P is the rolling load in tons. a is the lever arm of the resultant total load applied to the the steady-state region of each pass. The roll force and roll torque are the main parame-ters in controlling the atness and geometrical accuracy, yield strength and the hardness of the product, the mill stretch and vibrations of the rolling mill, and roll attening (Lenard, 2002).
