Mold Oscillation Servo Hydraulic Cylinder

Precision Drive – Core Solution for Superior Casting Performance

Key Technical Advantages
Uranus mold oscillation servo cylinders provide ultra-high precision and fast dynamic response for modern continuous casting. With electro-hydraulic direct drive and fully integrated digital control, amplitude, frequency, and waveform skew can be tuned online without shutdown. The cylinder ensures precise negative slip arc oscillation, improving lubrication and preventing sticking.

Product Features

● High precision control: Micron-level amplitude; millisecond frequency response
● Dual oscillation modes: Supports sinusoidal and non-sinusoidal waveforms
● Independent strand control: Multi-strand CCMs with per-strand parameter tuning
● Smart connectivity: MES/expert system integration for remote monitoring, diagnostics, predictive maintenance
● Rugged & reliable: Long service life, low maintenance, stable under harsh conditions
