Abstract: An industrial facility includes: a metal strip in motion; and/or at least one work cylinder; a contactless wiping system of a cooling liquid and/or lubricant jet or stream driven by a surface of the metal strip in motion or the work cylinder, the wiping system including a separating cleat with integrated supply of cooling liquid ending with a nozzle bar to be placed along a width of the metal strip or the cylinder and separated, during use, by a determined interval with respect to the metal strip or the work cylinder, the nozzle bar being oriented so as to supply a jet in a for of a liquid curtain oriented along a direction that is substantially opposite a scrolling direction of the strip or a rotation direction of the cylinder; and a liquid recovery trough, oriented such that during use, liquid sprayed by the nozzles deflects the jet.

Abstract: The present invention relates to a lubrication method in a hot-rolling mill by means of a lubricant comprising used oil, said used oil at least partly stemming from waste coming from a cold-rolling mill.

Abstract: The present invention relates to an installation for the in-line lubrication of rolling cylinders (1), preferably for hot rolling of a metal strip, which is preferably steel, by spraying or atomizing a lubricant over a target comprising said cylinders and/or said strip, preferably in the vicinity of the roll gap, by means of a bar (2) of controllable air sprays (3), arranged in parallel to said cylinders (1) and supplied with compressed air or inert gas (4), wherein each spray (3) comprises an inlet for the compressed air or inert gas (4) and an inlet for uncompressed pure oil (5) in an adapter (6) followed by a mixing chamber (6?) as well as an outlet nozzle (7) for the atomized mixture.
