The main aim of the project was the development of a new sensor-based control technology for operating pickling lines. Pickling is the most important step to remove surface scale layers and is strongly dependent on the exactly controlled pickling liquor composition. When the project started, there was no feasible system available for online control of pickling lines. Within this project, new methods for online analysis of the pickling liquors were tested and implemented into pickling process control. As a result of this, the pickling line staff will be enabled to control the process with all the up-to-date process knowledge they need. Work started with the assessment of actual operating situations of pickling lines and the definition of optimum pickling process parameters. Operational and laboratory trials were performed to determine suitable sensor applications. Data acquired from those trials with operational and artificial pickling solutions were investigated for mathematical modelling. Sensors were developed and the establishment of communication between different modules of process control was considered. In order to apply sensors on site, operational measurements were performed. Suitable processes and locations were fixed for future installations. Finally, the partners reviewed optimum pickling process parameters to programme the aspired process control. The results achieved were verified in comprehensive operational trials.
