Automatic Control System Design of Two-Roll Cold Rolling Mill Based on Programmable Logic Controller
In order to meet today's demand for precision and efficiency in the rolling process of the two-roll cold mill,and on the basis of the unchanged traditional production process in the rolling steelmaking laboratory of a university,a set of control system is designed for solving the problems such as the low degree of integration of informationization of the rolling process.The system is based on Siemens SIMATIC S7-200 SMART PLC for logic processing,using Modbus protocol to communicate with the frequency converter,and at the same time,relying on the real-time feedback from pressure sensors and displacement sensors,it realizes the precise control of rolling thickness and rolling line speed as well as the automatic adjustment of the rolling process,and then through the Configuration King View real-time production process data visualization.The system is put into use to prove that the development of the control system has improved the efficiency and precision of the rolling process and enhanced the level of informationization integration.
