Application of Hot Rolling Lubricants to the Backup Rolls on Çolakoðlu Finishing Mill and the Comparison With General Work Roll Gap Lubrication Method

Çolakoglu’s hot strip mill (C HSM), which started up production in 2010, was capable of producing approximately 3.0 million tons per year of hotrolled coil. Since one-third of its production is materials less than 2 mm thick and steel market quality needs are getting higher consistently, C HSM has extended the rolling lubrication system, which was previously installed in F2•6 rolling stands in the first installation of the facility to all (F1•7) of the rolling stands in the first phase. Following that, C HSM has carried out backup lubrication experiments in accordance with many targets such as stability during rolling, improving product surface and profile quality, reducing energy consumption, increasing roller life, reducing roll consumption, and reducing roller change stops. Çolakoglu HSM has made a specific design for the backup roll lubrication and successfully applied it in both the early and late stands of the finishing mill (F1•7) and has achieved significant gains through implementation.
