Measures to Improve the Operating Efficiency of High-Speed Rolling Mills

High-speed rolling mills, similar to conventional rolling mills, aim to obtain the required specifications and dimensions of rolled products through rolling. In order to enhance the operational efficiency of high-speed rolling mills during the rolling process, corresponding improvement measures are necessary.

The operational efficiency of high-speed rolling mills is often affected by unplanned shutdowns, delays in other equipment, replacement of rolling rolls and bearings, and maintenance of other processes. Therefore, to improve the operating rate of high-speed rolling mills, planned measures need to be implemented. The specific steps include:

Selecting rolling roll materials based on the requirements of rolled products to improve the fatigue strength and service life of rolling rolls.

Periodically inspecting the wear of rolling rolls and guide positions.

Reversing the lubricating oil injection process for bearings, changing from internal to external injection, to reduce dust pollution on bearings.

Using ultrasonic technology to inspect and analyze rolling rolls.

Modifying the dry lubrication points, adding dry oil from the high-pressure zone, increasing the addition frequency from every six cycles to every eleven cycles of raw materials, and adjusting the thin oil lubrication to a 15-minute cycle. These cumulative changes can result in a few degrees Celsius reduction in bearing temperature.

As the steel rolling industry undergoes industrial upgrades, new challenges arise. Accordingly, it is essential to continuously optimize and adjust the steel rolling process based on actual conditions. This process requires a step-by-step and long-term exploration.
