Process simulation of the strip reeling on the cold rolling mill coiler

The paper analyses the dynamic properties of a complex multi-motor electromechanical “cage - strip - coiler” system for a cold rolling mill, the technological modes of which feature significant speed changes during the rolling. Indirect belt tension control systems applied to boost the adjustment accuracy by reeling up the coiler should provide the compensation nodes of the dynamic current drive. Mechanical losses changing at non-linear velocity dependence affect on the mill regulation accuracy. This also demands for the additional loss compensation unit. Strip tension adjustment accuracy depends on those units installation. The system has a complex multi-motor structure. The forenamed conditions require conducting analysis with modeling methods. This paper presents a model of a complex multi-motor system, which provides for the research and installation of the regulation system units in different modes.
