In smelting operations, hydraulic systems do more than drive motion—they directly impact process stability and operational safety.
For equipment such as tilting furnaces, ladle cars, and pouring systems, every movement must remain predictable under high load and extreme environmental conditions.

Industry Context: High Load and Safety-Critical Operations

Smelting environments impose demanding conditions on hydraulic systems:

High temperature and radiant heat
Dust and contamination
Continuous heavy-duty operation

Typical risks during operation include:

Loss of torque during furnace tilting, causing unstable molten metal levels
Unstable lifting or travel of ladle cars under load
Inconsistent motion in pouring systems during continuous cycles

These scenarios require not only sufficient power but also stable and predictable hydraulic performance.

Core Requirement: High Pressure, Large Flow, Long-Duration Stability

Compared with general industrial equipment, smelting systems demand:

High working pressure to support heavy loads
Large displacement to ensure sufficient flow
Stable output under long-duration continuous operation

This places stricter requirements on the main hydraulic pump, especially in safety-critical applications.

Solution Platform: FG2 High-Pressure Internal Gear Pumps

For these conditions, FG2 internal gear pumps are widely adopted as the main hydraulic power source.

Key Technical Parameters

Displacement range: approximately 64.7–162.8 mL/r
Rated pressure: 31.5 MPa
Maximum pressure: up to 35 MPa

These parameters provide sufficient capacity for tilting, lifting, and pouring operations under heavy load.

Structural Advantages

Internal gear design with inherently low pulsation
Stable volumetric efficiency under high pressure
Better tolerance to oil contamination compared with conventional pump designs

With proper filtration, FG2 pumps remain stable even in harsh smelting environments.

Performance Characteristics in Real Applications

In practical smelting projects, two aspects are particularly valued.

Predictability of Motion

Tilting furnaces and ladle cars maintain stable speed and pressure profiles throughout their operating range
Sudden slowdowns or pressure drops are minimized

Safety Margin Under High Pressure

Even during continuous heavy-duty operation, the system remains stable near its 31.5 MPa working pressure
This reduces risks associated with insufficient torque or pressure fluctuations

Engineering Value: Pump Selection as a Safety Component

In smelting applications, the hydraulic pump is not only a power source but also a critical safety element.

Selecting a pump with:

Large displacement
High pressure capability
Low pulsation
Tolerance to oil contamination

helps establish a stable hydraulic foundation for high-temperature and high-load operations.

Summary

For tilting furnaces, ladle cars, and pouring systems, hydraulic performance must remain stable under extreme conditions.

Using FG2 high-pressure internal gear pumps enables:

Reliable motion control under heavy load
Improved safety margin in high-pressure operation
Reduced sensitivity to environmental contamination
More consistent long-term system performance

In smelting workshops, a properly selected high-pressure pump is both a productivity tool and a key factor in operational safety.
