Abstract：

To obtain the flow stress of large size angle steel during high temperature deformation, the high temperature uniaxial compression experiment of V-Nb microalloying Q420B angle steel with large size were conducted with the deformation temperature of 750-1100 ℃ and the strain rate of 0.01-30 s-1 on a Gleeble-3500 thermal simulation experiment machine. The results show that under the certain experimental conditions, the high temperature flow stress of the experimental steel increases exponentially with the increasing of deformation temperature, and the high temperature flow stress of the experimental steel increases in a power function with the increasing of strain rate.As the strain amount increases, and the high temperature flow stress of the experimental steel first increases and then gradually reaches stability. Based on the relationship between high temperature flow stress and deformation temperature, strain rate and strain, a high temperature flow stress constitutive equation for V-Nb microalloying experimental steel was constructed. The calculated values have good fitting accuracy with the measured values, which proves that it can be used to calculate the rolling force in the actual production.
