SIJ Acroni faced significant production bottlenecks at its cold rolling mill due to outdated DC drives and control systems, leading to unsatisfactory productivity and mill unavailability.
ABB upgraded mill drives and automation system, including advanced control loops for roll gap and strip thickness control, enhancing process stability and efficiency. ABB Scope included DCS880 drives for mill stand, coilers & pay-off reel, ABB Ability System 800xA control system including AC800PEC controller with XF801 fast I/O, main control & operator stations, laser speed measurement, motor encoders, interface to existing flatness system, ABB Ability Manufacturing Operations Management for metals.
The modernization resulted in a 15% increase in productivity at the sendzimir mill, improved thickness tolerances, reduced strip breaks, and higher mill availability, meeting both SIJ Acroni's and their buyers' expectations
