Continuous Casting Roll & Mill Roll Hardfacing Repair
Professional roll rebuilding for steel mills and heavy industry.
JINHUA provides professional hardfacing repair and rebuilding services for continuous casting rolls, mill rolls and industrial rollers.
With long-term experience in wear-resistant and corrosion-resistant hardfacing technology, we combine automated welding equipment, flux-cored hardfacing wire and customized welding procedures to restore worn roll surfaces and extend component service life.
Our solutions are suitable for both preventive hardfacing and repair of severely worn rolls.
What Rolls Can We Repair?
Our hardfacing repair service can be applied to a wide range of large cylindrical wear components.
Roll hardfacing repair service — casting rolls, mill rolls and other large cylindrical components.
Workpiece inspection — wear condition, dimensions and base material.
Roll Hardfacing Repair Process
A typical roll rebuilding process includes six stages, from inspection through to final inspection before delivery.
Workpiece Inspection
Evaluate wear condition, dimensions and base material.
Surface Preparation
Remove damaged or fatigued material where required.
Welding Procedure Selection
Select suitable welding wire, hardfacing alloy and process parameters.
Automatic Hardfacing
Apply wear-resistant overlay using open-arc, submerged-arc or oscillation hardfacing.
Dimensional Restoration
Rebuild the worn surface to the required diameter and profile.
Final Inspection
Check surface condition, dimensions and welding quality before delivery.
Roll rebuilding process — surface preparation, overlay welding and dimensional restoration.
Surface preparation — removal of damaged or fatigued material.
Dimensional restoration & final inspection — rebuilding to the required diameter and profile.
Hardfacing Processes
According to the roll material and application, JINHUA can provide:
The appropriate process is selected according to the required hardness, wear resistance and service conditions.
Open-arc, submerged-arc and oscillation hardfacing — process selected per roll material and application.
Why Repair Instead of Replace?
Hardfacing rebuilding can help customers:
- Extend roll service life
- Restore worn dimensions
- Reduce replacement cost
- Reduce spare-part consumption
- Shorten maintenance cycles
- Improve wear resistance
- Reuse high-value roll bodies
For large industrial rolls, rebuilding is often a more economical solution than complete replacement.
Rebuilding instead of replacing — extend roll service life and reuse high-value roll bodies.
Typical Industries
Our roll hardfacing solutions are widely applicable to:
Steel mills, casting plants and heavy industry — roll repair for abrasive and high-temperature service.
JINHUA Hardfacing Capability
JINHUA provides integrated hardfacing solutions including:
- Automatic hardfacing equipment
- Wear-resistant flux-cored welding wire
- Roll rebuilding and remanufacturing
- Composite wear component production
- Customized welding process development
This allows us to evaluate both the equipment and welding process according to the customer’s actual wear problem.
