Roll Cassettes

Tension Leveler Roll Cassettes With 16 mm Work Rolls in GCr15 and 9Cr2Mo

The roll cassette is the core assembly of a tension leveler. Work rolls and intermediate rolls inside it both support and straighten, preventing bending and deflection at high speed so strip thickness stays uniform and the surface stays smooth.

  • 16 mm diameter work rolls
  • Work roll materials GCr15 and 9Cr2Mo
  • Chrome plating around 0.05 mm
  • Hardened layer around 5 mm

Key Benefits

What the cassette controls.

Deflection Prevented At High Speed

Supporting and straightening in one assembly stops the work rolls bending and deflecting during high speed operation.

Uniform Thickness And Smooth Surface

Preventing roll system deflection is what keeps strip thickness uniform and avoids the shape defects that deflection creates.

Material Choice For The Duty

GCr15 and 9Cr2Mo are both available so the roll material matches the load and diameter rather than a single default.

Where It Is Used

Applications.

  • High precision metal straightening lines
  • Cold rolled sheet processing
  • Coating line leveler sections
  • Lines where strip surface quality is specified

Who It Is For

  • Tension leveler operators
  • Maintenance teams replacing cassettes
  • Plants running small diameter work roll cassettes
  • Buyers specifying roll material rather than accepting a default

Problems It Solves

  • Work roll bending at high line speed
  • Thickness variation across the strip
  • Surface defects from roll system deflection
  • Cassette wear reducing straightening accuracy

Technical Features

Cassette specification.

Dual Function Rolls

Work rolls and intermediate rolls inside the cassette perform both supporting and straightening functions.

High Wear Resistant Materials

GCr15 and 9Cr2Mo work roll materials are heat treated for wear resistance in continuous straightening duty.

Chrome Plated Surfaces

Chrome plating around 0.05 mm over a 5 mm hardened layer protects contact surfaces.

Materials

  • GCr15 bearing steel work rolls
  • 9Cr2Mo alloy steel work rolls
  • Chrome plated contact surfaces

Manufacturing Process

Cassette Review

Roll count, diameters and cassette envelope are confirmed from your leveler.

Roll Manufacturing

16 mm work rolls are produced in the selected material and heat treated.

Plating And Grinding

Rolls are chrome plated and finish ground to the cassette tolerance.

Assembly

The cassette is assembled and roll alignment verified.

Quality Control

  • Material certificate for GCr15 or 9Cr2Mo
  • Hardness and hardened layer verification
  • Plating thickness measurement
  • Cassette alignment inspection

Customization Options

  • Work roll material selected per duty
  • Roll count and cassette geometry to your machine
  • Plating specification by strip material
  • Spare cassettes for rotating service

Use Guide

  • Replace 16 mm work rolls as a complete set
  • Check cassette alignment after each rebuild
  • Select 9Cr2Mo where GCr15 wears too quickly
  • Keep one spare cassette for planned shutdowns

How It Compares

Material and configuration choices.

GCr15 work rollsCost effective wear resistance for small and medium diameter cold rolling duty.
9Cr2Mo work rollsHigher strength option where the load exceeds what GCr15 handles comfortably.
Larger diameter work rolls16 mm rolls give tighter bending for thin strip, provided the cassette supports them properly.
FAQ

Tension Leveler Roll Cassettes With 16 mm Work Rolls FAQ

Which work roll material should we choose?

GCr15 suits small and medium diameter cold rolling duty. 9Cr2Mo is used where higher strength is needed. Tell us your strip and load and we recommend one.

Why 16 mm work rolls?

Small diameter rolls give the bending control thin strip needs. The cassette exists to support them so they do not deflect at speed.

What surface treatment is applied?

Chrome plating at around 0.05 mm over a hardened layer of around 5 mm.

Can you build to our existing cassette?

Yes. Send the cassette drawing or a sample with roll count and diameters.

Do you supply replacement rolls separately?

Yes, 16 mm work rolls and the intermediate rolls for the cassette are available as spares.

What do you need to quote?

Cassette drawing, roll count and diameter, line width, strip material and quantity.
