Abstract

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.
