Good quality bearings suppliers are important for rough rolling

Oct 11, 2023

In steel rolling production, bearings are an important part of the rolling mill. Especially in the rough rolling stage, bearings play a vital role. The following will elaborate on the use, maintenance, and common problems of bearings in the rough rolling stage.

The use of bearings in the rough rolling stage

Support and guide role: During the rough rolling stage, bearings serve as key support and guide components and bear huge radial and axial loads. Since the rolling mill has high accuracy requirements under high-speed operation, the accuracy and stability of the bearings directly affect the quality and efficiency of the rolling process.

Withstand impact loads: During the rough rolling process, the metal blank is subjected to high-stress rolling effects, and the bearings need to withstand the resulting impact loads. In order to ensure that the bearings can withstand this harsh working environment, bearings with strong load-bearing capacity and impact resistance are usually selected.

Thermal expansion and cooling: During the operation of the rolling mill, the bearings will be affected by high temperatures and cause thermal expansion. At the same time, in order to prevent the bearings from overheating and damage, they need to be cooled. Therefore, the selection of bearings with good thermal stability and heat resistance is crucial to ensure the smooth progress of the rough rolling process.

Maintenance of bearings during the rough rolling stage

Inspection and replacement: In order to ensure the normal operation and service life of the bearings, they need to be inspected regularly, including whether the bearing seats, bearing caps, fasteners, and other parts are loose or damaged. If problems are found, the bearings need to be replaced or the damaged parts repaired in time.

Lubricant selection and addition: Bearing lubricants can reduce friction, prevent wear, and prolong the life of bearings. During the rough rolling stage, since the bearings bear a large load, lubricants with higher viscosity should be selected, lubricant consumption should be checked regularly, and lubricants should be added in time to maintain good operation of the bearings.

Vibration detection: By using vibration detection instruments to monitor and analyze the vibration data of the bearing during operation, potential problems with the bearing can be discovered early. Vibration detection instruments can reflect the operating status of bearings in real time, detect signs of bearing failure in a timely manner, and help preventive maintenance and extend the service life of bearings.

Common problems and solutions for bearings in the Roughing Mill Rolls stage

Bearing seat wear: Due to the friction between the bearing seat and the bearing outer ring, the bearing seat will wear. The solution is to use wear-resistant materials to make the bearing seat or surface harden the bearing seat to improve wear resistance.

Bearing overheating: During the rough rolling process, due to the excessive load on the bearings, it is easy to cause the bearings to overheat. The solution is to install a cooling device in the bearing seat or use bearing materials with good heat resistance.

Vibration and noise: If the bearing clearance is too large or the lubrication is poor, vibration and noise will occur. The solution is to adjust the bearing clearance, optimize the lubricant selection and addition method, select low-noise bearings, and other measures to reduce vibration and noise.

Poor sealing: Due to the failure of the sealing device between the inner and outer rings of the bearing, impurities such as dust and moisture will enter the inside of the bearing, affecting the normal operation of the bearing. The solution is to use high-performance seal materials, regular inspection and maintenance of seals, and other measures to improve the sealing performance of the bearing.

In short, bearings play a key role in the rough rolling stage of steel rolling production. Correct selection, use, and maintenance of bearings are crucial to improving rough rolling quality and production efficiency. At the same time, effective solutions to common problems can extend the service life of bearings and ensure the smooth progress of the rolling process.

Choosing high-quality bearing suppliers is crucial to the production and operation of the company, mainly in the following aspects:

Ensure production efficiency and product quality: High-quality bearings can improve the stability and accuracy of equipment, thereby ensuring the improvement of production efficiency and product quality. If the bearing quality is not up to standard, it may cause unstable equipment operation, affect the smooth progress of the production plan, and even lead to an increase in product defective rates.

Reduce maintenance and replacement costs: Choosing high-quality bearings can extend their lifespan, reduce maintenance frequency, and prevent premature replacement, thereby reducing the company's operating costs. Poor-quality bearings can lead to frequent repairs and replacements, adding additional costs to the business.

Ensure production safety: Bearings are one of the key components in mechanical equipment. If the quality is not up to standard, it may lead to equipment failure, production accidents, and other problems. Choosing high-quality bearings can reduce the risk of equipment failure and ensure the production safety of the enterprise.

Improve corporate credibility: Choosing high-quality bearing suppliers can enhance the credibility and image of the company and enhance customers' trust in the company. It will help improve the market competitiveness of enterprises and expand business cooperation opportunities.

Ensure the stability of the supply chain: Choosing a bearing supplier with long-term cooperation and stable supply capabilities can ensure the stability of the company's supply chain and avoid production disruptions caused by insufficient or unstable bearing supply.

To sum up, choosing a high-quality bearing supplier is crucial to the production and operation of an enterprise. When selecting bearing suppliers, companies should consider the supplier's qualifications, reputation, service capabilities, and other factors and conduct full investigations and comparisons to ensure that a suitable bearing supplier is selected, thereby creating a lasting and stable business for the company.
