Optimal Design of Hot Rolling Strip Mill Housing with Improved GA

Abstract:

Mill housing vibration influents the strip thickness fluctuation. The longitudinal deformation of rolling mill will directly affect plate thickness difference. The longitudinal deformation should be reduced , improving the mill stiffness. Hot rolling mill is seen as is as subject investigated . The improved GA is used to optimize the mill housing parameters. The optimal result is analyzed. The housing stiffness improves. Low order natural frequency improves after optimization, avoiding resonance and improving the housing dynamic stability.
