Full complement roller bearings on continuous casting machines

Jan 30, 2024

Continuous casting machines are essential equipment in the steel industry. Its function is to cast high-temperature molten steel into billets of various specifications continuously. In this process, bearings serve as important supporting components of the continuous casting machine, and their performance directly affects the stability and production efficiency of the continuous casting machine. Among them, full complement roller bearings have been widely used in continuous casting machines due to their simple structure, high load-bearing capacity, and high-temperature resistance.

Structure and characteristics of full complement roller bearings

Full complement roller bearings are mainly composed of inner rings, outer rings, rollers, cages, and other parts. The inner ring is connected to the rollers of the continuous casting machine, and the outer ring is connected to the bearing seat. Rollers are rolling elements in bearings, and their number and arrangement vary according to different bearing models. The function of the cage is to keep the rollers at a certain distance and prevent the rollers from colliding with each other and getting stuck.

Full complement roller bearings are characterized by a more significant number of rollers and a higher filling factor, which means the bearing has a more robust load-bearing capacity. At the same time, due to the large number of rollers, the load on each roller is smaller, which can reduce the wear of a single roller and increase the service life of the bearing. In addition, full complement roller bearings have a simple structure, are easy to install, and have low maintenance costs.

Application of full complement roller bearings in continuous casting machines

On continuous casting machines, full complement roller bearings are mainly used to support and guide the cast slabs. Specifically, they are installed in the slab guide to guide and position the slab accurately. During this process, the bearings need to bear large radial and axial loads, as well as high temperatures and water erosion. Choosing the appropriate full complement roller bearing is crucial for the stable operation of the continuous casting machine.

In order to improve the bearing capacity and durability, some special process measures are also used in the production of full complement roller bearings. Using high-carbon chromium bearing steel as the primary material for the bearing can enhance its hardness and wear resistance. Exceptional heat and surface treatments are used to enhance bearing corrosion and fatigue resistance. They use an optimized design to maintain frame and roller shapes and reduce bearing friction and wear.

Maintenance and maintenance of full complement roller bearings

Although full complement roller bearings have high load-bearing capacity and durability, correct maintenance and upkeep are still the keys to ensuring their long-term stable operation. The following are some suggestions for the maintenance and care of full complement roller bearings:

Regularly check the operating status of the bearings: By monitoring the active sound, vibration, temperature, and other parameters of the bearings, abnormal conditions of the bearings, such as wear or looseness, can be discovered in time. Once an abnormality is found, it should be handled promptly.

Regular Lubrication: Lubrication is critical to the life of a full complement roller bearing. Bearings should be lubricated regularly according to the bearing manufacturer's recommendations and using a suitable lubricant. Insufficient lubrication can cause increased bearing wear, while too much lubrication can cause bearings to heat up and seize.

Please keep it clean: The environment around the continuous casting machine is usually harsh, with a lot of dust and impurities. In order to prevent contaminants from entering the bearing and causing wear or jamming, the bearing and its surrounding environment should be cleaned regularly.

Replace damaged bearings in time: It is essential to replace severely worn or damaged bearings promptly. Long-term operation may cause damaged bearings to cause more significant damage or affect the regular operation of other components.

In short, the application of full complement roller bearings on continuous casting machines is of great significance to the stable production and improvement of production efficiency of steel enterprises. Through reasonable selection, correct installation and maintenance, and timely maintenance and replacement, the long-term regular operation of full complement roller bearings on continuous casting machines can be ensured.

FV Company can also produce full complement roller bearings, as well as other bearings for continuous casting machines, such as tapered roller bearings, spherical roller bearings, etc.
