Hot strip mill lubrication leads to two essential effects: the reduction of the rolling power and the improvement of the rolled product (surface and texture). To characterise hot rolling lubrication, several actions have been carried out at lab, pilot and industrial scale. The results obtained have led to a re-thinking of the lubrication concept in order to simplify its application. Plate-out results obtained on emulsion application show that too many factors interfere with the interaction between oil and roll surface. Moreover, the unstable emulsion possible amelioration is highly counterbalanced by the drawbacks of this technique. Pilot tests confirm these results and highlight the influence of the roll 'situation' (top or bottom). At the industrial scale, even if some improvements of the lubrication process are possible, it seems difficult to reach, with emulsion, the consistency requested by a high quality production. Considering this situation, the HSM lubrication concept has been re-thought with, as a consequence, the testing and development of pure oil atomisation. This technique has given really promising results in terms of lab test (high and constant plate-out efficiency and homogeneous repartition). Moreover, pilot tests have shown a good friction lowering at a very low level of theoretical plate out, a high consistency and a good flexibility. Finally, this application allows the use of natural and efficient 'green' oils. The necessity to develop and study this technique appears clear. In this sense, a new RFCS programme will start in July 2004 aiming at the development of the application of pure oil.
