Abstract：

The way of extruded aluminum alloy profiles with hollow billets was put forward. The improving extrusion rod meeting the production requirements of hollow billets was designed. The steady simulation analyses of extruded aluminum alloy profiles with hollow billets and solid billets were completed using HyperXtrude FEM software. Extrusion forces, strain field and the distribution of metal flow velocity of the exit of profiles were acquired. The study results indicate that when hollow billets are used to extrude aluminum alloy profiles, the metal flow is more smooth, there is no dead zone in front of the die, metal flow velocity of the exit of profile is more uniform, the SDV is decreased by 87.85% and the extrusion force is decreased by 42.13% compared to that of solid billets. It is correspond with the experiment results.
