ROLES AND RESPONSIBILITIES DURING UPGRATION :
- RM approach table #3 (6 rolls) & 4 (6 rolls) are having group driven drives. Any problem in shaft or in single roll jamming resulting whole table out of work. These both tables converted in individual driven motors rolls and saved major delay and production lost.
- Laminar cooling is essential to ensure mechanical and metallurgical properties of strip upto mark. Responsible for changing and smooth functioning of main headers (1 to19) post upgradation within time limit.
LOGIC MODIFICATION INITIATED AFTER UPGRADATION :
- Restrict Finishing mill stand screw operation to reduce FM roll change time.
- FM side guide closing logic.
- FM Interstand ON time to reduce FM rolling time.
- Define different laminar cooling strategies to achieve target CT wrt different grades and sections.
