Contact pressure
The roll surface must resist repeated high-load contact without losing the working profile or damaging product finish.
Overview
Rolls that protect product quality and uptime
Rolling mill rolls are working tools, not simple rotating cylinders. Their surface condition affects strip, bar, plate, or section quality, while their geometry, hardness, and bearing interfaces influence vibration, tracking, and maintenance intervals.
- New roll production or replacement based on drawings, samples, and operating requirements
- Reconditioning where worn surfaces, journals, shoulders, or functional diameters can be restored
- Machining, grinding, heat treatment, hard-facing, and inspection support where the roll route requires it
- Assembly and servicing support for roll-related components, bearing interfaces, and return-to-service requirements
- Documentation that links material, process, dimensions, hardness, and final inspection to the exact roll

Operating demands
What rolling lines put into the roll
Thermal cycling
Heat from the rolling process and cooling cycles can affect surface behaviour, cracking risk, and dimensional stability.
Journal alignment
Bearing seats, journals, shoulders, and drive interfaces need controlled geometry so the roll runs correctly in the stand.
Repair decision
When the core remains usable, reconditioning can preserve the base workpiece and focus effort on the worn functional zones.
Production route
From worn roll or drawing to controlled return
Assess
Confirm roll type, damage pattern, operating line, material clues, dimensions, and whether the part is suitable for repair or replacement.
Define route
Select machining, welding, hard-facing, heat treatment, grinding, balancing, or inspection steps around the actual roll function.
Restore geometry
Bring working diameters, journals, shoulders, grooves, and interface areas back to the agreed tolerances and finish.
Assemble and verify
Complete the agreed assembly or servicing scope, then close the job with dimensional checks, hardness readings, NDT where required, and records tied to the finished roll.
Inquiry data
What helps BRUVAL evaluate a roll request
- Roll drawing, sketch, or photos from all sides, including journals and worn working areas
- Roll type, line position, product being rolled, approximate weight, and quantity
- Material grade, current hardness, target hardness, coating or hard-facing requirement if known
- Wear pattern, cracking, pitting, out-of-round condition, journal damage, or surface-finish problem
- Required tolerances, surface finish, inspection standard, and documentation package
- Shutdown window, urgency, and whether the request is for new production, reconditioning, assembly, servicing, or repeat supply
