Abstract

Modern cold rolling mills include devices that form a reserve of strip to ensure the continuous operation of the line. Such devices include a horizontal looper containing a direct current drive. The disadvantage of the existing horizontal looper is significant oscillations of the metal strip in the process of its filling, with the maximum amplitude of oscillations occurring when the strip is completely filled. To study the oscillatory processes in the strip, a model of an electromechanical system has been developed. The necessity of taking into account mechanical properties of the steel strip in the development of a model of an electromechanical system has been substantiated. Mathematical and simulation models of a horizontal looper were developed in two extreme positions. The simulation models have been implemented in the MatLab software package. The results of simulation studies showed satisfactory convergence of the experiments with the physical process.
