Paper Abstract

In the cold rolling of steel sheet, oil-in-water emulsions are used to provide lubrication and cooling. Both the concentration and the quality of the oil involved must be carefully controlled in order to produce an acceptable product. Current analytical procedures usually involve separation of the oil from the water, followed by analysis of the different components by various wet chemical and instrumental methods. In principle, attenuated total reflection FT-IR spectroscopy offers the possibility of obtaining much or all of the required information from one measurement made directly on the emulsion. This paper describes some preliminary results involving the use of ATR spectroscopy to determine the percentage of oil in a clean emulsion. Although the use of ATR for aqueous solutions is well known, its applicability to emulsions has been less widely studied. In particular, the heterogeneous nature of emulsions could cause problems not encountered with aqueous solutions.
