Simulation Analysis and Application of Hot Rolled Large Size H-beams
This paper studies a number of large size H-beams with the reference of the actual manufacturing process of H-beams at Laiwu iron & steel Group.The web cracking and cooling waves,as well as temperature field and rolling force,have been tested and analyzed,and the experiments on the performance and microstructure over the full section have been completed.With the help of building H-beams rolling finite element model,thermal mechanical coupled 3D numerical simulation of large size H-beams full rolling process has been realized,furthermore the residual stress transformation during cutting flange,as well as residual stress distribution of hot rolled H-beams,has been accomplished.The method of controlling residual stress has been achieved through numerical simulation.On the basis of the whole rolling process finite element simulations,with the help of the models of austenite evolution,phase transition and microstructure and property prediction,the simulation of 3D microstructure evolution and property prediction has been fulfilled.This paper provides the reference for the numerical simulation and application of hot rolled large size H-beams.
