Product Specifications

Technical details and manufacturing context for Oscillation Table

Definition

The oscillation table is a critical component of the continuous casting mold oscillation system in steel manufacturing. It serves as the structural foundation that supports the mold assembly while imparting precise vertical oscillatory motion to prevent sticking of the solidifying steel shell to the mold walls. This controlled movement ensures uniform heat transfer, reduces friction, and improves surface quality of the cast product. The table is typically constructed from high-strength steel and heat-resistant alloys to withstand the harsh thermal and mechanical environment of continuous casting. It is designed to accommodate a range of operating parameters, including oscillation frequency of 50–180 min⁻¹, amplitude of 2–10 mm, and load capacity of 10–50 t. Stroke accuracy is maintained within ±0.1 mm to ensure consistent mold movement. The operating pressure is specified as 1.0–1.6 MPa, and the power supply is 380 V AC ±10% (IEC 60038). The table operates within an ambient temperature range of 0–60°C, and its ingress protection rating is IP54–IP65 (IEC 60529). The material of construction is typically Q235B carbon steel with hardened guide rails (GB/T 700). The weight of the table varies from 1500 to 3000 kg, depending on load capacity and stroke. These values are reference ranges and must be verified for the specific model and application with the legal manufacturer or supplier. The oscillation table is an integral part of the mold oscillation system, and its proper selection and maintenance are essential for achieving high-quality steel products.

Working Principle

The oscillation table operates through hydraulic or electromechanical actuators that convert rotational or linear input into controlled vertical oscillations. These oscillations follow specific waveform patterns (typically sinusoidal or non-sinusoidal) with adjustable amplitude and frequency to match casting parameters. The table's rigid construction ensures precise motion transmission to the mold while withstanding high thermal and mechanical loads. The frequency and amplitude are set based on casting speed and steel grade to optimize the strand surface and minimize mold wear. The table's load capacity must match the combined weight of the mold and tundish to avoid overloading. Stroke accuracy is critical for uniform oscillation, and any deviation may lead to uneven shell formation. The operating pressure and power supply must be within specified ranges to ensure reliable actuator performance. The table is designed to operate within a temperature range of 0–60°C; above 60°C, hydraulic seals may be affected. The ingress protection rating indicates resistance to dust and water jets, which is important in the casting environment.

Frequently Asked Questions

What is the primary function of an oscillation table in continuous casting?

The oscillation table supports the mold and imparts controlled vertical oscillations to prevent the solidifying steel shell from sticking to the mold walls. This ensures uniform heat transfer and improves surface quality.

What are typical oscillation frequency and amplitude ranges?

Typical frequency ranges are 50–180 min⁻¹, and amplitude ranges are 2–10 mm. These values are adjustable to match casting parameters and must be verified for the specific application.

What materials are commonly used for oscillation tables?

High-strength steel and heat-resistant alloys are used for structural components. The material specification may include Q235B carbon steel with hardened guide rails, as per GB/T 700.

What maintenance signals indicate potential issues with the oscillation table?

Signs include increased vibration, abnormal noise, deviation in stroke accuracy, or hydraulic fluid leaks. Regular inspection of seals, guide rails, and actuators is recommended. Operating temperature above 60°C may affect hydraulic seals.
