Abstract
A mathematical model suitable for the determination of mill set-up and investigation of control criteria and mill performance is developed» The model of the reduction of the steel in the roll gaps consists of seven non-linear simultaneous equations while the interstand gap^ descale box and strip waiting to enter mill portions of the model are each described by five non simultaneous equations» The effects of small variations from the operating points of any of the set-up parameters or strip variables are calculated by a linearised set of simultaneous equations using the Jacobian matrices,, Roll bending is included in the model but roll shape deformation due to temperature variation is not included. The most complex portion of the model is the calculation of roll separating force and this equation is obtained by regression analysis on a set of graphical (1) results derived by Cook and McCrum»
