      Challenges in Galvanizing Advanced High Strength Steels (GI, GA,…)
      Oral Presentation
      Galvanizing lines often apply pre-oxidation and reduction in their annealing cycle to ensure successful galvanizing of Advanced High Strength Steels with good coating appearance and excellent adhesion. Tata Steel uses flash pre-oxidation by means of an oxygen bar, by which an oxygen-rich gas mixture is blown onto the steel strip. The thickness of the Fe-oxide layer formed during the...

      New Technological Concepts
      Oral Presentation
      Today, steel producers find in their portfolio many kind of steels, including the new high strength steels, each with their specific heat cycle. Adding to this the final customer specifications, and on the top of it the requirements of various sizes, the coil schedule faced day-by-day on production level stretches into an extensive mix. A modern galvanizing line must be a flexible tool able to...
