EZHONG 260x4200mm Full Hydraulic CNC Three-Roll Plate Rolling Machine – Variable Centre Distance, One-Pass Forming

The EZHONG 260x4200mm is a full hydraulic CNC three-roll plate rolling machine built for very thick, wide plate. It rolls steel plate up to 260 mm thick and 4,200 mm wide, with up to 5,200 tonnes of upper roll force. Its lower rolls move horizontally and independently, so the centre distance can be set for each job: closer together for small-diameter shells, wider apart for maximum thickness. The machine pre-bends plate ends and rolls the full shell in a single feed without turning the plate, making it a strong fit for pressure vessel, wind tower, shipbuilding and pipeline fabrication.

What Makes This Machine Different

• Variable centre distance: Each end of both lower rolls moves independently, so the roll geometry can be matched to the diameter and thickness being rolled
• One-pass forming: Pre-bending and rolling are done in a single feed, with no need to turn the plate over
• Driven upper roll: The upper roll is the drive roll, powered by a four-drive confluence transmission with a stated maximum torque of 4,050,000 Nm
• Shorter straight edges: Anti-slip design, instant motor brakes and fast hydraulic brakes hold the plate in exact position, minimising the flat section left at the plate ends
• Lower foundation cost: EZHONG states foundation costs are around 30% lower than comparable machines

Key Features

• Rolls plate up to 260 mm thick and 4,200 mm wide
• Maximum upper roll pressure of 5,200 tonnes
• CNC control for precise, programmable positioning and bending cycles
• Forms cylinders, cones and arc-shaped sections without auxiliary tooling
• Small-diameter capability by closing the lower roll centre distance
• Motor forward and reverse rotation moves the plate back and forth during rolling
• Solid, high-strength rolls with long service life and low deflection
• Transmission gears in forged high-carbon steel for hardness and wear resistance
• Integral welded steel plate frame for rigidity and stability
• Customisable configurations for specific project requirements

How One-Pass Forming Works

• Feed: The plate is fed into the machine once
• Pre-bend first end: The lower rolls position to bend the leading edge
• Roll: The driven upper roll moves the plate forward and back to form the shell
• Pre-bend second end: The trailing edge is bent without removing or turning the plate
• Result: A rounded shell with minimal straight edge, ready for seam welding

Applications

• Pressure vessels: Thick-walled cylindrical and conical shells
• Wind towers: Large-diameter tower sections with tight curvature control
• Shipbuilding: Heavy hull and structural sections
• Pipelines: Large-diameter pipe shells
• Petrochemical, boiler and heavy structures: Thick plate shells and curved components

Frequently Asked Questions

• What is the maximum plate size? Up to 260 mm thick and 4,200 mm wide.
• What does variable centre distance mean? The lower rolls move horizontally and independently, so the gap between them can be set for each job. A narrower gap suits small diameters, and a wider gap suits thicker plate.
• Do I need to turn the plate to pre-bend both ends? No. Both ends are pre-bended and the shell is rolled in a single feed.
• Can it roll cones? Yes. It can form cylindrical, conical and arc-shaped parts.
• Why is the foundation cheaper? EZHONG states its design reduces foundation costs by around 30% compared with similar machines, and provides detailed installation guidelines.
• Can the machine be customised? Yes. Configurations can be tailored to your production needs.
• What should I send for a quotation? Plate material and yield strength, maximum thickness and width, minimum shell diameter, whether you need cone rolling, and your local voltage and frequency.
