Metal Slitting Lines1350S Simple Slitting Line System High-Precision Metal Coil Slitting Machine for Steel & Aluminum Coil Sheet Metal Equipment

I. System Workflow of Simple Slitting Line

This system is designed for high-speed precision slitting of steel coils into strips of specified widths. It consists of four main components: an uncoiler, precision rotary blade holders, a tension station, and a recoiler, supplemented by auxiliary devices, including material handling equipment, pinch rollers, a lead trimmer/scrap chopper, a loop pit, guiding devices, edge trim winders, and discharge units.

Process Overview:

1. Steel coils are loaded onto the uncoiler via a loading car.

2. A hydraulic shear trims the leading edge to remove irregular sections before being fed into the slitter by lateral guides.

3. The material is slit into strips, with edge trim collected by dedicated winders.

4. Strips pass through a loop pit and separator before entering the tension station, which establishes and maintains uniform tension.

5. Strips are wound under consistent tension to prevent loose or collapsed coils.

6. Finished coils are offloaded using a discharge car and transported away.

The uncoiling, slitting, and recoiling processes are automatically synchronized to prevent material stretching, deformation, or misalignment. The tension station regulates overall strip tension, ensuring uniform coil hardness. The system features automatic length cutting, decelerating and stopping at preset lengths or the coil tail end, supporting both automatic and manual scrap chopping. Operations are fully automated except for initial manual threading.
