Turbulence pickling

The specially designed turbulence pickling tank is characterized by a low volume of acid. Sludge deposits are minimized by the use of spraying lances in the entry, exit and side sections and by a patented tank bottom design. The patented immersion cover forms the top surface of the pickling channel and thus ensures efficient sealing of the pickling tank. This results in lower evaporation losses, which in turn enables considerable savings due to the reduced consumption of energy and acid.

Electrolytic pickling

The electrolytic pickling section is characterized by the efficient utilization of energy due to the high electrolyte flow velocity and the proven design with separated electrodes. High operating efficiency is thus guaranteed since only small losses occur between cathode and anode, which results in 10 % lower energy consumption. Spraying lances in the entry and exit sections and further nozzles in the side section enable high circulation of the

Pickling and dosing model

This solution continuously adapts the acid concentration in the pickling tanks to match the material. Simultaneously, a pickling and dosing model ensures a consistent pickling quality and cuts acid consumption. To shrink energy consumption, the model is coupled with the furnace control.
