Novel externally enhanced pickling improvement for short/mid term (Nextep)
Publication metadata
The purpose of this project was to develop and then to evaluate boosting techniques to accelerate pickling in existing pickling lines. The three techniques under study were AC processing, dynamic control and remote cavitation. The final objective was the processing of difficult-to-pickle grades without decreasing while keeping the same speed and thus high productivity. A collateral intended benefit was the reduction of the environmental impact of pickling. The three boosting techniques were investigated at various levels. At first, each of them was developed and tested in the laboratory. Then, all the techniques were tested in one common pilot rig, using the same samples. This common testing enabled very objective comparisons as well as the analysis of possible combinations. Several partners took part in the common tests. The main results of the investigations have been summarised by means of pickling time improvement. Moreover the application of each boosting technique has been considered in a very practical way: space needed, cost evaluation, energy consumption. This gives the tools to select one possible boosting technique depending on the amount of difficult-to-pickle steel grades, the space constraints and the availability of energy. The specific costs and savings have been quantified, in order to give as precise as possible industrial guidelines.
