High-Torque Radial Piston Motor for Metallurgical Equipment

Overview

The High Torque Internal Radial Piston Hydraulic Motor is a robust solution designed to deliver exceptional torque in harsh metallurgical environments, ideal for rolling mills, continuous casters, and heavy-duty conveyors. Engineered with a compact radial piston design, this motor ensures reliable performance under extreme loads and temperatures.

Features

Extreme Load Capability:

Output torque up to 10,000 N·m at 200 bar, with speed range 0-200 RPM, capable of driving large-diameter rollers in steel production lines.

Radial piston configuration (8 pistons) for uniform force distribution, reducing shaft stress by 30% compared to axial designs.

High-Temperature Resistance:

Specialized seals (FKM with graphite impregnation) for 200°C continuous operation, with heat-dissipating fins reducing housing temperature by 15°C.

Case-hardened steel components (HRC 60) resistant to scaling and oxidation in furnace environments (≤1000°C radiant heat).

Low Maintenance Design:

Self-lubricating bronze bushings (oil-free operation for 500 hours), reducing downtime in hard-to-reach metallurgical equipment.

Integrated contamination resistance (NAS 1638 Class 7), with magnetic suction filters (10μm rating) for iron-rich hydraulic fluids.

Precision Control:

Zero-leakage design (≤50 mL/min at rated pressure), ensuring stable torque output in continuous casting machines requiring ±1% speed control.

Optional tachometer output (10-1000 Hz) for real-time speed monitoring in automated production lines.

Application

Ideal for metallurgical applications, this motor excels in:

Rolling Mills: Drives work rolls and pinch rolls in hot/cold rolling processes, withstanding 100°C ambient temperatures and scale particle exposure.

Continuous Casters: Powers mold oscillators and withdrawal systems, ensuring smooth slab movement (speed accuracy ±0.5%) in steel casting lines.

Slag Handling Equipment: Operates slag crushers and conveyors in steel plants, with abrasion-resistant coatings (WC-Co overlay) for long life in abrasive environments.

Aluminum Extruders: Provides consistent torque for billet feeding systems, supporting high-pressure extrusion (≥300 bar) of aluminum profiles.

FAQ

Q: What is the maximum particle size it can handle?

A: Designed for fluids with ≤50μm particles (ISO 4406 19/17/14), with optional pre-filters for higher contamination levels.

Q: Can it operate in vertical orientations?

A: Yes, fully bidirectional and suitable for any mounting position (horizontal, vertical, inclined).
