Oil-Air Lubrication for Coiler Bearings in Hot Rolling Mills
Release time:
2021-09-23
The coiler is an important piece of equipment at the end of many hot rolling lines. It receives and coils the finished strip after rolling, operating under continuous mechanical loads and high rotational speeds.
The bearings and rotating components inside the coiler require reliable lubrication to maintain stable operation and consistent strip handling.
Why Coiler Bearings Need Reliable Lubrication
Coiler bearings may operate under:
- High rotational speed;
- Heavy mechanical loads;
- Repeated acceleration and deceleration;
- High ambient temperature;
- Vibration and impact;
- Cooling water and scale;
- Continuous production conditions.
These conditions place high demands on the lubrication system.
Insufficient lubrication can increase friction, wear and temperature. Excessive lubrication may increase lubricant consumption and heat generation.
Oil-Air Lubrication for Coiler Components
An oil-air lubrication system supplies accurately metered oil to suitable coiler bearing positions.
The lubricant is transported with compressed air through dedicated pipelines. Depending on the equipment configuration, several lubrication points can be supplied from a centralized station.
Oil-air lubrication can provide:
- Precise lubricant dosing;
- Continuous or scheduled oil delivery;
- Supporting cooling for rotating components;
- Reduced excessive lubricant accumulation;
- Reduced manual lubrication requirements;
- Centralized system control;
- Lubrication pressure and oil-level monitoring.
For high-speed rotating equipment, precision lubricant delivery is particularly important because the objective is not to use more lubricant, but to supply the appropriate quantity required by the bearing.
Intelligent Lubrication Monitoring
For modern steel mills, lubrication can be integrated with automatic monitoring.
Huashun centralized oil-air systems can be configured with pressure sensors, oil-level monitoring, distributor monitoring, PLC control and alarm functions.
If abnormal pressure, insufficient oil supply or other system faults occur, the lubrication system can provide an alarm according to the configured control logic.
This helps maintenance teams identify lubrication problems before they develop into more serious equipment issues.
Customized Coiler Lubrication Engineering
Every rolling line has different coiler structures and operating parameters. Therefore, the lubrication system should be engineered according to the actual equipment.
Huashun evaluates:
- Bearing configuration;
- Rotational speed;
- Mechanical load;
- Operating temperature;
