Application and advantages of oil film-bearing bushings in rolling mills

Jan 22, 2024

In the steel smelting industry, oil film-bearing bushings are mainly used in key parts of rolling mill equipment, such as the support rolls of rolling mills and the bearings of operating side rolls. These parts need to withstand huge pressure and friction, so they have high requirements on the wear resistance and stability of the bearings. The rolling mill is an important piece of equipment for metal rolling. Its performance and stability have a decisive impact on the quality and efficiency of rolled products. With the continuous advancement of industrial technology, oil film-bearing bushings are increasingly used in rolling mills. This article will discuss the advantages of oil film-bearing bushings in rolling mills, their impact on rolling mill performance, and the factors that should be considered when selecting.

1. Application advantages of oil film-bearing bushings in rolling mills

Support and guide function: During the rolling process, the oil film-bearing bushing is crucial in supporting and guiding the rolled piece through multiple passes until it reaches the expected shape and size. The oil film-bearing bushing can withstand the huge pressure brought by the rolling stock and ensure the stable operation of the rolling mill. At the same time, it can also guide the rolling stock to move according to the predetermined trajectory to ensure the smooth progress of the rolling process.

Optimize the rolling process: The lubrication performance of the oil film bearing bushing enables it to form a uniform oil film during the rolling process, effectively reducing the contact area between the rolled piece and the bearing and reducing frictional resistance. Maximize your rolling mill's potential with our cutting-edge technology. Our solutions optimize the rolling process, reduce rolling force, and improve rolling efficiency. Don't settle for less - upgrade to our innovative system today.

Improve product quality: The stable performance of the oil film-bearing bushing and the reduced friction coefficient make the rolling mill more stable during operation, reducing the impact of heat generated by vibration and friction on the rolled products. Enhancing the surface quality and dimensional accuracy of rolled products allows you to cater to the growing market demand for high-quality products easily.

Adapt to high-load working conditions: With the continuous development of rolling technology and increased production capacity, the load endured by rolling mills is also increasing. Our oil film bearings are fantastic for handling heavy loads and high speeds, making them perfect for intense working conditions. With their exceptional stability, you can trust a smooth and reliable operation for your rolling mill.

Energy saving and environmental protection: Oil film-bearing bushings can reduce energy consumption and friction loss in rolling mills, enhancing mechanical efficiency. At the same time, due to its excellent lubrication performance and small friction coefficient, it can effectively reduce the consumption of lubricating oil and reduce environmental pollution.

Easy Maintenance: Oil film-bearing bushings are easier to maintain than traditional bearings. Its simple design and compact structure make installation and disassembly easier and faster. In daily maintenance, you only need to regularly check the wear and lubrication status of the bushings and promptly make necessary adjustments and replacements to ensure the smooth rotation of the rolling mill.

High reliability: The oil film-bearing bushing uses high-quality materials and high-precision manufacturing technology, which has high reliability and stability. The complex rolling process can effectively reduce the probability of failure and improve the overall reliability of the rolling mill.

Strong adaptability: Oil film-bearing bushings have strong environmental adaptability and can work stably under different temperatures, humidity, and pressure conditions. It allows it to meet the operating needs of rolling mills in various climates and working conditions.

Economy: Although the initial investment of oil film-bearing bushings may be higher due to their long life, low maintenance costs, and high reliability, they have good economics in long-term use. Oil film-bearing bushings have lower overall costs and higher benefits than traditional bearings.

2. When selecting rolling mill oil film-bearing bushings, the following factors need to be considered:

Bearing specifications: Select the appropriate bearing specifications based on the specific needs of the rolling mill. The specifications mainly involve the diameter of the working surface (outer circle) of the taper sleeve and the aspect ratio series of the bearing. Understanding the aspect ratio is important in rolling mill oil film bearings. It's the ratio between the length of the bushing and the taper sleeve's outer diameter. "Acquiring this knowledge will ensure that your machinery performs optimally and lasts longer."

Wear resistance: Due to the harsh working conditions in the steel smelting industry, it is necessary to select oil film-bearing bushing materials with good wear resistance.

Load-bearing capacity: To ensure optimal performance, the rolling mill demands an oil film-bearing bushing with a robust load-bearing capacity to withstand significant pressure and torque during operation.

Stability: The stability of oil film-bearing bushings is critical to ensuring the smooth operation of the rolling mill. Choosing an oil film-bearing bushing that can remain stable under various operating conditions is necessary.

Maintenance and maintenance methods: In the steel smelting industry, the maintenance and upkeep of equipment are very important. By selecting oil film-bearing bushings that are low maintenance and easily serviced, you'll save money and improve equipment dependability.

In summary, applying oil film-bearing bushings in rolling mills has significant advantages. It has excellent performance in supporting and guiding, reducing friction and wear, optimizing the rolling process, improving product quality, adapting to high-load working conditions, energy saving and environmental protection, easy maintenance, high reliability and strong adaptability. These advantages make oil film-bearing bushings an ideal choice in rolling mills, providing strong support for the sustainable development of the rolling industry. In the future, with the continuous innovation of technology and the expansion of application fields, oil film-bearing bushings will be more widely used in rolling mills, bringing greater value to industrial manufacturing.
