Slitting lines for ferrous and non-ferrous materials

SALICO designs and manufactures fully integrated slitting lines for steel and aluminum coils, covering a complete thickness range from ultra-thin 0.07 mm aluminum to heavy-duty 20 mm carbon steel. Engineered for both high productivity and premium surface quality, these lines are ideal for service centers, coil processing manufacturers, and rolling mills which need to handle demanding materials and tight tolerances.

Advanced slitter head and back tensioning technology

SALICO’s slitting lines feature high-precision, rigid slitter heads with no axial gaps, exceptional concentricity, shafts perfectly parallel, and minimum bending in rotation. These mechanical properties, paired with SALICO’s proprietary hydraulic high-pressure tooling locking, ensure clean cuts, low burrs, and exact slit widths, especially critical in thin aluminum processing.

For tension control, the lines integrate advanced back tensioning devices—such as driven rollers, belt bridle systems, eddy current brakes, and vacuum rolls—to ensure perfect recoiling tension without damaging surface finish or slit edges.

Advantages of SALICO slitting lines 

SALICO slitting lines are designed to maximize productivity while ensuring precision and quality. One of the most notable performance indicators is the line’s ability to operate at speeds up to 800 m/min, enabled by efficient and carefully calibrated back tensioning systems that maintain strip stability throughout the process.

In cases where loop pit depth is restricted due to geological or water table conditions, SALICO offers a double-loop pit configuration. This solution significantly reduces excavation requirements while maintaining line functionality and strip accumulation capacity, providing a practical alternative in space- or depth-constrained installations. 

Automation plays a central role in reducing downtime and enhancing throughput. Robotic solutions developed in-house allow for rapid tooling exchange on both the slitter head and separator shafts, significantly cutting the time required for setup and format changes. These systems are further supported by automatic configuration of the line’s core components, guided by production parameters received directly from the plant’s higher-level IT systems—minimizing manual input and the risk of errors.

The threading phase, often a bottleneck in slitting operations, has been optimized through streamlined strip guidance systems that speed up the transition from coil loading to steady-state operation. To maintain continuous workflow, the line can also include a fast scrapping section at the entry side, allowing operators to discard defective or unwanted portions of the input coil quickly and safely.

After slitting, efficient coil handling and packaging become essential. SALICO lines offer the option to carry out off-line OD banding operations, which can be manual, semi-automatic, or fully automatic depending on the plant’s requirements. This flexibility ensures smooth integration with downstream logistics while maintaining high safety and ergonomic standards for the operators.

A complete solution for slit coil production

With over four decades of experience and in-house manufacturing of key components like slitter heads, scrap choppers, mandrels, and back tensioning devices, SALICO delivers custom slitting lines ready for immediate production. Whether processing soft materials like aluminum or robust carbon steel, SALICO ensures reliability, precision, and maximum line uptime.
