hot mill roll lubrication systems

Abstract. To improve hot-steel-strip rolling mill operations trial attempts at work roll surface lubrication have been made by various investigators throughout the world during the last decade. Some European tests are briefly described. Most of the investigations have been somewhat inconclusive, possibly because they were not undertaken with ...

A new lubrication technology adapted by CRM based on the atomising of pure (natural) oil in very low quantities (0.4 g/m2) and good homogeneity has been tested in stand F2 of the hot strip mill in ArcelorMittal Dunkerque. Its implementation is the result of close cooperation between CRM, TKS, ArcelorMittal R&D (ARSA) and ArcelorMittal Dunkerque.
