Oil-Air Lubrication for High-Speed Finishing Block Bearings

Release time:

2021-11-22

The finishing block is one of the most important sections of a high-speed wire rod mill. During continuous rolling, the finishing block operates at extremely high rotational speeds, while its internal bearings are exposed to high loads, vibration and heat. Stable bearing lubrication is therefore essential for maintaining rolling accuracy and production efficiency.

Lubrication Challenges in Finishing Blocks

High-speed finishing block bearings require a precise and continuous lubricant supply. Excessive grease may cause churning, heat accumulation and increased running resistance. However, insufficient lubrication can result in friction, wear, overheating and premature bearing failure.

Because the finishing block usually operates continuously, manual lubrication is difficult to control and may not provide consistent lubrication at every bearing position.

How Oil-Air Lubrication Works

An oil-air lubrication system delivers a small and accurately controlled quantity of oil to the bearing through compressed air. The oil is metered by distributors and transported to the lubrication point in a stable oil-air flow.

This lubrication method can provide:

Continuous delivery of fresh lubricant;
Accurate oil supply according to bearing requirements;
Reduced excessive lubricant accumulation;
Supporting cooling from compressed air;
Reduced risk of water, dust and scale entering the bearing housing.

Huashun Oil-Air Lubrication Solution

Huashun designs oil-air lubrication systems according to the finishing block structure, bearing type, rotational speed, load, temperature and number of lubrication points. The system can include an oil-air main station, oil-air distributors, pipelines, control cabinet, PLC and monitoring devices.

With centralized control and lubrication monitoring, operators can better understand the operating condition of the lubrication system and respond to abnormal pressure, oil level or distributor signals in time.

For high-speed finishing blocks, precision oil-air lubrication is an effective approach to supporting bearing reliability and reducing lubrication-related maintenance.
