摘要/Abstract

摘要： 采用数值模拟和热轧实验研究了轧制速度对2195铝合金热轧(相同轧制规程)过程的影响.结果表明:不同轧制速度板材厚度方向的组织均匀性不同，轧速1.2m/s板材厚度方向的变形组织比0.3m/s板材更均匀；数值模拟获得终轧板材厚度方向的等效应变分布也是轧速1.2m/s板材更均匀，与板材组织特征对应.轧制速度对相同轧制规程终轧板材宽展有影响，1.2m/s终轧板材比0.3m/s终轧板材宽度更大，长度更短，数值模拟与实验结果相对应.数值模拟结果和热轧实验结果在轧制力、温度变化、板材最终形状、厚度方向变形均匀性方面有较好的一致性.

Abstract: The effect of rolling speed on the hot rolling process of 2195 aluminum alloy with the same rolling schedule was studied by numerical simulation and hot rolling experiments. The results showed that the microstructure uniformity along thickness direction is affected by the rolling speeds while the distribution microstructure along thickness direction of plate with the rolling speed of 1.2 m/s is more uniform than that plate with the rolling speed of 0.3 m/s. And the numerical simulation result showed that the equivalent strain distribution along thickness direction of the plate with rolling speed of 1.2 m/s is more uniform than that plate with the rolling speed of 0.3 m/s， which is consistent to the distribution microstructure of the plates. The spreading of rolled plate is affected by the rolling speeds as the rolling schedule is consistent. The spreading of the plate with the rolling speed of 1.2 m/s is bigger than that of plate with the rolling speed of 0.3 m/s. The plate size of the numerical simulation is consistent with the plate size of rolling experiment. The numerical simulation results and the hot rolling experimental results keep in good agreement in rolling force， temperature change， final shape， and uniformity of deformation in the thickness direction.
