A new method for lubricating the work rolls during hot rolling has been successfully tested on the finishing mill of ArcelorMittal Dunkerque.
The technology sprays low amounts of unemulsified natural oil without additives onto the work rolls using air atomisation,lowering the rolling forces by up to 20% and increasing efficiency of use of oil by 50% in comparison with emulsions.
