China Slitting Line Factory

The right line gets selected from your material type, coil thickness, coil width, coil weight, target strip width, number of strips, surface requirement, burr requirement, and downstream use.

A line for thin pre-painted coil is different from one for heavy carbon steel. A tube mill strip line may need different attention from a resale slit coil line. We review your coil data and production purpose first.

Large burrs may come from incorrect knife clearance, worn blades, poor blade quality, unstable arbor precision, unsuitable thickness setup, or weak slitter head rigidity.

To reduce them, knife clearance, blade condition, spacer accuracy, material hardness, and head structure get reviewed together. For high burr control, send your material grade, thickness, strip width, and accepted burr level.

Width accuracy depends on knife positioning, spacer precision, arbor alignment, coil guiding, strip tension, and stable recoiling.

If the knife setup is not accurate or the strip moves during production, the final width turns unstable. For width-sensitive applications, the head, spacers, separator, tension system, and recoiler get matched carefully.

Recoiling quality affects coil handling, storage, resale, and downstream production. Poor recoiling causes loose coils, uneven edges, strip overlap, telescoping, surface marks, and feeding problems in the next process.

A good result depends on stable strip tension, proper separator setup, recoiler alignment, suitable pressing force, correct mandrel design, and a suitable unloading method.

Yes, one line can often process different materials within a designed range, but the configuration must match the material types and thickness range from the beginning.

Carbon, galvanized, pre-painted, stainless, and aluminum each have different needs for knife clearance, tension control, surface protection, blade wear, and recoiling pressure. If you plan several materials, send the full range before configuration.

Actual output is not decided only by line speed. It also depends on coil loading, threading, knife setup, strip quantity, recoiling stability, scrap handling, unloading, order changeover, and operator workflow.

For service centers and coil processors with frequent width changes, changeover efficiency can be as important as maximum running speed.

Scratches can come from roller contact, strip guiding, tension pads, separator discs, scrap handling, recoiling pressure, or coil loading and unloading.

For galvanized, pre-painted, stainless, aluminum, and appliance-grade material, the strip path, tension method, roller contact, separator design, and recoiling pressure get reviewed carefully before configuration.

Narrow strips need better control of strip separation, tension balance, separator arrangement, recoiling pressure, and unloading method.

When many narrow strips come from one wide coil, the line must keep each in position before recoiling. If the setup is not suitable, the coils turn loose, uneven, overlapped, or hard to handle.

Slit coil quality directly affects tube mills, roll forming lines, stamping lines, roofing sheet lines, transformer core production, and resale coil business.

If the slit coil has large burrs, unstable width, edge wave, camber, scratches, or poor recoiling, the downstream line faces feeding problems, forming issues, welding instability, extra waste, or production stops.

Send your material type, material grade if available, coil thickness range, coil width range, maximum coil weight, coil ID and OD, target strip width, number of strips, burr requirement, surface requirement, expected line speed, downstream use, and available workshop space.

With this, we review the decoiler, slitter head, tension unit, separator, recoiler, scrap handling, unloading system, control layout, and full configuration more accurately.
