Points to note when selecting bearings for the finishing rolling section

Mar 29, 2024

The finishing rolling section is a critical stage in the rolling process and is crucial for bearing selection. The finishing rolling section requires bearings with high precision, high stability, good wear resistance, and long life to ensure that the rolled products meet high-quality requirements. The following are some points to note when selecting bearings in the finishing rolling section:

First of all, the finishing rolling section requires extremely high precision for the bearings. Since the fine processing of metal materials is required in the finishing rolling stage, the accuracy of the bearings directly affects the dimensional accuracy and surface quality of the rolled products. Therefore, when selecting bearings, you need to pay attention to the manufacturing accuracy and installation accuracy of the bearing to ensure that it can meet the needs of the finishing rolling process. At the same time, the tolerance fit of the bearings also needs to be strictly controlled to avoid rolling errors caused by excessive tolerances.

Secondly, the finishing rolling section has high requirements for the stability of the bearings. During the finishing rolling process, parameters such as rolling force, rolling speed, and rolling temperature fluctuate less, which requires the bearing to maintain stable performance during long-term operation. Therefore, when selecting bearings, factors such as bearing structural design, material selection, and heat treatment process need to be considered to improve the bearing's rigidity and deformation resistance. In addition, the lubrication method of the bearing also needs to be selected appropriately to ensure that the bearing can maintain a stable working condition during high-speed operation.

Furthermore, the finishing rolling section has higher requirements on the wear resistance of the bearings. During the finishing rolling process, the bearings need to withstand high friction and wear, so the bearing materials need to have good wear resistance. When selecting bearings, consider using materials with excellent wear resistance, such as high-carbon chromium-bearing steel, ceramics, etc. At the same time, the surface treatment of the bearings also needs attention, such as using coatings, shot blasting, etc., to improve the wear resistance of the bearings.

In addition, the finishing rolling section also has certain requirements for the reliability and long life of the bearings. Since the finishing rolling process requires high quality and precision of rolled products, bearing failure or damage will directly affect the stable operation of the production line and product quality. Therefore, when selecting bearings, it is necessary to consider the reliability design of the bearing, such as using redundant design, strengthening the support structure of the bearing, etc. At the same time, the service life of the bearing is also a factor that needs to be considered. Through reasonable material selection, design, and maintenance, the service life of the bearing can be extended, and production costs can be reduced.

Finally, when selecting bearings for the finishing rolling section, you also need to pay attention to the maintenance and replacement of the bearings. Although the bearings in the finishing rolling section wear slower than those in the rough rolling section, regular maintenance and replacement are still necessary. When selecting bearings, you need to consider the maintenance cycle and replacement cycle of the bearing in order to develop a reasonable maintenance plan. At the same time, bearing replacement needs to be quick and easy to reduce downtime and production losses.

When selecting bearings for the finishing rolling section, attention should be paid to the accuracy, stability, wear resistance, reliability, and long life of the bearings. By rationally selecting the type, specification, and material of the bearing and paying attention to the maintenance and replacement of the bearing, the smooth progress of the finishing rolling process can be ensured, and product quality and production efficiency can be improved. In addition, establishing a good cooperative relationship with bearing suppliers and obtaining timely technical support and after-sales service for bearings are also key to ensuring the selection and use of bearings in the finishing rolling section.
