The company has a five 1450mm 8-rolls rolling mill from CERI.
Bearing configuration is as follows:
BUR - NNCF41104240
IMR - FC3448170
WR - 82728
The bearing of the support roller is a large P4 - grade bearing with high precision, which requires high manufacturing level and rich manufacturing experience.
In this continuous rolling mill, because the 4 rack has the characteristics of large rolling force and fast speed relative to other stander, the accuracy of bearing is also the highest. For this purpose, only new bearings are allowed to use the new bearing, and the repaired bearing and the longer time bearing are not allowed to be used on the machine No. 4. And strictly according to the maintenance cycle (about 30 days) to carry out the maintenance.
For making our production supporting roller bearing on the No. 4 stand on the 50 days of continuous operation, machine maintenance throw in good condition.
