| Abstract: |
| A threedimensional physical model for Ltype wide extrusion die was established，and the pressure field and velocity field of internal power-law fluid were simulated by ANSYS WORKBENCH and POLYFLOW software. The analysis results showed that，when the die height，damping height and the ratio of start diameter and end diameter of the mainstream channel were 4 mm，3.5 mm，l.2 ：l～l：l，respectively，the extrusion result was good. |
