Advanced mathematical models for predicting sheet profile in hot rolling have been developed. One of the models is a 3-dimensional FEM model, which is named as "CORMILL (Computational Rolling Mill) System", based on the combination of the 3-dimensional rigid-plastic FEM for sheet deformation and the 3-dimensional elastic FEM for work roll deformation. Another is a matrix calculation method which is applicable to sheet profile control in production mills. Numerical analysis of sheet profile and lateral spread is compared with mesurements in 4-Hi experimental hot rolling. As a result, it has become clear that CORMILL System can give us accurate estimation of sheet profile and lateral spread and that the matrix model improved in estimation of rolling force near the sheet edge will have the same accuracy as CORMILL System.
