Working Principle:

Controls the input and output of high-pressure hydraulic oil through a servo valve to drive the piston within the cylinder, moving the rolling roll; a built-in high-precision displacement sensor (e.g., magnetostrictive sensor) provides real-time position feedback, forming a closed-loop control system with the AGC system. It adjusts the roll gap to compensate for rolling disturbances, achieving precise and stable strip thickness control.

Compact & High-Power Design:

Features an integrated structure (with built-in sensors and low-friction seals), capable of delivering ultra-high rolling force (up to 40,000 kN) within a compact cylinder size. This design fits the limited space in rolling mill stands, combining high power density with excellent spatial efficiency.

Simple Integration:

Directly interfaces with the rolling mill’s AGC control system and roll mechanism, eliminating the need for complex intermediate transmission components. This reduces transmission backlash and signal delay, simplifying system commissioning and maintenance.

Limited Stroke:

Stroke is mechanically constrained by the roll gap adjustment requirements of the rolling mill (typically 50–120 mm). Combined with high-precision positioning control, it ensures accurate and safe roll gap adjustments.

Mounting Options:

Offers multiple mounting configurations (e.g., flange type, hinge shaft type) to match various rolling mill stand interfaces (hot rolling, cold rolling, plate rolling mills), and supports customized shaft ends and connection structures.

Typical Applications:

Metallic Rolling Mills: Roll gap control in hot strip finishing mills, thickness adjustment in cold rolling pickle lines, and precise screw-down operations in plate rolling mills.

Strip Processing Lines: Roll gap adaptation in skin pass mills on galvanizing/tinning lines, and tension roll pressure adjustment in color coating lines.

Non-Ferrous Metal Rolling: High-precision thickness control in aluminum/copper plate rolling mills.
