Steel Cut-to-Length Line

The Steel Cut-to-Length (CTL) Line from Shijiazhuang Faith Machinery Co.,Ltd transforms continuous steel strip into accurately sized flat sheets. CTL lines serve a wide range of industries—automotive panel suppliers, appliance manufacturers, and structural panel fabricators—by delivering high throughput and tight dimensional control.

Line Configuration

1. Coil Unwinding and Leveling

• Decoilers with precise brake control feed strip into a horizontal leveler.

• Leveling rolls adjust hydraulically to flatten the strip and remove camber.

2. Pinch-Roll Feeding

• Down-stream of the leveler, pinch rolls grip the strip and advance it toward the shear section.

• Encoder feedback on the pinch rolls tracks strip position to ensure correct cut lengths.

3. Shear Section

• Flying shears synchronized to line speed produce burr-free cuts at speeds up to 120 m/min.

• Guillotine shears handle thicker gauges or slower production rates, delivering square edges and tight tolerances.

4. Sheet Discharge and Stacking

• Stacking arms or robotic palletizers collect finished sheets into organized stacks.

• Adjustable stack heights and automatic strap-wrapping options prepare bundles for shipment.

Precision and Efficiency

• Length Tolerance: The combination of encoder-based feed control and flying shear technology achieves ±0.5 mm cut-length accuracy.

• Edge Quality: Hardened shear blades with automatic gap compensation deliver clean edges without roll-over or deformation.

• Production Flexibility: Recipe management allows rapid switching between sheet sizes, thicknesses from 0.5 mm to 6 mm, and widths up to 2,500 mm.

Automation and Integration

• HMI and Recipe Library: Operators recall line settings for different materials and sheet dimensions in under five minutes.

• Data Logging: Cut counts, downtime events, and maintenance alerts feed into a database for continuous improvement.

• ERP Connectivity: OPC UA interfaces enable real-time reporting of production output and inventory updates.
