Hydraulic & Electrical Rotary Joints
(Customized Products for Ladle Turret Applications)

In steelmaking ladle turrets, hydraulic and electrical rotary joints are critical components ensuring continuous and safe operation.
They allow high-pressure fluids such as hydraulic oil, lubricants, cooling water, and gases to be transferred from stationary piping to rotating equipment, while also maintaining uninterrupted power and signal transmission.
Hydraulic rotary joints utilize advanced rotary sealing and multi-channel fluid transfer technology to achieve continuous delivery of high-pressure fluids between stationary and rotating platforms.
Electrical slip rings use precision silver-alloy contacts to ensure reliable transmission of power and signals.
When integrated together, these systems form a comprehensive “multi-media transmission channel” — the lifeline of automated steelmaking operations.
Tianjin Uranus Hydraulic Machinery Co., Ltd.
Specialized in manufacturing hydraulic rotary joints, electrical slip rings, high-pressure hydraulic cylinders, and servo actuators.
Customized design and drawing services are available upon request.

Working Principle
The hydraulic rotary joint is composed of a ​rotating housing​ and a ​stationary shaft core.The shaft connects to fixed pipelines, while the rotating housing moves synchronously with the turret, transmitting high-pressure fluids through sealed multi-channel paths. This ensures leak-free, long-life performance even under extreme operating conditions.
The electrical slip ring uses silver-alloy contacts and low-noise conductive paths to maintain continuous transmission of power, control, and sensor signals with low resistance fluctuation and high anti-interference capability.

Key Advantages
1. High-precision sealing – Multi-layer sealing ensures zero leakage under high pressure.
2. Precision manufacturing – CNC machining guarantees concentricity and sealing surface accuracy.
3. Low torque & smooth rotation – Reduces energy consumption and extends lifespan.
4. Full-scale testing – Every unit undergoes pressure, electrical, and durability testing before delivery.
URANUS has delivered over a thousand customized rotary joints to global metallurgical enterprises, with many operating continuously in harsh environments for more than 20 years.
