This paper describes the analysis of tension dynamics of steel strip in tandem hot rolling and presents new equations with the effects of interstand strip deflection caused by flexural rigidity, weight and velocity of the strip. The above effects, not considered in existing tension models, are shown to be not negligible. In the analysis, two differential equations, one for tension dynamics and another for strip deflection curve, were first derived based on the theory of the strength of materials. A simple mathematical model for calculating a parameter in tension dynamics was then derived from the differential equation for the deflection curve. The accuracy of the simple model was confirmed to be satisfactory. The obtained equations can be used to increase accuracy in the analysis and simulations of tension behaviors and in online tension control.
