Abstract: By using elastic-plastic and large deformation FEM, the
contact flattening of the working rolls in cold strip steel rolling is
simulated. And the shape curves after elastic flattening of the working
rolls using numeric method is fitted, then the Hitchcock equation of
calculating the roll flattening radius which can enhance the accuracy of
the control model of rolling force calculating in a wide range is
revised.
Key words: Elastic-plastic Large deformation FEM Contact flattening
