Mill Rolls
Forged rolls and mill rolls machined to the pass profile you run
What Mill Rolls Is and Who It Is For
Rolls and mill rolls are forged, heat treated and then machined to the pass profile of the mill they run in. Because the roll barrel, the neck and the drive end all have to be concentric, the part is better made where the forging, the heat treatment and the machining are all scheduled together.
Key Benefits
- Barrel, necks and drive end machined in one accountable supply chain
- Heat treatment condition chosen for the wear and the load
- Pass profile cut to your own groove drawings
- Replacement rolls made from a measured sample when drawings are lost

Who It Is For
- Rolling mill operators
- Section mill maintenance departments
- Equipment OEMs supplying complete roll stands
Problems It Solves
- A roll reground by a third party loses the neck concentricity
- Lost groove drawings make replacement rolls a guessing exercise
- Roll lead times stretch when forging and machining are split
Technical Features
- Forged roll bodies
- Groove and pass profile machining
- Delivery forged, normalised, rough machined, quenched or tempered
- Large component machining capability

- 4140
- 4340
Quality Control
- Concentricity of barrel and necks verified
- Hardness checked across the barrel
- Dimensional report supplied with the roll
Customization Options
- Groove profile to your pass schedule
- Neck and drive end to the existing stand
- Heat treatment condition to suit the product rolled
How We Make It
Roll drawing or sample survey
Open die forging
Quenching
Quenching and tempering as specified
Rough machining
Groove
Groove and profile machining
Concentricity inspection
How It Compares
Forged rolls carry higher toughness than cast rolls for the same hardness, which suits section rolling where shock loading at entry is the usual failure mode.
Use Guide
- Send the groove drawing and the stand dimensions together
- Say which product you roll so the heat treatment condition can be set
- Order a spare set with the first roll to protect the shutdown window
