AGC Mill Working Roll Metallurgical Servo Bending Cylinder: Precision Control for Modern Rolling Mills

AGC (Automatic Gauge Control) Metallurgical Servo Bending Cylinder

In modern metal rolling mills—especially in cold and hot strip production—precise control of strip thickness and flatness is critical. At the heart of this precision lies the AGC (Automatic Gauge Control) metallurgical servo bending cylinder, a high-performance hydraulic actuator designed specifically for working roll bending applications.

These cylinders are integral components of AGC systems, which automatically adjust roll gap in real time to maintain consistent product thickness. The servo bending cylinder applies controlled bending forces to the working rolls, counteracting deflection caused by rolling loads. This dynamic adjustment ensures uniform strip profile, minimizes edge waves or center buckles, and significantly improves product quality.

Features

• High rigidity construction using forged alloy steel to withstand extreme pressures (typically up to 28 MPa or 4,000 PSI)
• Servo-quality sealing and guidance systems for low friction, long life, and resistance to iron oxide scale, coolant, and vibration
• Integrated mounting for position sensors (e.g., LVDT or magnetostrictive transducers) enabling closed-loop control with repeatability down to ±0.01 mm
• Fast response rates (5–10 Hz) compatible with high-speed servo valves for real-time roll bending adjustments

Commonly specified with bore sizes from 160–250 mm, rod diameters like 128 mm, and strokes ranging from 80–200 mm, these cylinders are fully customizable for OEM integration into reversing mills, tandem stands, or temper mills.

By delivering exceptional accuracy, reliability, and responsiveness, AGC metallurgical servo bending cylinders play a vital role in boosting yield, reducing scrap, and enabling the production of high-grade steel, aluminum, and specialty alloys demanded by today’s advanced manufacturing sectors.
