Abstract:According to the principle of single-roll stirring process, FEM analysis by ANSYS program was adapted to calculate thermal/fluid field under different pouring temperatures, roll velocities and roll-shoe widths during manufacturing A2017 semisolid alloy by single-roll stirring process. The effects of process conditions on thermal/fluid field were analyzed. Process parameters of manufacturing semisolid A2017 alloy were optimized. Proper pouring temperature is 690～790℃, the roll-shoe gap width is 4mm and roll rotating velocity is 0.2m/s.
