15 Roll Heavy Plate Multi Roll Leveler Roll Cassettes
On a heavy plate line the leveler decides flatness accuracy, stress relief and delivery quality, and the roll cassette is the part of the leveler that does the work. This cassette is built for 15 roll heavy plate levelers in a four high quarto configuration, for hot rolled and cold rolled heavy plate.
- 15 roll combined leveling configuration
- Four high quarto roll arrangement
- Quick change function for short shutdowns
- For medium plate and wide heavy plate lines
Key Benefits
What the cassette contributes on a plate line.
Wide Leveling Range
The 15 roll combined arrangement covers a wide leveling range, which is why it is chosen for mixed plate programmes.
High Load Capacity
Combined roll system design carries the load that heavy plate leveling generates without losing roll geometry.
Quick Change In A Shutdown
Quick change functionality means the cassette can be exchanged inside a planned stop rather than a long outage.
Where It Is Used
Lines and products.
- Medium plate production lines
- Wide heavy plate production lines
- Precision leveling of hot rolled heavy plate
- Precision leveling of cold rolled heavy plate
Who It Is For
- Steel producers running heavy plate levelers
- Plate mills chasing flatness and stress relief targets
- Maintenance teams holding a spare cassette
- Project teams upgrading a plate leveling section
Problems It Solves
- Waves and buckles left in heavy plate after rolling
- Residual stress causing distortion after cutting
- Long downtime when the cassette has to be rebuilt in place
- Flatness accuracy falling below delivery specification
Technical Features
Configuration detail.
Four High Quarto Configuration
The cassette uses an optimised 15 roll combined leveling technology in a four high quarto configuration.
Precision Manufacturing
Roll geometry and cassette machining are held to a tight band so leveling results repeat plate after plate.
Combined Roll System
Work, intermediate and support rolls act as one system, which is where the load capacity comes from.
Specifications
Cassette dimensions follow the leveler. Key manufacturing tolerances are listed below.
| Roll Count | 15 roll combined leveler |
|---|---|
| Configuration | Four high quarto type |
| Application | Medium plate and wide heavy plate lines |
| Product Range | Hot rolled and cold rolled heavy plate |
| Manufacturing Tolerance | 0.03-0.05 mm class on critical dimensions |
| Surface Roughness | Around 0.8 micron on working surfaces |
| Change Feature | Quick change cassette |
Materials
- High strength alloy steel cassette frame
- Hardened work and support rolls
- Heavy duty bearing units
Manufacturing Process
Leveler Data Review
Plate thickness, width, yield strength and existing cassette data are reviewed first.
Frame Manufacturing
Cassette frames are machined so roll seat positions hold under heavy plate load.
Roll Production
Work, intermediate and support rolls are produced and ground as a system.
Assembly And Inspection
The cassette is assembled, roll parallelism checked and quick change interfaces verified.
Quality Control
- Critical dimension inspection to the 0.03-0.05 mm class
- Roll hardness and runout records
- Surface roughness verification around 0.8 micron
- Assembled cassette parallelism report
Customization Options
- Roll count and configuration for your leveler
- Cassette interface to your quick change system
- Roll material and hardness for hot or cold rolled plate
- Spare cassette for rotating maintenance
Use Guide
- Keep a second cassette so leveling continues during service
- Check roll parallelism after every rebuild
- Match cassette settings to plate thickness and yield strength
- Inspect support rolls when flatness drifts across the width
How It Compares
Compared with other plate leveling arrangements.
| Levelers with fewer rolls | A 15 roll combined system gives a wider leveling range and better stress relief on heavy plate. |
|---|---|
| Two high leveling arrangement | The four high quarto configuration carries higher load with less roll deflection across wide plate. |
| Rebuilding the cassette in place | Quick change functionality moves the rebuild off line, so the plate line restarts sooner. |

Which levelers does this cassette suit?
15 roll heavy plate multi roll levelers in a four high quarto configuration, on medium plate and wide heavy plate production lines.
Can it handle both hot and cold rolled plate?
Yes, it is used for precision leveling of hot rolled or cold rolled heavy plate to remove waves and buckles.
What tolerances do you hold?
Critical cassette dimensions are held in the 0.03-0.05 mm class with working surface roughness around 0.8 micron.
How long does a cassette change take?
The cassette is designed for quick change. Actual time depends on your crane access and the change frame on the leveler.
Can you build to our existing leveler?
Yes. Send the leveler drawing or cassette dimensions with plate thickness, width and yield strength range.
Do you supply spare rolls for the cassette?
Yes, work, intermediate and support rolls are produced here and can be supplied separately.
