Tunnel Pickling Plants

Steuler offers tunnel pickling lines for wire rods, tubes, plates, bars, profiles and construction parts in a bath batch process, covered by a tunnel to eliminate the escape of corrosive fumes and protect the operators, for medium and high throughputs.

Through the cascade bath system, the necessary treatment medium and time can be optimized for each type of material grades and types to avoid high quality surfaces by less chemical and fresh water consumption. A crane system transported the material automatically PLC- controlled on base of the necessary treatment steps through the different treatment bathes

A crane system transportes the material automatically PLC- controlled on base of the necessary treatment steps through the different treatment bathes.

The main benefits are:

  • less operator costs
  • protection of the operators against the treatment solutions
  • optimized chemical consumption
  • high availability and high surface quality
  • low fresh water consumption, less fumes flow rate
  • automatic system with practical unlimited treatment programs
  • easy extension for higher capacity or
  • other materials
