Marcegaglia and Csm present to EU the project ACE-PICK. The innovative results of the AC electrolytic pickling process revealed.
The Gazoldo degli Ippoliti (Mantua - Northern Italy) HQ of Marcegaglia, the industrial holding company that enjoys a leading position in steel-working with production sites worldwide, recently hosted the annual meeting of the Technical Group Steel no. 5 (Finishing and Coating), of the European Commission (Research Fund for Coal and Steel), held to assess the steel industry projects being financed, mainly by means of the RFCS (formerly CECA) fund, which has been supporting innovation in the industry since 1952.
The meeting, also attended by company Chairman and CEO Antonio Marcegaglia, provided the opportunity for the presentation of the intermediate results of the ACE-PICK demonstration project, launched to industrialise and validate the world's first Alternating Current (AC) electrolytic pickling process/technology. The process was initially developed on a laboratory scale by Centro Sviluppo Materiali, the company which still owns the relevant patent, before being put into industrial operation at the Marcegaglia plant at Gazoldo degli Ippoliti with positive outcomes over a period of more than 15 months. As well as Centro Sviluppo Materiali and Marcegaglia, the active participants in the ACE-PICK project include top steel industry names ArcelorMittal Bremen, TENOVA and SCANACON, interested in particular in this new technology's possible future applications.
The AC electrolytic pickling process is a major breakthrough in the treatment lines for flat products, since it can significantly reduce - by up to 50% - the treatment times normally required with conventional processes, on both hot and cold rolled products, and makes the use of sandblasters and/or scale-breakers optional and no longer necessary, with obvious benefits for surface quality, especially for products destined for Bright Annealing. What's more, for stainless steels, the process has delivered a significant reduction in environmental impact thanks to the lower specific consumption of reagents such as hydrofluoric and nitric acids.
