MODELING AND RESEARCH OF ELECTROMECHANICAL SYSTEMS OF COLD ROLLING MILLS

Abstract

The questions of mathematical description and a complex of computer interconnected models of electromechanical equipment for cold rolling mills taking into account elastic bonds of the first and second kind, the effect of termination, reversing and variability in the thicknesses of the rolled metal strip are considered. A multi-channel diagnostic complex of electric drives of the main mechanisms of cold rolling mills was developed and put into production, which allows real-time monitoring of electromechanical processes, recording in the archive, and also identifying the causes of emergencies. It is proposed the optimization of the control system for interconnected electric drives: the algorithm for controlling the speed of the working stand and the tension of the rolled strip is synthesized, models of these automatic control systems were created. The presented results of researching the synthesized and existing systems are obtained, analyzed and summarized. For scientists, doctoral students, graduate students and undergraduates, as well as project managers and engineers-practitioners of the field of mathematical and computer modeling, automated electric drives and automatic control systems.
