Why bearings are important to the smooth operation of rolling mill equipment

May 15, 2023

In the metallurgical industry, bearings are indispensable and important accessories. And the consumption of the bearing is very large. Therefore, the steel industry has very strict quality requirements for bearings. Once the bearings have quality problems or there is not enough stock, it will cause the shutdown of the entire production line, which is unbearable for steel mills. For rolling mills, especially for hot rolling mill and cold rolling mill production lines, the stable operation of the rolling mill is the most important.

Hot rolling mill is carried out above 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 in version F12 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.

Wire rod block and laying head adopt special cylindrical roller bearings, angular contact ball bearings, and spindle bearings.
