I. Equipment Overview
This 950mm Rewinding Line is specifically designed for stainless steel (SS) strip rewinding, offering high power, precision control, and robust mechanical construction for medium to heavy-gauge applications.
II. Material & Specification
Material: Stainless Steel (SS)
Thickness Range: 0.1 – 4.5 mm
Width: 920 mm
The machine covers a wide thickness range, suitable for most stainless steel processing scenarios.
III. Drive Motor System (Core Strengths)
| Component | Model | Power | Speed Range | Qty |
|---|---|---|---|---|
| Unwind/Rewind Motor | Z4-355-22 | 315 KW | 300 / 1500 rpm | 2 |
| Straightener Motor | Z4-160-31 | 30 KW | 500 / 3000 rpm | 1 |
| Double S-Roll Motor | Z4-280-21 | 119 KW | 675 / 1600 rpm | 2 |
Dual 315KW main motors: Provide exceptional unwinding and rewinding power for high-speed and heavy-gauge production.
Independent straightener motor: High speed range (up to 3000 rpm) ensures excellent strip flatness before rewinding.
Dual S-roll motors: 119KW each, ensuring stable tension control and high-quality coil formation.
IV. Reducer Configuration
| Section | Model | Gear Ratio |
|---|---|---|
| Unwinding / Rewinding | ZLY450-16-11 | 16 |
| Double S-Roll | ZSY355-22.4-1 | 22.4 |
The well-matched gear ratios balance low-speed torque and high-speed operation, adapting to various thicknesses and speeds.
