The oscillation actuator is a critical component of the continuous casting mold oscillation table system, responsible for producing the precise, controlled back-and-forth motion of the mold. This motion is essential for preventing the solidifying steel shell from sticking to the mold walls, ensuring smooth billet/slab withdrawal, improving surface quality, and facilitating lubrication. The actuator converts input energy, typically hydraulic pressure or electric motor torque, into a controlled linear or rotary oscillatory motion. This motion is transmitted to the mold table via linkages or a direct drive mechanism. The stroke length, frequency, and waveform (e.g., sinusoidal, non-sinusoidal) are precisely controlled according to casting parameters. Typical operating parameters include an operating pressure of 1.0–1.6 MPa, a stroke length of 50–200 mm, a frequency range of 0.5–3.0 Hz, an amplitude of 2–10 mm, a maximum load capacity of 10–50 t, positioning accuracy of ±0.05 mm, supply voltage of 380–480 V AC (per IEC 60038), power consumption of 5–15 kW, operating temperature of -10 to 60 °C, ingress protection of IP54–IP65 (per IEC 60529), material QT500-7 (per GB/T 1348), and weight of 500–1500 kg. These values are reference ranges and must be verified for the specific model and application. The actuator is typically made of alloy steel or high-strength cast iron. For procurement, confirm the exact specifications with the legal manufacturer or supplier, and verify compliance with relevant standards. The actuator is designed for use in basic metal manufacturing, specifically in continuous casting processes. It is a component, not a standalone machine, and its selection depends on mold size, casting speed, and load requirements. Proper installation, maintenance, and monitoring are essential to ensure reliable operation and to avoid failures such as seal leakage, bearing wear, or loss of positioning accuracy.

The stroke length, frequency, and waveform (e.g., sinusoidal, non-sinusoidal) are precisely controlled according to casting parameters. The control system adjusts these parameters to match the casting speed and mold size, ensuring optimal oscillation for the solidifying steel shell. The actuator operates within specified limits, such as operating pressure, frequency, and load capacity, to maintain performance and prevent damage.
