Here is the professional English translation of the Slitting Line introduction
Five Core Modules & Technical Innovations
| Module | Technical Highlights | Africa Market Adaptations |
|--------------------|-------------------------------------------------|-------------------------------------|
| Uncoiling System| Hydraulic expansion mandrel + photoelectric centering | Added dust covers (for high-dust environments) |
| Leveling Unit | 9-roll contour leveling (eliminates crossbow) | Reinforced roller hardness (HRC62+) |
| Slitting Head | Disc knives ±0.05mm precision adjustment | Anti-rust coating (coastal corrosion protection) |
| Tension Control Magnetic particle brake + servo rewinding (≤3% tension fluctuation) | Dual-power supply (diesel generator backup) |
| Smart ControlPLC + HMI touchscreen (multi-language support) | Over-temperature auto-shutdown |
Targeted Solutions for Nigerian Pain Points
Unstable power → 380V/220V dual-voltage motors + generator direct-connect interface
Limited skills→Self-diagnostic system (fault codes + WhatsApp remote guidance)
Material variations → Wide-compatibility design (650-1550mm coil width)
Maintenance difficulties → Modular components (knife shaft change <15 min)
Key Performance Parameters
| Specification | Economy Model | Precision Model |
|---------------------|--------------------|---------------------|
| Material Thickness | 0.3-3.0mm | 0.1-6.0mm |
| Slitting Speed | 30m/min | 120m/min |
| Width Tolerance | ±0.15mm | ±0.03mm |
| Min. Strip Width | 10mm | 5mm |
| Power Consumption | 18kWh/ton | 11kWh/ton (VFD energy-saving) |
African Market Investment Value
Typical Applications:
Construction: Galvanized steel slitting → roofing sheet production
Hardware: Stainless steel slitting → door/window fittings
Cost Efficiency (Nigeria Case):
Equipment cost: 35-90 million
Daily capacity: 40 tons (1.0mm GI coil)
ROI Period: 8-14 months (processing fee 8,500/ton)
Selection Guide
1. Material Type:
Carbon steel/galvanized → Choose CRC-coated knives
Silicon steel/copper → Require **ceramic-coated knives
2. Capacity Needs:
20 tons/day → Semi-auto rewinding models
50 tons/day → Full-auto dual-drum models
3. Upgrade Options:
Laser width gauge (real-time edge monitoring)
Scrap winder (reduces manual cleaning)
