The bar mill was started up in 2005, which requires manual interference during rolling. To address this problem, CISDI was contracted to undertake: revamping of DC main drive for Mill #17, 18 (the former DC drive cabinet is replaced) and optimization of former DC main drive system data; modification to rolling line automation program and HMI program; optimization of three flying shear program and drive data to improve the knife positioning, cutting accuracy and yield; replacement of finishing swinging shear equipment to increase the cutting capacity; re-debugging; 

 

As only seven-day shutdown is available for the modernization, it is challenging for CISDI to redevelop the rolling line program and replace the equipment in such limited time, but CISDI engineers have successfully accomplished the task.
