1850 Scale Breaker for Wide Aluminum Strip Production Lines

The 1850 scale breaker is finishing equipment for aluminum strip and sheet. It removes the dense oxide skin from the surface while stretch bend leveling the strip, so the coil reaching cleaning, coating or fabrication is both clean and flat.

  • Maximum working width 1850 mm
  • Typical strip width reference around 1700 mm
  • Removes oxide skin and corrects shape in one pass
  • Line speed reference in the 250-300 m/min band

Key Benefits

Two jobs in one machine.

Oxide Skin Removed

The dense oxide layer adhering to the aluminum surface is broken away, which is what prepares the strip for cleaning and coating.

Shape Defects Corrected

Stretch bend leveling eliminates edge wave, center buckle and crossbow at the same time as descaling.

Built For Wide Format

At 1850 mm maximum working width the machine sits among the core equipment for wide format aluminum strip processing.

Where It Is Used

Lines and products.

  • Aluminum and aluminum alloy coil production lines
  • Surface preparation ahead of cleaning and coating
  • Wide format aluminum strip processing
  • Sheet preparation for automotive components

Who It Is For

  • Aluminum strip producers running wide coil
  • Processors supplying coated aluminum sheet
  • Plants upgrading a descaling and leveling section
  • Project teams building wide aluminum capacity

Problems It Solves

  • Oxide skin interfering with cleaning and coating
  • Edge wave, center buckle and crossbow in wide aluminum coil
  • Separate descaling and leveling steps taking line length
  • Surface quality rejections after coating

Technical Features

Machine characteristics.

Stretch Bend Leveling

Tension combined with bending removes shape defects while breaking the oxide layer.

Wide Format Capability

The 1850 designation refers to maximum working width of 1850 mm for wide aluminum strip.

Finishing Line Integration

The machine is positioned as finishing equipment ahead of cleaning, coating and further fabrication.

Materials

  • Welded and machined machine frame
  • Hardened work and support rolls
  • Tension and bending drive package

Manufacturing Process

Coil Programme Study

Alloy, width, thickness and line speed set the roll configuration and tension range.

Frame Manufacturing

Frames are machined so roll positions stay true under stretch bend load.

Roll Production

Work and support rolls are produced and ground for aluminum surface requirements.

Assembly And Test

The unit is assembled and roll parallelism and drive response verified.

Quality Control

  • Frame machining inspection
  • Roll hardness and finish records
  • Drive and tension system testing
  • Assembly parallelism report

Customization Options

  • Working width to your line
  • Roll configuration for the alloy and gauge range
  • Automation interface to your existing controls
  • Entry and exit layout for the available space

Use Guide

  • Set elongation from incoming shape, aluminum tolerates less than steel
  • Keep roll surfaces clean, aluminum picks up easily
  • Check tension stability when changing alloy
  • Inspect roll condition when surface marks appear after coating

How It Compares

Against separate descaling and leveling.

Chemical cleaning aloneMechanical scale breaking removes the dense oxide skin that cleaning alone struggles with.
Separate leveler downstreamStretch bend leveling happens in the same pass, saving line length and handling.
Narrower machines1850 mm working width covers wide format aluminum strip that narrower equipment cannot process.
FAQ

1850 Scale Breaker for Aluminum Sheet Lines FAQ

What does the 1850 designation mean?

It refers to the maximum working width of 1850 mm, which places the machine among core equipment for wide format aluminum strip processing.

Does it only remove scale?

No. It removes the dense oxide skin and performs stretch bend leveling to eliminate edge wave, center buckle and crossbow in the same pass.

Which materials is it for?

Aluminum and aluminum alloy strip and sheet, in coil production lines.

What comes after this machine?

The strip is prepared for cleaning, coating and further fabrication with a high quality surface.

Can you supply other widths?

Yes. Send your maximum strip width, thickness range and line speed and we configure the machine accordingly.

What do you need to quote?

Alloy, coil width and thickness range, line speed, existing line layout and target surface and flatness requirements.
