Abstract：

In order to optimize the extrusion speed of industrial aluminum profiles with large width to thickness ratio, for a certain hollow industrial 6005A aluminum profile with large width to thickness ratio, and the numerical simulation of steady-state extrusion for different extrusion speeds was conducted by software HyperXtrude. The results show that when the extrusion speed is greater than 2.2 mm·s-1, the inhomogeneities of outlet speed and outlet temperature increase rapidly with the increasing of extrusion speed. When the extrusion speed is greater than 3.4 mm·s-1, the extrusion pressure exceeds the maximum ultimate pressure of extruder. Finally, using the theoretical knowledge of extrusion production to compare and analyze the simulation results, it is determined that the reasonable extrusion speed range of the hollow 6005A aluminum alloy profile with large width to thickness ratio on the extruder of 90 MN is 1.0-2.2 mm·s-1. The optimized extrusion speed is used for the actual production, and the qualified profiles are extruded to prove the reliability of the optimized values of extrusion speed.
