EZHONG XW11S-120x3200 Three-Roll Variable Geometry Plate Rolling Machine – One Machine, Many Roll Configurations

The EZHONG XW11S-120x3200 is a hydraulic three-roll plate rolling machine with variable geometry, built to pre-bend and roll medium and heavy plate. It rolls steel up to 120 mm thick and 3,200 mm wide, and pre-bends plate ends up to 110 mm, so shells can be formed in a single feed without turning the plate. Each lower roll moves horizontally on its own hydraulic cylinder, letting the operator set the roll geometry for each job. Close the gap for small diameters, open it for thick plate, or run the machine in a pyramid or asymmetric set-up, so one machine does the work of several.

What Is a Variable Geometry Plate Roll?

• On a traditional three-roll machine, the lower rolls are fixed in position
• On this machine, each lower roll moves horizontally and independently, while the motor-driven upper roll moves vertically
• Changing the roll spacing changes how the machine bends the plate
• Narrow spacing grips the plate better for smaller diameters and thinner material
• Wide spacing reduces the force needed, making thick plate easier to bend
• The plate stays level during pre-bending, which is safer for the operator

Key Features

• CNC control with displacement sensors on upper roll travel
• Three digital readouts show the position of each work roll
• Cone rolling device for conical shells and transition pieces
• Hydraulic drop-end (tilting headstock) for easy unloading of finished cylinders
• Hydraulic balance system and two-speed working system
• Overload protection
• Independent mobile control console
• Welded steel frame with full stress relief
• Rolls forged from high-quality steel, heat treated and induction hardened

Frequently Asked Questions

• What is the maximum plate size? 120 mm thick and 3,200 mm wide, or 110 mm when pre-bending the plate ends.
• What is the advantage of variable geometry? The lower roll spacing can be changed for each job, so one machine handles small-diameter shells and thick plate efficiently, replacing the need for several machines.
• Do I need to turn the plate to pre-bend both ends? No. Both ends are pre-bent and the shell is rolled in a single feed.
• Can it roll cones? Yes. A cone rolling device is included for conical shells and transition pieces.
• How are finished cylinders removed? A hydraulic drop-end tilts the upper roll bearing so the cylinder slides off easily.
• Is it safe to operate? The plate stays level during pre-bending, and the machine has overload protection and a mobile console so the operator can keep a safe distance.
• What should I send for a quotation? Plate material and yield strength, thickness and width, minimum rolling diameter, whether you need cone rolling, and your local voltage and frequency.
