Abstract

As a result of the developed method for determination of average resultant of horizontal forces it is possible to specify the mechanism of metal balance maintenance in the rolls. The resultant of applied forces is not directed vertically but inclined aside strip motion at simple stable rolling process. Thus the balance in the deformation zone is maintained due to action of opposite force appearing as a result of "opposite" motion of metal. Hence, retracting forces are spent not only on overcoming pushing forces but also on balancing of applied forces. The arm increases at calculation of the moment of deformation in view of inclination of resultant of contact forces.
