A new technology for lubricating the work rolls during hot rolling has been successfully tested in the finishing mill of ArcelorMittal Dunkirk. This new technology allows spraying very low quantities of pure oil on the work rolls to reduce the rolling forces by up to 20% and with an increased efficiency of 50% compared with emulsions. The lubricant was a pure natural oil without any additives.
Résumé
Une nouvelle technologie de lubrification des cylindres lors du laminage à chaud a été testée avec succès dans le train finisseur d’ArcelorMittal Dunkerque. Cette nouvelle technologie permet de pulvériser de toutes petites quantités d’huile pure sur les cylindres pour réduire les forces jusqu’à 20 %, avec une efficacité augmentée de 50 % comparée avec celle utilisant des émulsions. Le lubrifiant était une huile naturelle pure sans additions.
