Why customized Steel rolling mill production line production requires the quality of roll bearings
The customized Steel rolling mill production line is the mechanical equipment that realizes the metal rolling process, and generally refers to the equipment that completes the whole process of rolling material production. Including main equipment, auxiliary equipment, lifting and transportation equipment and auxiliary equipment. The working unit consists of rolls, roll bearings, racks, rail seats, roll adjustment devices, upper roll balance devices and roll changing devices. Roll bearings in rolling mills are important components for supporting the rolls and keeping them in the correct position in the stand.
The friction coefficient of the bearing is related to the rolling energy consumption; the service life of the bearing is related to the utilization rate of the rolling mill; the stiffness of the bearing has a certain influence on the dimensional accuracy of the rolled product. Therefore, the production of customized Steel rolling mill production line equipment requires that the roll bearing should have a small friction coefficient, sufficient strength and a certain rigidity. In modern rolling mills, the structural shape of the roll bearing also facilitates rapid roll changing operations. The roll bearing is used to support the rotating roll and is an important part in the working stand of the rolling mill. The quality of its assembly, adjustment and maintenance has a direct impact on the bearing life, product dimensional accuracy and rolling mill operation rate. Many early damaged roll bearings are not a quality problem per se, but are caused by improper installation and lack of good maintenance. Maintenance work is a arduous and meticulous systematic project involving numerous expertise in rolling process, hydraulics, machinery, etc. Careful maintenance and strict management are of great significance to prolonging the life of the bearing and exerting good performance.
The customized Steel rolling mill production line supports the rolls and maintains the fixed position of the rolls in the frame. The working load of the roll bearings varies greatly, so the bearing friction coefficient is required to be small, with sufficient strength and rigidity, and it is necessary to facilitate the replacement of the rolls. The rolling mill uses different types of roll bearings.
