ABSTRACT
Study of the degraded emulsions characteristics during rolling thin strips of steel, has an
important role in determining the valorizations’ methods of these waste and for reducing
environmental pollution. The emulsion system is crucial in the production of cold rolled
steel strips, having an important role in the process of lubrication, cooling and cleaning.
The paper characterized emulsions depending on their wear degree. Were analyzed
physical - chemical properties (viscosity, density, pH, turbidity, chemical composition)
of different emulsions beginning the initial state and during use rolling technological
process as well as impure products assimilated during rolling. Based on the
experimental results have proposed some valorizations methods of the emulsions used
in cold rolling steel strip.

Keywords: properties, emulsion, rolling, steel strip
