Abstract
According to the concept of virtual bending force a rational explanation for SHOHET’s model was presented Considering the deformation characters of the work rolls in fourhigh mill the deformation model of the work roll was regarded as a cantilever beam and new influence coefficients were deduced The effect of the bending force was taken into account independently Therefore the contribution to work roll deflection caused by rolling load rolling pressure between rolls and bending force can be got from the new formulas To validate the accuracy of the formulas the results obtained from the new formulas were compared with those from SHOHET’s formulas It is found that they highly coincide which illustrates that the formulas are reliable
