It is well known that the quality control of cold rolling oil is very important. In order to keep quality of strip surface, coolant and iron concentration of cold rolling oil, and coating oil value were measured by chemical analysis. But it was not enough to keep quality. Because it needed long time and was not often carried out. So management on-line analyzers for cold rolling oil have been developed, consisting of fully automatic coolant concentration measuring system, magnetic balance system and coating oil analysis system. Coolant concentration measuring system : After the cold rolling oil was resoluted by acid addition and was centrifugal separated, and the surface oil measured by picture treatment method. Iron concentration analysis system : The iron concentration was measured by the magnetic balance method. Coating oil analysis system : After irradiate the ultraviolet rays for a sheet, measure the fluorescence from coating oil. These newly developed on-line analyzers have greatly contributed to the improvement of quality control and the decrease of operators loads of the cold strip mill operation.
