During the steel rolling mill production process, when unexpected incidents occur or during normal maintenance shutdowns, specific precautions must be observed after equipment stoppage.
Following an unplanned shutdown, immediately cease feeding steel materials and remove in-process rolling pieces using gas cutting methods to prevent roll stress and potential damage.
For extended shutdown periods:
Activate the lubrication system to maintain proper lubrication of main bearings before final closure to prevent dust ingress
Disconnect power supplies for both the rolling mill and auxiliary equipment
Drain all cooling pipes to prevent freezing and cracking in cold weather
Implement protective measures for lubrication systems, motors, air separators, and slow-drive mechanisms against dust accumulation. Avoid airtight sealing to prevent moisture buildup; instead use small heaters or protective lighting
Place desiccant bags in all control and electrical panels to control humidity, ensuring panels are properly sealed
These maintenance procedures are essential for steel rolling enterprises. Proper shutdown maintenance facilitates smoother production resumption, enhances rolling efficiency, and extends mill service life.
