Abstract
The article describes the algorithm of interaction between rolling stands of a mill of continuous cold rolling through the rolled strip. There is a description of the processed strip as an object of control with elastic and damping properties. Features of interstand tension forming are considered. The influence of rolls position of the adjacent stands on the interstand tension was studied. The authors analyzed the interrelation of speeds of rolls rotation in the adjacent stands taking forward slip into account. The obtained mathematical description made it possible to develop a model to study the properties of considered system. The mathematical modelling was performed in 2011 Matlab package using Simulink application. The results of modelling are compared with real oscillograms of stand no.3 and stand no.4 operating at 2030 PHPP mill of «NLMK». Oscillograms of the mill operation were taken using FADEX program.
