Abstract :
Control of steel sheet shape and vibration at the air knives can increase the quality, save zinc and reduce costs. In this paper, an electromagnetic actuator set is designed to evaluate the feasibility of using active magnetic levitation technology to control vibration of the steel sheet. Vibration control model is built and incomplete derivative PID controller with series lead compensation is used in this work. Through galvanizing line test, the set can stabilize the sheet motion greatly, improve the galvanizing quality and save zinc.
