Turbulence pickling technology

Most efficient descaling without overpickling

Outstanding features of the turbulence pickling system are a high kinetic energy, the flat pickling channel, immersion cover and hydrodynamic seals to separate the cascades. 

Racks of nozzles are constantly spraying heated hydrochloric acid into the shallow pickling channel and generate an extremely high turbulence. This ensures maximum contact between the acid and the strip surface by continually forcing fresh acid into the cracks in the  scale layer. It only takes a short time to create the required electrochemical potential which results in fast and efficient pickling. The patented immersion cover above the pickling channel closes off the acid bath surface, minimizing evaporation losses by 30 % and the heat losses by 70 %. Furthermore, the exhaust system requires a smaller volume, which again reduces losses.
