Method & Evidence

AimTo investigate the application of the Finite Element Method (FEM) for simulating and optimizing the hot flat rolling process of aluminum alloys, including predicting rolling loads, torques, temperature changes, and material substructure evolution.
MethodComputational Simulation (Finite Element Method)
ProcedureA 3-D thermomechanical coupled FEM program (FORGE3 V5.3) was used to simulate the hot flat rolling of aluminum alloys. This involved selecting constitutive equations, analyzing a practical pass schedule with measured data, and employing inverse analysis to determine friction and heat transfer coefficients. The study also computed temperature and lateral profile changes, simulated subgrain size and static recrystallization evolution, and developed a new spread formula based on FE analyses. Taguchi experimental design was used to quantify the influence of rolling parameters.
