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 four-high 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. 相似文献
