Simulation and Technology Optimization for Rolling Web Wave of Large Size H-Beam
(0) The rolling process of large size H-Beam NH800×300 in multiple working conditions was simulated by using of commercial finite element method software LS-DYNA.the web wave emerged during rolling of H-Beam was specially demonstrated.The main factor which affected the rolling force during the rolling process has been illustrated.The rolling process under the condition of different horizontal roller radius,different friction coefficient and flange/web stretching ratio were numerically simulated.By means of simulation with different flange/web stretching ratio,it could be concluded that the crucial situation to generate the rolling web wave in typical rolling pass is that the flange/web stretching ratio is about lower than 0.93,which may cause the web unstable and the rolling wave.
