ABSTRACT:
A method for efficiently operating a steel rolling mill employing oil-in-water emulsions as lubricants which includes controlling the stability of the emulsion within certain preselected limits and correlating the oil concentration to a mean time (t.sub.m) of such values. The mean time is determined through an emulsion stability index test and constitutes the time required for the concentration of oil in emulsion samples to drop to 50% of its original value.
