Abstract (en)
[origin: CA2671230A1] The invention relates to a method and a lubricant application device (100 ) for regulating the planarity and/or roughness of a metal strip (400) in th e run-out of a cold rolling stand by suitable metering of the amount of at l east one lubricant per unit of time applied to the metal strip (400) in the run-in of the cold rolling stand. To further improve the quality of cold-rol led metal strip with regard to its planarity and/or roughness, it is propose d according to the invention that the applied amount of lubricant is metered in the form of a distribution of the quantity over the width of the metal s trip per unit of time in accordance with an established deviation between an actual planarity distribution and a set planarity distribution over the wid th of the metal strip in the run-out of the cold rolling stand or a deviatio n between an actual roughness distribution and a set roughness distribution over the width of the metal strip in the run-out of the cold rolling stand ( 100) or a combination of the two deviations.
