Resumo
Light meter is an ArcelorMittal innovation that uses off-gas light intensity to predict bath carbon, which is akin to the visual cues that the operators employ to finish a blow. Light meter enables the prediction of end point that is independent of any operator’s judgment. The results have been in general consistent with the actual carbon content at BOF end point at Tubarão. Besides some outliers that occurred due to strange intensity curves, the system implemented in Tubarão BOF 3 reported a carbon prediction error statistic that is very similar to dissolved oxygen–carbon end point statistics. Preliminary trials using light meter without any filter improved carbon hit ratio significantly.
