Industrial facility comprising a contactless wiper

An industrial facility, comprising:

• 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 comprising a separating cleat with integrated supply of cooling liquid ending with a nozzle bar intended configured 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 comprising 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, configured such that during use, liquid sprayed by the nozzles deflects the jet or stream of liquid and/or lubricant driven by the strip or by the cylinder in order to form a combined stream of liquid or mixture of liquid and lubricant that moves away from the strip or the roller to fall back into the recovery trough and to allow the removal of the combined stream, practically without any more liquid and/or lubricant being driven by the strip or the cylinder downstream from the wiping system,
• wherein the interval is between 3 and 10 mm,
• wherein a flow rate of the liquid sprayed by the nozzles is between 10 and 200 m3, and
• wherein a pressure of the sprayed liquid is between 0.5 and 5 bars.
