Roller leveler for aluminum sheet and coil processing

Multi Roll Levelers

Roller Leveler for the Aluminum Sheet Processing Industry

A roller leveler applies controlled bending through a precision roll array so ripples, warping and internal stress left by rolling are worked out of the material. On an aluminum line that translates directly into flatness, dimensional stability and fewer rejected sheets.

Key Benefits

What the leveler contributes to an aluminum line.

Flatness And Dimensional Stability

Controlled bending and stress relieving give superior flatness and dimensional stability, so the sheet stays flat after cutting.

Lower Scrap Rate

Eliminating material imperfections before the cut reduces scrap and rework on the finished product.

Throughput Without Compromise

Integrating the leveler in line boosts overall throughput instead of adding an offline correction step.

Where It Is Used

Materials and lines.

Aluminum sheet and coil processing lines
Hot rolled and cold rolled steel levelling
Non ferrous strip finishing
Cut to length lines needing flat feed

Manufacturing Metallurgy and Steel Agriculture Equipment

Who It Is For

Aluminum sheet processors
Service centres handling mixed non ferrous coil
Plants with high scrap rates from shape defects
Project teams adding levelling capacity to a line

Problems It Solves

Ripples and warping after rolling
Internal stress causing distortion after cutting
Coil breaks visible on the finished sheet
Scrap and rework driven by flatness rejections

Technical Features

How the machine works.

Precision Roll Array

The roll array applies controlled bending and stress relieving actions through the thickness of the material.

High Versatility

The same machine handles sheet and coil across hot rolled, cold rolled and non ferrous materials.

Control System For Accuracy

An automated control system holds settings so accuracy and efficiency are repeatable rather than operator dependent.

Manufacturing Process

Material Study

Alloy, thickness, width and incoming flatness determine the roll array.

Frame Manufacturing

Frames are machined so roll positions stay true under bending load.

Roll Production

Leveling rolls are produced, hardened and ground as a set.

Assembly And Test

The machine is assembled and roll gap accuracy verified before shipment.

Quality Control

Frame machining inspection
Roll hardness and geometry verification
Roll gap accuracy measurement
Control system function test

Customization Options

Roll count and diameter for your thickness range
Width to your coil programme
Control interface to your line automation
Entry and exit arrangement for the available space

Use Guide

Set leveling depth from incoming flatness, not from a fixed recipe
Check roll condition when marks appear on soft aluminum
Keep control settings recorded per alloy and gauge
Regrind rolls before surface wear transfers to the sheet

How It Compares

Roller leveling against the alternatives.

Stretch leveling	Continuous in line operation suits coil processing rather than batch stretching.
Manual flattening after cutting	Correcting shape in line removes the offline step and the handling damage that comes with it.
Levelers without stress relief	Controlled bending relieves internal stress so the sheet stays flat after it is cut.
