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.

Hot Strip Mills Stability of the hot strip mill roll-ing process remains a main topic when it comes to processing thin and hard materials. Strip steering, especially at the end of rolling and tail-out rips, is a main source of unscheduled downtimes in a hot strip mill (HSM). The main focus of this paper is the new X-Roll® Guide system to ...

The state-of-the-art of both technology and operation practice of a hot al rolling mill are discussed. The focus is first on the control of entry temperature in the finish mill. Transfer bar cooling and induction heating are presented. Next the safe keeping in the, finishing mill of surface quality, crown and flatness are discussed.

Again, slower rolling speeds, coupled with thin gauge strip and the temperature loss associated with the use of lubrication, could make this coiling temperature impossible to achieve on a conventional hot strip mill.For the hot rolling of strained IF grades, it would be beneficial to both product and hot mill productivity to …

The application of oil lubrication in hot strip rolling has many advantages for the process, i. e., reduced roll force, reduced energy consumption, better strip surface quality, and reduced roll wear.On the other hand, oil lubrication may also induce severe disturbances for several control loops in a tandem hot rolling mill, which can reduce the …

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.New lubrication technology for the hot strip mill,,27-01-2010· New lubrication technology for the hot strip mill The use of ...

Hot rolling experiments have been conducted, using low carbon steel strips. The effects of water, oil/water emulsions, neat oil and dry conditions at the roll/strip surface, on the resulting loads and temperatures were examined. The 1 : 1000 oil-to-water mix appeared to lower the mill loads the most. Doubling the oil volume was found to have a ...

To reduce roll wear and chatter vibrations in its hot strip mill, Eko Stahl carried out roll gap lubrication trials. The trial equipment, the lubricant and the trials themselves are described. Rolling force and consequently electric energy consumption were reduced by 8 to 34 % . ... New lubrication technology for the hot strip mill Revue de ...
