Product Description
High-performance Four Rollers Plate Rolling Machine-W12-30X2000
1. Higher Precision Bending – The 4-roll system ensures better control over curvature, reducing errors and improving roundness.
2. No Pre-Bending Required – Unlike 3-roll machines, a 4-roll design can bend plate edges without needing pre-bending, saving time and labor.
3. Superior Material Handling – Handles thicker plates (up to 30mm) and longer lengths (2000mm) with stability.
4. Reduced Plate Slippage – The additional roll minimizes material movement, ensuring consistent bending.
5. Efficient Operation – Hydraulic or CNC-controlled models allow for faster, automated adjustments and repeatability.
6. Lower Residual Straight Ends – Eliminates flat spots at the ends of rolled plates, improving weld-ready finishes.
7. Wide Application Range – Ideal for steel, stainless steel, aluminum, and other metals in shipbuilding, boilers, and construction.
8. Energy & Cost Efficient – Reduces secondary processing, lowering operational costs.

Key Configurations
Bending Process Step-by-Step
Step 1: Plate Feeding
The metal plate is inserted between the lower rolls and the pinch roll, which grips the leading edge.
Step 2: Initial Pre-Bending (No Need for Separate Pre-Bending!)
Unlike 3-roll machines, the 4-roll design uses the pinch roll to bend the plate's edge in a single pass, eliminating flat spots.
Step 3: Progressive Rolling
The plate advances while the main upper roll presses down, gradually curving it into the desired radius.
The pinch roll adjusts dynamically to maintain consistent curvature.
Step 4: Completion & Unloading
Once the full circle or cone is formed, the rolls reverse to release the finished product.
