Research of the Strategy on the Flatness and Gauge Control Based on Coiling Variable Tension Control Process

Abstract:

Based on the analysis and simulation of the variable tension coiling process, integrated control strategy for strip flatness, thickness and tension has been proposed when the last stand adopts the control means of both position closed loop and pressure closed loop. The strategy pre-controls strip flatness and thickness according to the changing tension to decrease accommodation amplitude and enhance product quality. Practical application shows the strategy improves the control precision on the basis of ensuring the stable operation of unit.
