cold rolling mills
the main component, is in high speed and high precision cold rolling system process of main components to guarantee, since new century 80 time, mill with four row cylindrical roller bearing has been widely used in non-ferrous plate metallurgical industry companies, There are also many doubts about the precise application and application handling in practical activities. It is mainly about how to develop the effective life limit of four row cylindrical roller bearings for cold rolling mill and how to reduce its harm to the precision of rolling material. This point on the construction of copper strip production and processing enterprises, small and medium-sized copper strip production and processing enterprises and copper strip greatly expanded but all kinds of application method and technology is not good, reflect the enterprise, especially excellent.
Due to the weak foundation of the comparison of this kind of enterprise technology, the understanding of four-row cylindrical roller bearings used in cold rolling mills is relatively shallow, and there are many doubts in the machine equipment, application and application of four-row cylindrical roller bearings used in cold rolling mills. Composition of rolling bearing life limit is short, cold rolled goods often suffer from rolling bearing doubt harm, so that the probability of machine and equipment firm opening, machine and equipment maintenance cost, maintenance staff labor efficiency have suffered great harm.
Therefore, how to improve the accurate understanding of four row cylindrical roller bearings used in cold rolling mill, the effective application and application of four row cylindrical roller bearings used in cold rolling mill seems to be more and more urgent. According to the summary of practical experience in copper processing enterprises, there are mainly some doubts in the process of application and application management system of four-row cylindrical roller bearings used in cold rolling mills.
① The cold rolling mill with four row cylindrical roller bearings and general rolling bearings are treated equally, there is no special application method.
② Random cutting of other user groups in the rolling bearing circle, damage the bearing clearance.
③ Rolling bearing machinery and equipment are rude, slanting and dragging, and rude prying.
④ Smooth and clean is not standard, especially about thin oil smooth and clean way, too smooth and clean is not optimistic.
⑤ Casually match with rolls and seat bearings, and the precision of backlash is reduced.
⑥Rolling bearing maintenance is not timely, the application method is not appropriate.
⑦ There is no accurate matching scheme and backlash standard for rolling bearings of new machinery and equipment.
⑧Rolling bearings into the factory inspection, inspection is unreasonable.
⑨ Heavy machine equipment is not optimistic, and the life limit of rolling bearing decreases.
