Industrial facility comprising a contactless wiper

An industrial facility, comprising:

• at least one work cylinder, the at least one work cylinder being configured to convey at a surface thereof a first liquid comprising a cooling liquid and/or lubricant jet or stream;
• a contactless wiping system comprising a nozzle bar configured to be placed along a width of the work cylinder and separated, in use, by a determined interval with respect to the work cylinder;
• a liquid recovery trough;
• and
• a rolling mill cage for metal strips comprising at least one pair of work rollers and at least one cooling device spraying a plurality of pressurized jets on at least one of the rollers owing to a plurality of nozzles making up a cooling bar, wherein the at least one pair of work rollers comprises the at least one work cylinder,
• wherein the nozzle bar is configured so as to supply, in use, a jet comprising a liquid curtain comprising a second liquid that is different from the first liquid in a direction that is substantially opposite a scrolling direction of the strip or a rotation direction of the work cylinder so that the second liquid sprayed by the nozzle bar deflects the jet or stream of the first liquid driven by the strip or by the work cylinder in order to form a combined stream comprising the first liquid and the second liquid that moves away from the strip or the work cylinder to fall back into the liquid recovery trough and to allow the removal of the combined stream so as to minimize the combined stream being further driven by the strip or the work cylinder downstream from the wiping system,
• wherein the interval is between 3 and 10 mm,
• wherein a flow rate of the second liquid sprayed by the nozzles of the wiping system is between 10 and 200 m3/h,
• wherein a pressure of the sprayed second liquid is between 0.5 and 5 bars,
• wherein the wiping system is proximal relative to a roll gap of the work rollers, and
• wherein the cooling bar is distal relative to the roll gap.
