶行为,分析温度（1000~1150℃）,变形量（0.1~0.22）,变形速率(0.1~10 s^-1)以及道次间隔时间（1~80 s）对其静态再结晶的影响。结果表明,温度、变形量、变形速率及道次间隔时间的增加都会促进30CrMo钢的静态再结晶;30CrMo钢的静态再结晶激活能为184.45 kJ/mol;根据实验数据建立了静态再结晶动力学模型,模型预测结果与实验结果吻合较好。

Abstract: The static recrystallization behavior of steel 30CrMo 60 mm casting slab in interval between double-pass of hot deformation has been tested and studied by Thermecmastor-Z thermal simulator and double-pass compressed method to analysis the effect of temperature (1000 ~ 1150℃),deformation (0.1-0.22) , strain rate ( 0.1-10 s^-1) and inlerval between passes (1-80 s) on static recrystallization. Results show that the static recrystallization of steel 30CrMo is improved with increasing temperature, deformation, strain rate and interval between passes ； the static recrystallization activation energy of steel 30CrMo is 184.45 kJ/mol ； a static recrystallization kinetic model is established based on experimental data and the predicted data better meet the experimental data.
