WyRoll 3R Series 3-Roll Plate Rolling Machine

The WyRoll 3R Series is a 3-roll plate rolling machine with heat-treated 42CrMo alloy-steel shafts, a variable-flow hydraulic system and 3–5 axis CNC control, available in 5 configurations — from the 3R 1224 (12 mm thickness, 2400 mm width) to the 3R 20-4060 (20 mm thickness, 4060 mm width) — designed for manufacturers of tanks, pressure vessels, heat exchangers and industrial cylindrical structures that require a rolling accuracy of up to ±0,08 mm and a capacity of 30 tonnes maximum plate weight. Compared with the 2-roll system of the WyRoll 2R series, this 3-roll plate rolling machine offers greater capacity at the same installed power and a smaller minimum rolling diameter (200 mm on the 3R 1224 model).

The 3-roll system of the WyRoll 3R Series 3-roll plate rolling machine uses the classic configuration with a top roll and two bottom rolls (or variants with asymmetric geometry), with heat-treated and ground 42CrMo shafts for maximum durability on abrasive materials, and a variable-flow Yuken/Daikin Japan + Bosch Rexroth hydraulic system for smooth and precise control of the pressure throughout the rolling cycle.

Key advantages of the WyRoll 3R Series 3-roll plate rolling machine

• 42CrMo alloy-steel roll shafts — maximum durability on abrasive materials — the WyRoll 3R Series 3-roll plate rolling machine uses heat-treated and precision-ground 42CrMo alloy-steel shafts, compatible with carbon steel, stainless steel and special alloys, with a significantly longer service life than standard carbon-steel shafts on materials with a high silicon or manganese content.

• Rolling accuracy up to ±0,08 mm — superior to the 2R series — the 3R 04-2048 and 3R 04-2560 models of the 3-roll plate rolling machine reach a rolling accuracy of ±0,08 mm — 37,5% more precise than the ±0,5 mm accuracy of the 2R series — suitable for applications that require tight shell-roundness tolerances.

• Variable-flow Yuken/Daikin + Bosch Rexroth hydraulic system — the variable-flow hydraulic pump ensures the smooth and precise stepless adjustment of the rolling pressure, with servo functions and continuous parameter monitoring, consuming energy proportional to the actual load compared with fixed-flow pumps that operate permanently at maximum flow.

• CNC control with 3–5 axes and 30 stored rolling programs — the advanced CNC system of the 3-roll plate rolling machine stores 30 rolling programs with all parameters, with a touchscreen, automatic diagnostics and software updates; switching between programs is done in a few seconds without manual re-entry of data.

• Automatic feeding and centering system — accuracy ±0,5 mm — the automatic feeding and centering system with a HIWIN press and pneumatic cylinders centers the plate with ±0,5 mm accuracy before it enters the rolling zone, ensuring that the axis of the produced shell coincides with the programmed axis and eliminating the alignment errors caused by manual positioning.

• CNC lateral support system with deflection compensation — the CNC lateral support with automatic adjustment compensates for the deflection of the roll shafts over the large widths of 2048–4060 mm, maintaining the roundness accuracy along the entire length of the shell, including at the maximum widths of the 3R 08-3040 and 3R 20-4060 models.

• Maximum plate capacity 30 tonnes on the 3R 20-4060 model — the capacity to process plates of up to 30 tonnes makes the WyRoll 3R 20-4060 3-roll plate rolling machine one of the largest rolling machines in the UZINEX portfolio, covering heavy industrial applications in the shipbuilding and oil industries.

The WyRoll 3R versus the WyRoll 2R — when to choose the 3-roll system

The WyRoll 2R Series with 2 rolls eliminates the residual straight zones at the plate ends — a decisive advantage when every millimeter of material counts. The WyRoll 3R Series with 3 rolls offers superior rolling accuracy (±0,08 mm versus ±0,5 mm), greater capacity at the same installed power and a smaller minimum diameter (200 mm versus 250 mm on the similar models), but accepts small straight zones at the plate ends that require pre-rolling or trimming.

The WyRoll 3R Series 3-roll plate rolling machine is the choice when the roundness accuracy of the shell (±0,08–0,1 mm) is critical for the vessel's quality standards — PED (Pressure Equipment Directive), ASME, EN 13445 applications — and when the 30-tonne capacity and the 4060 mm width are needed for the format of the designed tank or shell.

Applications and industries for the WyRoll 3R Series 3-roll plate rolling machine

The WyRoll 3R Series 3-roll plate rolling machine is intended for manufacturers of PED-certified pressure vessels, industrial tanks, heat exchangers and shells for the oil, chemical, energy and shipbuilding industries. The ±0,08 mm accuracy and the 42CrMo shafts guarantee compliance with European quality standards for the cylindrical components of pressure equipment.

Manufacturers of industrial boilers and steam generators use the 3R 08-3040 and 3R 20-4060 models of the 3-roll plate rolling machine for rolling shells made of high-temperature-resistant steel, where the ±0,1 mm accuracy on diameters of 900–4000 mm ensures the tightness of the welded joints without additional machining.

Steel-construction companies that produce cylindrical support columns, silos, storage tanks and offshore structures find in the WyRoll 3R Series a 3-roll plate rolling machine with the 30-tonne capacity and the 4060 mm width needed for the large-diameter sections of heavy industrial structures.

How the WyRoll 3R Series 3-roll plate rolling machine works

1. Automatic feeding and centering — the plate is fed automatically and centered with ±0,5 mm accuracy by the HIWIN pneumatic system before it enters the rolling zone, ensuring the correct alignment of the shell axis relative to the programmed axis.

2. Plate-end pre-rolling — the plate ends are successively pre-rolled to eliminate the residual straight zones specific to 3-roll systems; the operator selects the pre-rolling parameters from the 30 programs stored in the CNC.

3. Progressive rolling with variable flow — the variable-flow hydraulic system applies the rolling pressure proportional to the actual requirement; the plate advances progressively through the forming zone at a speed of 5 m/min, with continuous pressure correction on the 3–5 axes of the CNC system.

4. Deflection compensation through CNC lateral support — the CNC lateral support system automatically compensates for the deflection of the shafts at large widths, maintaining the rolling accuracy of ±0,08–0,1 mm along the entire length of the shell.

5. Shell completion and removal — when the programmed diameter is reached, the top roll is hydraulically raised; the automatic feeding system assists the removal of the finished shell, ready for welding and inspection.

Frequently asked questions about the WyRoll 3R Series 3-roll plate rolling machine

Why 42CrMo shafts instead of standard carbon steel?

42CrMo alloy steel, after heat treatment, offers a tensile strength of 900–1100 MPa versus 400–600 MPa for standard carbon steel, with increased surface hardness through hardening. On the WyRoll 3R Series 3-roll plate rolling machine, the 42CrMo shafts maintain the cylindrical geometry under the high loads of rolling thick 8–20 mm plates, without plastic deformation or premature wear of the contact surface with the plate.

How many programs can the CNC system of the WyRoll 3R Series store?

The CNC system of the WyRoll 3R Series 3-roll plate rolling machine stores 30 complete rolling programs, including all parameters: the shell diameter, the plate thickness, the number of passes, the pre-rolling parameters and the deflection corrections. This covers the complete range of standard products of a tank or vessel manufacturer, with instant recall without manual re-entry.
