RESEARCH ON DIGITAL SIMULATION OF VIRTUAL ROLLING MILLS FOR CONTINUOUS COLD STRIP ROLLING PROCESS

摘要

Based on the analysis of the practical production process of continuous cold strip rolling mills, the composition structure of virtual rolling mills is defined in this paper, and a synthetic model for the virtual rolling mills is established consequently. In accordance with the mechanism model, the virtual rolling mills system is divided into three subsystems: screw-down system, speed control system as well as tension control system. The established mechanism model involves the modeling of mechanism, electric system, fluid power and control system, measuring instruments and etc. The results of both simulation and experiment prove that the developed system of virtual steel rolling mills is valid.
