Abstract A differential equation of tension in tandem rolling was proposed as: dσ_(fi)/dt=E/(h_i integral from n=0 to L (dx)/(h(x)))(v_(i+1)~′-v_i) It seems to be satisfied for those rolling processes of both uniform and variant strip section. The equation may be simplified to one for uniform strip section if it operated through the stands uniformly. Based on the derivation and discussion of the equation an approach to applying the conventional tension differential equation for the computation of the rolling process of variant gage without introducing any error would be incorrect.
