The 600,000-ton high-speed wire rod oil-air lubrication system of Kunyu Steel Co., Ltd. was contracted to Yantai Huashun Machinery Engineering Equipment Co., Ltd. Installation was completed in July 2013, and full production commenced in August.

The lubrication equipment configuration is as follows:

1. Roughing, intermediate rolling mills, and pre-finishing mills: Lubrication range 70 meters, lubrication points include: mill body, guides, loopers, brackets, etc., totaling 272 lubrication points. The lubrication equipment includes one main station, four substations, two sets of external air source treatment devices, and an oil-air distributor.

2. Finishing mill: Utilizing an imported Morgan mill, lubrication range 20 meters, lubrication points include guides, 22 lubrication points. The lubrication equipment includes one main station and an imported oil-air distributor.

3. Mini mill: Utilizing an imported mill, lubrication points include guides, 2 lubrication points. The lubrication equipment includes one main station and an imported oil-air distributor.

Lubrication Performance:

From trial run to full-load production, there were no accidents caused by bearing burnout or production stoppages due to insufficient lubrication. The work site is very clean, and the workload of workers is greatly reduced when replacing bearings. Inspection and maintenance are very convenient.

Transparent pipes are used at both the substation outlet and the lubrication point inlet, allowing for a clear view of the oil and air conditions. The operation process is simple and easy to understand, with a high degree of mechatronics integration, featuring a Siemens PLC and a Chinese touchscreen for convenient and intuitive operation. The equipment has a low failure rate and requires minimal spare parts inventory.
