XW12Z-80x3000 4-Roll Plate Rolling Machine | EZHONG, Hubei, China

EZHONG XW12Z-80x3000 Four-Roll Plate Rolling Machine – Easy, Accurate Rolling for Steel, Stainless and Aluminium

The EZHONG XW12Z-80x3000 is a hydraulic four-roll plate rolling machine for medium-thickness plate, rolling up to 80 mm thick and 3,000 mm wide, and pre-bending plate ends up to 70 mm. The plate is clamped between the two centre rolls throughout the cycle, so it stays square and can't slip, while the side rolls pre-bend both ends and form the shell in one direction without turning the plate. With a 100 kW drive, speeds from 1.5 to 6 m/min and NC or CNC control options, it's a straightforward, single-operator machine for steel, stainless steel and aluminium work.

Why a Four-Roll Machine Is Easier to Use

• The plate is fed once and clamped between the top and bottom rolls
• Both ends are pre-bent by the side rolls without removing or turning the plate
• Constant clamping keeps the plate square and prevents slipping
• The clamping length is around 1.5 times the plate thickness, keeping flat ends short
• Fixed plate position makes the machine ideal for NC and CNC control
• Less operator skill needed than a comparable three-roll machine

How a Rolling Cycle Works

• Set up: The bottom roll and side rolls are positioned for the plate thickness
• Feed and clamp: The plate is fed in level and clamped between the top and bottom rolls
• Pre-bend first end: The rear side roll rises to bend the leading edge
• Pre-bend second end: The plate runs through and the front side roll bends the trailing edge
• Roll: The side rolls are set to the required radius and the plate is rolled into a shell
• Unload: The drop-end opens and the finished cylinder is removed

Applications

• Petroleum and chemical tanks and pressure vessels

Frequently Asked Questions

• What is the maximum plate size? 80 mm thick and 3,000 mm wide, or 70 mm when pre-bending.
• Can it roll stainless steel and aluminium? Yes. It's suited to medium carbon steel, stainless steel and aluminium plate.
• Why choose four rolls instead of three? The plate is clamped throughout, so both ends can be pre-bent without turning it, flat ends are shorter and the machine is easier to run and automate.
• Can it roll cones? Yes. A cone rolling device is included.
• Does it come with CNC? NC control is standard, and a more advanced programmable CNC system is available.
• How much power does it need? The main motor is 100 kW.
• What should I send for a quotation? Plate material and yield strength, thickness and width, minimum rolling diameter, whether you need cone rolling or CNC, and your local voltage and frequency.
