A rolling mill preventive maintenance schedule lists the checks and jobs done on the equipment at fixed intervals, how long each takes, and in what order of frequency, so problems are found before the rolling mill fails. This page gives the schedule used in the PlantOps360 task library for rolling mill (and wire drawing machine), which follows common industry practice for general-purpose equipment. It is also searched for as wire drawing, bar mill, rod mill, roughing stand.
The maker’s manual and your site safety procedures always come first where they differ. Intervals set by law differ by state.

| How often | Task | Estimated time |
|---|---|---|
| Daily | Check the roll cooling, lubrication and stand vibration; check the guides and shear | 10 min |
| Daily | Check the gearbox oil pressure and temperature; check the hydraulic system | 5 min |
| Weekly | Check the roll bearings and chocks; check the couplings and spindles | 20 min |
| Monthly | Check the roll surface and gap; check the coiler or reeler and drive | 60 min |
| Quarterly | Check the pinion stand and gearbox and the oil quality; check the main motor | 90 min |
| Half-yearly | Check the screw-down and hydraulic AGC; check the cooling water system | 150 min |

Rolling mill maintenance frequency and yearly workload
At the estimated times, one rolling mill needs about 142 hours of preventive maintenance a year. The biggest single job is “Annual shutdown: overhaul of the stands, gearboxes and couplings; alignment of the mill line” at 600 minutes, done annual. Multiply by the number of units you have to see the workload for your plant.
| Frequency | Tasks | Time per round | Hours per year |
|---|---|---|---|
| Daily | 2 | 15 min | 91.3 h |
| Weekly | 1 | 20 min | 17.3 h |
| Monthly | 1 | 60 min | 12.0 h |
| Quarterly | 1 | 90 min | 6.0 h |
| Half-yearly | 1 | 150 min | 5.0 h |
| Annual | 1 | 600 min | 10.0 h |
What goes wrong on a rolling mill without preventive maintenance
- Roll and bearing wear

- Coupling and spindle wear
What to watch between services
- Roll cooling and lubrication
- Stand vibration and gearbox temperature
- Roll surface condition
Safety and statutory notes for rolling mill maintenance
Hot stock, flying pieces and rotating spindles are hazards. Keep guards and fences in place and lock out before roll changes.
