Steel mills operate under some of the harshest industrial conditions in the world. Continuous high temperatures, heavy loads, water contamination, scale dust, and shock loads place extreme demands on bearing lubrication. Selecting the right high temp bearing grease for steel mill equipment is not only critical for bearing life, but also directly affects production uptime, maintenance costs, and overall plant reliability.

Aleman Moil develops and supplies high temperature bearing grease specifically engineered for steel mill environments, helping maintenance teams reduce unplanned downtime and extend bearing service intervals under extreme heat conditions.

Why Steel Mills Require Specialized High Temperature Bearing Grease

Bearings in steel plants face operating conditions far beyond standard industrial applications. Conventional greases often fail prematurely due to:

• Continuous exposure to temperatures above 180°C

• Peak temperature spikes during rolling, reheating, or casting processes

• Heavy radial and axial loads

• Water spray, steam, and cooling fluids

• High levels of dust, scale, and metal particles

A steel mill grade high temp bearing grease must maintain structural stability, lubrication film strength, and resistance to oxidation even when exposed to extreme heat and contamination.

Aleman Moil high temperature bearing grease is designed to remain stable where standard lithium greases soften, bleed excessively, or carbonize.

Typical Steel Mill Equipment Requiring High Temp Bearing Grease

Steel pro/duction involves multiple high-heat zones, each with unique lubrication challenges. Aleman Moil grease is widely used in bearings for:

• Hot rolling mill bearings

• Continuous casting machine bearings

• Reheating furnace conveyor bearings

• Walking beam furnace bearings

• Slab and billet transfer roller bearings

• Cooling bed fan and roller bearings

• Sinter plant equipment bearings

• Coke oven conveyor and fan bearings

Each of these applications requires a grease that can operate reliably under prolonged thermal stress while maintaining load-carrying capacity.

Operating Temperature Performance

Aleman Moil high temp bearing grease for steel mills is formulated for:

• Continuous operating temperatures: up to 200–220°C

• Intermittent peak temperatures: up to 280–300°C

• Excellent thermal recovery after temperature cycling

• Low oil separation at elevated temperatures

This ensures consistent lubrication even during production peaks, start-stop cycles, and emergency overload conditions common in steel plants.

Thickener Systems and Base Oil Technology

Steel mills require grease formulations that do not melt, run off, or harden under heat. Aleman Moil offers multiple formulation options to match different mill requirements:

Thickener Options

• Lithium complex for balanced performance and cost efficiency

• Calcium sulfonate complex for superior load and water resistance

• Polyurea for excellent oxidation resistance and long service life

• Specialty non-melting systems for extreme heat zones

Base Oil Options

• Highly refined mineral oils

• Synthetic base oils for extended temperature stability

• Low volatility formulations to reduce oil evaporation

This flexibility allows procurement and engineering teams to select the most suitable grease based on operating temperature, bearing speed, and contamination exposure.

Load Carrying and Anti-Wear Protection

Steel mill bearings often operate under heavy loads and shock conditions. Aleman Moil high temperature bearing grease provides:

• Strong lubricating film under high pressure

• Excellent EP (Extreme Pressure) performance

• Effective anti-wear protection for rolling and sliding contacts

• Reduced metal-to-metal contact during startup and high-load events

This translates into longer bearing life and fewer unexpected failures in critical production equipment.

Resistance to Water, Steam, and Contamination

Water ingress is unavoidable in steel mills due to cooling systems and environmental exposure. Aleman Moil grease is engineered to:

• Maintain consistency in the presence of water and steam

• Resist washout and emulsification

• Protect bearings against corrosion and rust

• Maintain adhesion to bearing surfaces

This is especially critical for continuous casting lines, cooling beds, and outdoor equipment.

Oxidation Stability and Extended Relubrication Intervals

High temperatures accelerate oxidation, causing grease hardening and deposit formation. Aleman Moil high temp bearing grease is designed with:

• High oxidation resistance

• Minimal carbon residue formation

• Stable structure during long-term heat exposure

As a result, steel mills can achieve longer relubrication intervals, reducing grease consumption, labor costs, and maintenance downtime.

Compatibility with Existing Greases

For steel mills planning grease replacement or optimization programs, Aleman Moil provides guidance on:

• Compatibility with common lithium and lithium complex greases

• Safe transition procedures during changeover

• Minimizing risk during grease consolidation projects

This supports smooth implementation without disrupting ongoing operations.

Bulk Supply and Industrial Packaging Options

Aleman Moil supports steel mills and industrial distributors with flexible supply solutions:

• Bulk supply for centralized lubrication systems

• Drums and pails for maintenance departments

• OEM and private label options for large-volume users

• Stable production capacity for long-term supply agreements

Reliable availability is essential for steel plants operating 24/7 production schedules.
