Chemical pickling lines

Chemical pickling lines for steel and stainless steel are our profession. Well-known companies worldwide have been relying on our know-how for decades.

The ideal concept for a customer-specific plant is developed through dialog with our clients while taking all the relevant parameters, plant requirements and site conditions into account. Only when all of the factors and requirements associated with each process stage have been considered as a whole can a well-thought-out solution be devised that also allows for the production environment, operation and plant technology to be further developed at a later date.

Steuler is able to supply optimized, industry-proven plants and processes for the surface treatment of a variety of materials, geometries and throughput capacities. Our focus is always on delivering high treatment quality, optimized chemical and energy consumption, low operating and capital investment costs together with minimal environmental impact.

The Surface Technology Division supplies a variety of technologies for pickling and surface treatment:

  • For wires: Tunnel and Monorail Pickling Lines
  • For pipes: Tunnel and Autoclave Pickling Lines
  • For profiles, rods and sheet metal: Roll Pickling Lines

All of these plants have one thing in common: Low energy consumption, optimized use of chemicals, minimal exhaust air volume, improved protection combined with low personnel requirements reduce both operating and capital investment costs.

High plant availability, high surface quality, high operating flexibility – Steuler Surface Technology has the ideal solution in each case.

Expandable, modular design

Steuler Equipment Engineering develops and designs "your plant" based on your specific requirements and local circumstances. In addition to surface treatment plants, Steuler also supplies the necessary environmental technology, such as exhaust gas and wastewater treatment plants, regeneration and recycling systems for spent acids, process media and wastewater, including wastewater-free designs (ZLD = Zero Liquid Discharge). We always consider a surface treatment plant in conjunction with these parameters too, as they often make decisive contributions to improving manufacturing quality while demonstrably reducing operating costs and sustainably reducing environmental impact, resulting in immediate benefits.

The following steps are involved in the chemical surface treatment process e.g. of wire rods and drawn wires:
