X-Pact® Pickling Model for Stainless Steel


  • Under consideration of all production-relevant parameter, obtain a high production quality and increase yield, while saving acid and steam


  • Model-based calculation of acid and metal concentrations
  • Continuous small acid dosing instead of batch feeding at the beginning of a campaign
  • Temperature compensation to counterbalance concentration fluctuations

Technical advantages

  • Stable acid concentration
  • Low acid concentrations possible because they do not fall below their minimum
  • Reduced acid consumption
  • Reduced amount of spent acid


  • Optimal strip surface quality due to stable pickling conditions


  • Lower acid consumption
  • Less spent acid
  • Reduced number of chemical analyses of the pickling bath
