XW12X-60x4200 4-Roll Plate Rolling Machine | EZHONG, Hubei, China

EZHONG XW12X-60x4200 Wide Four-Roll Plate Rolling Machine – 4.2 m Rolling Width for Large Shells

The EZHONG XW12X-60x4200 is a hydraulic four-roll plate rolling machine built for wide plate. With a 4,200 mm rolling width, it forms taller shell sections from a single plate, so large tanks, vessels and ducts need fewer circumferential welds. It rolls steel up to 60 mm thick and pre-bends ends up to 50 mm, with the plate clamped between the centre rolls throughout the cycle so it stays square and never slips. A 100 kW drive, variable speed from 1.5 to 6 m/min and NC or CNC control make it a productive single-operator machine for steel, stainless steel and aluminium.

Why Rolling Width Matters

• Each shell course can be up to 4.2 m tall, compared with around 2.5–3 m on many standard machines
• Fewer courses means fewer circumferential welds, saving welding time, consumables and inspection
• Wide plates can be rolled in one pass instead of being split and joined
• Especially valuable for storage tanks, silos, large vessels and big-diameter ducting

Frequently Asked Questions

• What is the maximum plate size? 4,200 mm wide and 60 mm thick, or 50 mm when pre-bending.
• Why choose a 4.2 m wide machine? Wider plates mean taller shell courses and fewer welds on large tanks and vessels.
• Can it roll stainless steel and aluminium? Yes, as well as carbon steel.
• Do I need to turn the plate to pre-bend both ends? No. The four-roll design pre-bends both ends in a single feed.
• Can it roll cones? Yes. A cone rolling device is included.
• How much power does it need? The main drive 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.
