HDLW11-150X3200 hydraulic symmetrical 3-roll plate rolling machine

Key Advantages of HDLW11-150X3200 Hydraulic Symmetrical 3-roll Plate Rolling Machine

- Hydraulic power system: The main cylinder of the HDLW11-150X3200 hydraulic symmetrical 3-roll plate rolling machine delivers 150 tons of rolling force, suitable for high-strength plate processing.
- Symmetrical three-roll structure: Torque is synchronously transmitted to lower rolls via a gear distribution box, reducing plate slippage.
- Digital position display: Upper roll displacement is shown in real time, assisting operators in controlling bending accuracy on the HDLW11-150X3200.
- Overload protection: The hydraulic system is equipped with a relief valve, preventing operation beyond the rated capacity of the HDLW11-150X3200.

Product Specifications of HDLW11-150X3200 Hydraulic Symmetrical 3-roll Plate Rolling Machine

The HDLW11-150X3200 hydraulic symmetrical 3-roll plate rolling machine features a maximum plate thickness of 150mm for cold bending of Q235 material and a maximum plate width of 3200mm. The upper roll diameter is approximately 560mm, while the two lower rolls each measure approximately 480mm in diameter. Rolling speed is rated at approximately 4 meters per minute. The machine is powered by a 45kW hydraulic motor and dual 37kW main drive motors. The symmetrical rolling method positions the upper roll centrally above the two lower rolls, effectively reducing the flat end length on processed plates. The wear-resistant roll surface is induction-hardened to achieve a surface hardness of HRC45-50. An independent hydraulic tank is equipped with a cooling circulation system to maintain optimal oil temperature within range. These specifications make the HDLW11-150X3200 hydraulic symmetrical 3-roll plate rolling machine a reliable choice for heavy-duty industrial forming.

Application Scenarios of HDLW11-150X3200 Hydraulic Symmetrical 3-roll Plate Rolling Machine

The HDLW11-150X3200 hydraulic symmetrical 3-roll plate rolling machine is widely used in the following applications: pressure vessel shell rolling, wind tower conical section forming, large-diameter pipeline prefabrication, ship hull curved plate processing, and heavy machinery structural component bending.

Common Issues and Solutions for HDLW11-150X3200 Hydraulic Symmetrical 3-roll Plate Rolling Machine

Issue 1: Plate slippage during rolling
Possible causes: Mill scale or oil contamination on plate surface; reduced friction coefficient due to lower roll surface wear.
Solution: Clean the plate surface before rolling on the HDLW11-150X3200 hydraulic symmetrical 3-roll plate rolling machine; inspect roll surface condition and resurface or replace rolls if necessary.

Issue 2: Out-of-tolerance cylindrical roundness
Possible causes: Upper roll penetration not compensated for material springback; insufficient rolling passes or uneven feed.
Solution: Pre-test springback amount based on material grade and thickness, and compensate penetration accordingly on the HDLW11-150X3200; use multiple incremental passes with curvature measurement after each pass.

Issue 3: Rapid hydraulic oil temperature rise
Possible causes: Incorrect hydraulic oil viscosity grade; insufficient cooling circulation flow or clogged radiator.
Solution: Replace with recommended viscosity grade (typically HM46 anti-wear hydraulic oil); clean the cooler and check circulation pump operation.

Operational Precautions for HDLW11-150X3200 Hydraulic Symmetrical 3-roll Plate Rolling Machine

- The HDLW11-150X3200 hydraulic symmetrical 3-roll plate rolling machine requires a concrete foundation with a levelness tolerance of 0.5mm per meter.
- Supply voltage fluctuation should not exceed ±10% of rated voltage.
- Check hydraulic oil level before each start-up; maintain level above mid-scale of the sight glass.
- Do not exceed specified plate thickness or width limits.
- Operators must receive plate rolling machine training and be familiar with the emergency stop button location.
