ABSTRACT:
A method for cooling and lubricating rolls and/or the rolled material in cold rolling of metal strips in a rolling mill stand. The method includes supplying emulsifiers as necessary and emulsions which contain at least one oil phase. The emulsion is prepared immediately in front of the rolls of the rolling mill stand or immediately in front of the strip inlet into the rolling gap formed by the work rolls by separately supplying the media which form the emulsion. Subsequently, the emulsion is collected behind the rolling mill stand and the emulsion is broken up and the liquid phases are separately processed and reused for forming the initial emulsion.
