Heavy Duty Coil Leveler for Thick Coil Strip

The BTL series prepares heavy-gauge coil strip for stamping, blanking and cut-to-length lines. Its drive, pinch feeding and roller adjustment are configured for the material load. Choose the machine from the actual width–thickness combination and material strength, then match it to the downstream process.

Why heavy-duty straightening

Thicker Strip Needs the Right Drive, Traction and Roller Setup

A thick coil can fit through the roller opening and still exceed a straightener’s working capacity. Width, thickness and material strength together determine the load on the machine.

BTL combines a suitable drive system, pinch feeding and roller engagement for heavier strip. Its job is to reduce coil set and prepare continuous material for the next operation.

1Check the working load. Compare the actual width at the actual thickness, including the material grade and strength.

2Match the feeding line. Coordinate the decoiler, leveler and feeder with the press, blanking machine or shear.

3Define the output. Required flatness, surface condition and the next process decide whether ordinary coil straightening is sufficient.

For precision stamping, precision coil strip or individual sheets and flat parts with tighter requirements, review the SSL precision leveler and the appropriate configuration.

FAQ

Frequently Asked Questions

What is the BTL coil leveler designed for?

BTL prepares heavy-gauge coil strip for stamping, blanking and shearing by reducing coil set. Select it when the material requires the appropriate heavy-duty drive, traction and leveling capacity. Thickness alone does not determine the required finished flatness.

What materials can the BTL series process?

The listed capacity tables apply to material with yield strength up to 235 N/mm². Mild steel and suitable hot rolled or cold rolled strip are common applications. For stainless steel, high-tensile steel, spring steel, aluminum, copper or galvanized material, provide the grade, condition and strength so the capacity and roller contact can be checked.

How do I choose between BTL-C and BTL-D?

Use the separate capacity tables to check the allowable width at your actual thickness. BTL-C is listed up to 4.5 mm and BTL-D up to 6.0 mm under the stated material conditions. Confirm the minimum working thickness, roller arrangement, drive and control configuration for the final selection.

Can BTL process the maximum width at the maximum thickness?

Not automatically. Each capacity-table cell gives the maximum width at a particular thickness. For example, the BTL-600C table lists 280 mm width at 4.5 mm thickness. Send the width–thickness combinations you actually run and the material grade or yield strength for model selection.

What is the difference between BTL and a precision leveler?

BTL is selected for heavy-gauge coil-set correction before ordinary stamping, blanking or shearing. Precision coil strip, individual sheets and flat parts with tighter flatness or surface requirements should be assessed with a suitable precision leveler such as SSL. Material condition, part geometry and the next manufacturing process also affect the choice.

How are surface-sensitive materials handled?

Roller finish, cleanliness, pressure and material condition all affect the surface. Depending on the specified machine, options can include protective film laminating or suitable roller coverings. For strict cosmetic or precision requirements, review the precision-leveling route and verify the required result with the actual material.

What adjustment and control options are available?

The mechanical configuration uses worm gear screw-jack roller adjustment. Depending on the specified machine, options can include variable-speed control, an openable roller head, servo gap adjustment or recipe recall. Confirm which options are included in the quotation. NC servo feeding controls feed length in the downstream press or shear process.

What information should I send for a quotation?

Send the material grade and condition, yield strength if known, actual width–thickness combinations, coil weight and inner/outer diameters, line speed, required flatness and surface condition, downstream press or shear details, available layout space and destination country.
