The effect of deformation parameters on semi-solid rolling by finite element simulation

For the high melt point iron & steel material, the rigid-viscoplastic analysis modeling of semi-solid materials is made, and the MARC software is used to analyze how the process variables such as gap, rolling speed and initial workpiece temperatures affect stress fields and speed fields. Besides, the rolling experiment for semi-solid material has been done according to the result of finite element analysis. The rolling experiment shows that law of the gap, rolling speed and initial workpiece temperature affect is identical to the calculation results. The speed and temperature controlling are key factors to roll semi-solid slurry successfully.
