Aug 25, 2015· To further understand the impact of roll lubrication, a trial was performed which yielded the mechanism and advantages of backup roll lubrication in the reversing hot rolling mill: – Fewer roll changes are needed with lubricated backup rolls, as the normal pressure and friction traction between the backup and work rolls are reduced, which ...
Especially in hot rolling mills, roller tables have to withstand the presence of water and scale as well as high temperatures. SKF can help mills keep roller tables moving despite these harsh conditions. SKF solutions can help reduce maintenance and lubrication costs, and keep product moving for less.
