HIGH-PICKProject reference: RFSR-CT-2005-00021
Funded under: ECSC-COAL-STEEL-RTD C
Optimised productivity and quality of pickling by on-line control of pickled surface
Total cost:EUR 1 652 096
EU contribution:EUR 991 258
To attain a complete elimination of the oxide from the steel surface is an obvious quality request of pickling. However the over-pickling i.e. the attack of iron by the acid solution is also detrimental in terms of productivity and quality. So reaching the exact "just pickled" state is an important issue. That is precisely the objective of this project.
It will have a multidisciplinary approach:
- Development / adaptation of a number of sensors: to monitor the strip surface, follow the process and assess the aggressiveness of the acid solution
- On-line tests in several industrial lines
- Statistical analysis of overall pickling phenomena.
All the data will be used to define the conditions assuring optimised operation i.e. full pickling and no or minimal over-pickling. Finally the benefits will be analysed and the transfer conditions will be prepared.
