On-Line Implementation of Full Automatic Rolling Control on Plate Mills in Tandem

How to implement the on-line full automatic rolling control on plate mills in tandem was introduced. Comparing the manual control mode with full automatic control mode in plate rolling process, the key points to implement the full automatic rolling control were summarized. Then, the control function was allocated reasonably in a two-level control system. With the coordination provided between the process control system and basic automation system, the full automatic rolling control was therefore implemented successfully in site, including the control of horizontal roller bed, of setting the number of vertical passes and of each and every rolling pass. The implementation indicates that the level of automation is further raised for plate mills.
