a new rolling pressure model for an actual reversing cold rolling strip mill

the forging model for cold rolling is one of rolling models that is used in rolling calculations. in this model,the final rolling pressure is an average value and it is not an accurate model.also by using this model,the firction hill curves are plotted due to the central point of the rolling bite length while frictional stresses intersect at the neutral point.in this study, a new model based on the forging  model is presented to determine the rolling pressure during cold  rolling process for using  in a reversing tandem mill  which is called “improved forging model”. in the new model, the intersection of  frictional forces is the neutral point.finally the computing results from this model coincide well with the investigations done
