Study on Head Regional of Hot Forming for Wide-Thick Plate

To analyze the forming rules of the width dimensions reduction change of wide-thick plate head regional, the coupled heat rolling model of was created by the theory of the nonlinear finite element. Under the base of constant wide-thick plate width and different side pressing regulations, the forming rules were obtained for wide-thick plate head width reduction amount and side press amount, rounded analysis of variation of wide-thick plate head width reduction and corresponding experimental research were performed, the calculated results were very inosculated with the measured values, it indicates that the model is reality and credibility. The studied results have provided the theoretical references for controlling wide-thick plate head width reduction during rolling metal.
