Development and Application of Control System for Edge-drop of Steel Strips Produced by 1500 mm Five-stand Tandem Cold Mill

Based on the online upgrading project for solving the shifting problem work rolls in Angang 1500 mm tandem cold mill, the function platform for controlling the shifting of work rolls was constructed by making use of the strands from No.1 to No.3 so that the automatic control for edge-drop of steel strips can be achieved with the help of technologies or processes and development of control systems. And the configuration of hardware for the control system for edge-drop and the software design flow were also introduced. The preset calculation method for the process control of the control system for edge-drop was discussed and the compensation algorithm for the basic automatic closed-loop feedback control and the bending compensation of bending rolls were also explained. The production practice shows that the edge-drop of silicon steel sheets can be effectively controlled with the expected results by application of the control system for the edge-drop.
