Mathematical models which are necessary to construct the pass schedule of slabbing mills are proposed.The results of this research are summarized as follows;
(1) The equations are introduced by which the rolling force and rolling torque in the horizontal and vertical slabbing mills and the edging mill of hot strip mill are predicted.
(2) The calculation method of the thickness reduction to give the predetermined rolling force or rolling torque without iteration is introduced.
(3) The pass schedule appropriate either for high yield or high production is selectable according to the situation in the present system.
(4) The adaptive calculation method to adjust deformation resistance of rolled material using the ratio of z (=actual rolling force/calculated rolling force) is developed.
These models have been applied to the slabbing mill computer control system of the Kashima Steel Works, Sumitomo Metal Ind., Ltd. and the results are satisfactory.
