Method and device for lubricating rollers and a rolled strip of a rolling stand

A method for lubricating rolls of a rolling stand and rolling stock passed between the rolls during the rolling operation, comprising the steps of:

• applying a lubricant-water mixture to the rolls or the rolling stock on a run-in side of the rolling stand:
• preparing the mixture with at least one mixing device in an area upstream of the rolling stand, including conveying water and at least one lubricant to a mixer through separate supply lines and mixing the water and lubricant in the mixing device to form a water-lubricant dispersion or emulsion, and wherein the water-lubricant dispersion or emulsion is atomized in atomizing nozzles using a gas, wherein the gas conveys the dispersion or emulsion through a line from the mixer to a respective one of the atomizing nozzles where the dispersion or emulsion is applied by the gas to at least one of the work rolls and/or to the rolling stock, and wherein the atomizing nozzles are arranged over a width of the at least one of the work rolls and/or the rolling stock;
• and
• providing each of the atomizing nozzles with a control valve for individually controlling the amount of the atomized lubricant dispersion or emulsion applied by the gas to the at least one of the work rolls and/or the rolling stock.
