Abstract：

The forging broadening process of round bar was numerically simulated by Deform-3D software. The veracity of seven empirical formulas from the forging broadening was comparatively analyzed according to the simulation results, and the actual production was validated and compared at the same time. The results of comparative analysis show that both the simulation results and the actual production are basically in agreement with the calculation results; the calculated value of formula 1 is the closest to the minimum diameter of the initial round bar, and formula 1 is the most consistent with actual production; formula 2 has limits and more deviations to some extent; the calculation results of formulas 3，4，5 have more deviations by comparing the simulation results with the actual production; the calculation results of formulas 6,7 have smaller deviations, while the calculation results and the simulation results are in agreement with the actual production when the ratio of width to high is in a small scale.
