XW11S-270x3500 3-Roll Plate Rolling Machine | EZHONG, Hubei, China

EZHONG XW11S-270x3500 Three-Roll Plate Rolling Machine – Heavy Plate Bending up to 270 mm

The EZHONG XW11S-270x3500 is a heavy-duty hydraulic three-roll plate rolling machine built to bend very thick steel plate into cylinders, cones and curved sections. It rolls plate up to 270 mm thick and 3,500 mm wide, or 240 mm when pre-bending the plate ends, making it suited to pressure vessels, boilers, ship hulls, pipelines and large structural fabrication. All three rolls are driven, the upper roll position is computer controlled to within ±0.2 mm, and the machine can pre-bend plate ends and roll continuously without leaving flat edges.

What Is a Horizontal Downward Adjustment 3-Roll Machine?

• Three working rolls bend the plate, with the upper roll moving up and down and the lower rolls moving horizontally
• Shifting the lower rolls lets the machine pre-bend the plate ends, so finished cylinders have no flat sections at the seam
• Pre-bending and rolling can be done on one machine without turning or repositioning the plate
• Ideal for thick plate, where flat ends are hard to correct later

Key Features

• Rolls plate up to 270 mm thick and 3,500 mm wide
• Pre-bends plate ends up to 240 mm thick
• End pre-bending and continuous rolling with no flat ends, with the whole process shown digitally
• All three rolls are main driving rolls, each powered by hydraulic motors through planetary reducers
• Planetary drives coupled directly to the roll shafts, cutting power losses and putting more force into bending
• Hydraulic upper roll lifting with computer-controlled positioning and ±0.2 mm synchronisation
• Lower rolls move horizontally by worm gear reducer and screw drive
• Built-in pressure cylinder for rolling cones
• Hydraulic tilting frame and upper roll balance for easy removal of finished cylinders
• Rolls forged from high-quality steel, heat treated and induction hardened
• Friendly HMI with bending process software and automatic compensation during rolling
• Overload protection, safety interlocks and automatic fault alarms
• Fixed control desk plus a remote button box
• Welded steel plate frame for rigidity and stability
• Branded hydraulic and electrical components
• Built to EC safety standards with CE certification
• Can be run by a single operator

Frequently Asked Questions

• What is the maximum plate thickness? 270 mm without pre-bending and 240 mm with pre-bending, on plate up to 3,500 mm wide.
• What does pre-bending mean? The machine bends the leading and trailing edges of the plate first, so the finished cylinder has no flat sections at the seam.
• Can it roll cones? Yes. A built-in pressure cylinder strengthens the machine for conical rolling.
• How accurate is it? The upper roll is computer controlled with ±0.2 mm synchronisation, and the software compensates automatically during bending.
• How many operators does it need? It's designed for single-operator use, with a fixed control desk and a remote button box.
• How big is the machine? Approx. 12,490 × 7,070 × 8,520 mm, so it needs a heavy foundation and a large workshop.
• What should I send for a quotation? Plate material and yield strength, maximum thickness and width, minimum cylinder diameter, whether you need cone rolling, and your local voltage and frequency.
