WyRoll 2R Series Plate Rolling Machine

The WyRoll 2R Series is a high-capacity 2-roll plate rolling machine, with high-pressure hydraulic drive and a CNC control system with 3D programming, available in 5 configurations, from the 2R120 (12 mm/2000 mm) to the 2R300 (30 mm/4000 mm), designed for manufacturers of tanks, pressure vessels, shells, large-diameter pipes and industrial cylindrical structures. With dual heat-treated drive rolls (HRC 58–62), a Bosch Rexroth hydraulic system at 28 MPa and a rolling accuracy of ±0,5 mm, this plate rolling machine covers the complete range of industrial rolling applications from thin 12 mm plates up to thick 30 mm plates in widths up to 4000 mm.

The 2-roll system of the WyRoll 2R Series plate rolling machine ensures uniform compression along the entire length of the roll through the direct contact of both rolls with the plate throughout the rolling process, without the residual straight zones at the plate ends specific to 3- or 4-roll systems that require additional pre-rolling. The hydraulic diameter compensation integrated into the CNC system automatically calculates and applies the corrections needed to achieve the programmed diameter.

Key advantages of the WyRoll 2R Series plate rolling machine

• High-capacity dual rolls HRC 58–62: 50 tonne load. The dual drive rolls heat-treated to a hardness of HRC 58–62 with Fabreeka USA support ensure high durability and long-term geometric accuracy, with a load capacity of up to 50 tonnes for processing thick plates up to 30 mm in widths up to 4000 mm.

• Bosch Rexroth hydraulic system at 28 MPa: 25% more efficient. The Bosch Rexroth Germany high-pressure hydraulic unit at 28 MPa ensures constant rolling pressure along the entire length of the roll, with 25% higher energy efficiency than conventional hydraulic systems at equivalent pressures.

• CNC with hydraulic diameter compensation and 3D programming: the CNC system automatically calculates and applies the hydraulic diameter compensation for each order, with 3D programming of cylindrical and conical shapes and complete storage of rolling programs, eliminating dependence on highly experienced operators for setting the parameters.

• Rolling accuracy ±0,5 mm across the entire width: the WyRoll 2R Series plate rolling machine maintains a rounding accuracy of ±0,5 mm across the entire width of the roll, from 2000 mm to 4000 mm depending on the model, ensuring that the resulting shell or cylinder meets the tolerances imposed by the project without subsequent adjustment operations.

• Minimum rolling diameter 250 mm on the small models: the minimum rolling diameter of 250 mm on the 2R120 and 2R150 models allows the production of small-diameter cylinders, extending the range of applications compared with machines with large-diameter rolls that cannot reach small internal diameters.

• Optional lateral and top support system: large plates. The optional lateral and top support for large-dimension materials ensures the stability of the plate during the rolling of bulky, heavy parts, preventing the deformation or imbalance of the material on the large 2R260 and 2R300 models.

• 5 models: widths from 2000 mm to 4000 mm. The WyRoll 2R range covers any standard metal plate format for the production of shells and industrial vessels, from the medium 2000 mm formats to the extra-wide 4000 mm formats specific to high-volume vessels.

Applications and industries for the WyRoll 2R Series plate rolling machine

The WyRoll 2R Series plate rolling machine is intended for manufacturers of pressure vessels, industrial tanks, shells for boilers and heat exchangers, large-diameter pipes and cylindrical structures for the oil, chemical, food and energy industries. The rolling capacity of up to 30 mm thickness over the 4000 mm width (the 2R300 model) covers all European standards for pressure vessels in the PED category.

Manufacturers of equipment for the shipbuilding industry use the WyRoll 2R Series plate rolling machine for the production of shells and cylindrical components of ship hulls and offshore structures, where naval-steel plate thicknesses of 20–30 mm and widths of 3000–4000 mm are standard specifications. The ±0,5 mm accuracy ensures that the resulting shells meet the roundness tolerances imposed by naval inspection standards.

Companies in the wind energy industry that produce wind-tower sections use the large 2R260 and 2R300 models of the plate rolling machine for rolling high-strength steel plates into large-diameter shells, with the CNC 3D programming system ensuring the correct shape of the conical and cylindrical tower sections.

How the WyRoll 2R Series plate rolling machine works

1. CNC program setup with diameter compensation: the operator enters the desired cylinder diameter into the CNC system; the automatic hydraulic compensation calculates the pressure and position parameters needed to achieve the programmed diameter, taking into account the specific elasticity of the material.

2. Plate positioning between the rolls: the metal plate is fed between the dual rolls of the plate rolling machine; the optional lateral and top support stabilizes large-dimension materials on the 2R260 and 2R300 models.

3. Progressive rolling with 28 MPa hydraulic pressure: the Bosch Rexroth hydraulic system applies the rolling pressure constantly along the entire length of the rolls; the plate advances progressively through the forming zone at a speed of 5 m/min, with both rolls in continuous contact with the material across the entire width.

4. Automatic hydraulic correction: the CNC system continuously monitors and corrects the hydraulic pressure on both rolls to compensate for variations in plate thickness and material elasticity, ensuring uniform roundness around the entire circumference of the cylinder.

5. Shell closing and removal: after the programmed diameter is reached, the plate ends meet for welding; the top roll is hydraulically raised to release the formed cylinder, with the lateral support assisting the removal of heavy parts.

Frequently asked questions about the WyRoll 2R Series plate rolling machine

What is the advantage of the 2-roll system over 3- or 4-roll systems?

3- or 4-roll systems leave straight zones at the plate ends that require separate pre-rolling or the acceptance of material waste at each end. The WyRoll 2R Series plate rolling machine with a dual system practically eliminates the residual straight zones through the continuous contact of both rolls with the plate throughout rolling, reducing material losses and eliminating separate pre-rolling operations. The disadvantage compared with 3–4 roll systems is that the maximum processable thicknesses are smaller at the same roll diameter.

What materials can the WyRoll 2R Series machine roll?

The WyRoll 2R Series plate rolling machine processes carbon steel, stainless steel, aluminum and non-ferrous alloys. For harder materials (stainless steel, high-strength alloys), the maximum rolling thickness is smaller than the nominal capacity on mild carbon steel. UZINEX provides consultancy for verifying the rolling capacity on the customer's specific material before model selection.
