3. Breakthrough Technology Integration

3.1 Dynamic Width Adjustment System

• Hydraulic Side Guides: Adjust width from 100–450 mm in ≤4.5 minutes.

• Edge Crack Prevention: 40% reduction in stainless/aluminum ultra-thin gauges (0.05 mm).

• No Shim Requirements: Tool-free changeovers vs. 45+ minutes on used cold rolling mill equipment.
  3.2 Thickness Control Revolution

• Gamma-Ray Monitoring: Corrects deviations >0.3% within 0.2 seconds.

• Dual-Mode Processing:

• Ultra-Thin Mode: 0.05–0.3 mm (e.g., medical 316L foil).

• Structural Mode: 0.3–6.0 mm (e.g., Inconel 718 aerospace plates).
  3.3 Siemens S7-1500 PLC Automation

• AI Roll Force Prediction: 90% fewer trial runs vs. manual systems.

• Automatic Crown Compensation: Maintains flatness ≤2 I-units at 30 m/min.

• Real-Time Analytics: 1,000 data points/sec for predictive maintenance.

4. Industry-Specific Applications

◉ Stainless Steel Cold Rolling Excellence

• Medical/Gastronomy: 0.2 mm 316L foil (Ra ≤0.1 µm mirror finish).

• Architectural: 3.0 mm 430 stainless with ≤0.5% thickness deviation.
  ◉ Electronics & Aerospace

• Phosphor bronze shims: 0.1 mm × 450 mm (±0.002 mm tolerance).

• Inconel 718 sheets: 15 m/min rolling under AI-controlled tension.
