The rolling mill bearing been used to hot and cold rolling mill widely

Jul 31, 2023

As we all know, the rolling bearing is widely used on hot rolling mill and cold rolling mill line. FV bearing is a professional rolling mill bearing manufacturer, and FV bearing are widely used in CCM, CSP, Bar mill, FLAT MILL and Hot / Cold rolling mills.

Hot rolling is carried out the re-crystallization temperature of the rolling stock. Depending on the product, a distinction is made between plate, hot strip, section, bar, and wire mills. The angular adjustment of the chocks in rolling mills allows the use of four-row tapered roller bearings and multi-row cylindrical roller bearings as radial bearings. The design of the radial bearings depends on the application: Angular contact ball bearings for rapidly rotating rolls under low axial load, double-row tapered roller bearings and axial spherical roller bearings for bearing locations subjected to high axial loads.

In the cold rolling process, cold strip is generally shaped without prior heating. In comparison with the hot rolling process, higher dimensional accuracy and surface quality together with smaller sheet thicknesses are achieved. Four-row cylindrical roller bearings fulfill the high demand for precision, even in high-speed rolling mills for aluminum. In multi-roll mills for stock that is difficult to roll, cylindrical roller bearings are used as back-up roller systems and ensure uniform sheet thickness and surface quality under extremely high loads. 

Below is the four-row cylindrical roller bearing we supply to our steel customer, the model is 340RYL1963B.C2. see the picture of bearing and drawing:

Ladle turrets

A ladle turret carries ladles between the casting position and the tapping position, thus ensuring smooth operation of the continuous casting plant. The bearing supports are continually subjected to high loads as well as abrupt shocks and tilting moments. The cylindrical roller bearings, axial spherical roller bearings, and spherical plain bearings are designed specifically for these loads.

Continuous casting plants

In this essential forming process, steel is continuously cast through a mold to form a strand. During the cooling phase, the strand is transported and supported by slowly rotating rollers. The bearing supports for the rollers must function reliably under high loads, at high temperatures, and when subjected to water spray. Sealed bearings allow the grease volume to be reduced by as much as 80%. 

The full complement cylindrical roller bearing advantageous:

• Extremely high radial load carrying capacity

• Axial displacement without constraining forces

• Capable of compensating angular mis-alignments

• Simple and quick to mount
