How to choose a slitting line

1. Start with material thickness and width

The entry section, slitter head, tension unit and recoiler must match the material thickness, width and coil weight. Existing Junjian slitting line references include thickness from 0.2-2.0 mm, project ranges up to 16 mm, entry width references from 600-1250 mm and project ranges up to 2000 mm. Final values should be confirmed with the engineering team.

2. Confirm finished strip width and edge quality

Finished strip width, number of strips and edge quality decide the knife setup and tooling requirement. If the strip is narrow, high strength or surface-sensitive, the line may need closer attention to side guiding, knife clearance and strip handling.

3. Review tensioning and recoiling needs

Slitting quality is not only about the slitter head. Tension control and recoiling stability affect finished coil shape. The line should support stable tension, edge scrap handling and recoiling according to the finished coil weight and downstream use.

4. Match speed with the real production target

Reference slitting line speeds may reach 0-200 m/min, but practical speed depends on material, strip count, coil change time, operator workflow and quality requirements. A balanced line often performs better than a layout selected only for its peak speed.

5. Check workshop layout and service access

Share the available line length, crane position, coil storage direction and maintenance access. The workshop layout can affect the loop pit, recoiling area, scrap handling route and operator stations.

6. Selection checklist

• Incoming coil thickness, width, weight and material grade.
• Finished strip width range and number of strips per coil.
• Edge quality requirement and tooling expectations.
• Target line speed, coil change frequency and production schedule.
• Recoiling quality, tension control and finished coil handling method.
• Workshop drawing, crane capacity and available installation space.
