Europe's most modern galvanizing line
The hot-dip galvanizing line of Salzgitter Flachstahl is dedicated to the production of high-strength and ultra-high-strength steel grades such as micro-alloyed steels, dual-phase steels, and multiphase steels with stringent requirements for reliable surface quality.
The new hot dip line is perfect for higher-strength steels. It supports enhanced formability and, therefore, more complex component geometries – all vital criteria for the materials that will be in demand as Salzgitter’s customers continue to innovate. To achieve the required product properties, Salzgitter relies entirely on SMS group technology. In addition to the design and production of the mechanical equipment and the complete electrics and automation package, the furnace and process technology were a decisive part of the SMS group scope. Several key technologies stand out in that respect:
- Drever annealing technology
- PrOBOX® technology
- Air-knife
Transparency is especially important when there are disagreements and things are not going perfectly. We made sure that everybody on the team knew it was not just ok to say when they didn’t have a solution to a problem – it was expected. We would then take the problem to the next level of management of expertise, work on it, find a solution, and feed it back to the teams, all the while keeping them moving and productive.
