A three-dimensional numerical model is developed here to predict the edge wave behavior of hot rolled steel during run out table cooling based on a finite element (FE) method. The edge wave of the hot rolled steel is reproduced successfully using the FE simulation considering proper thermo-mechanical boundary conditions. The simulation results demonstrate that the edge wave could be caused by the strain gradient due to the temperature difference between the edge and center regions. The maximum amplitude of the edge wave is used as a parameter of the degree of edge wave for quantitative comparison. The effect of the edge mask width and the checkers on the edge wave is examined through a series of process simulations. The measured temperatures agree fairly well with the predicted data.
