Galvanizing Technology Committee Activities

The GTC met 8–9 March 2018, Memphis, Tenn., USA. Nathan Wenning, GTC chair, reviewed a presentation prepared by Frank Goodwin and Joseph McDermid about AISTech 2018 and MS&T18. For MS&T, to be held on 14–18 October in Columbus, Ohio, USA, the session chairs have been arranged and one paper has been accepted so far.
Nominations were taken for GTC officers for the 2018–2019 term.
The group then reviewed the 2018 AIST North American Galvanizing Lines Roundup, which was published in the February 2018 issue of Iron & Steel Technology.
Planning commenced for the GTC’s Fall 2018 meeting. Wenning asked for suggested topics and a location. It was agreed to hold the 2018 fall meeting in the Pittsburgh area, which has both coating lines and roll manufacturers close by. The tentative date is the second week of September.
It was suggested that a call for papers be sent out to all suppliers. Perhaps this may point to another topic on which to focus.
The group then discussed various safety issues, after which the following technical presentations were given:

  • “Integrated Solution of Electromagnetic Strip Stabilization and Air Knives: First Installations, Experiences and Results,” by Matthias Black and David Heller, DUMA-Bandzink GmbH.

  • “ABB Integrated EM Strip Stabilizer With State-of-the-Art Coating Knife PosJet,” by Peter Rybing, ABB, and Jongkeun Kim, PosJet.

The next few galvanizing-related meetings across the industry were discussed, including Galvatech 2017 in Tokyo, Japan.
The past few years’ meeting topics were reviewed to identify any areas that have not been reviewed in a while.
The meeting included four presentations in the afternoon. The first two presentations were operations based, covering coating weight thickness control and fundamentals of annealing, whereas the latter two were focused on the zinc refining process as well as a zinc market review. 
The next day, Nissan Smyrna Vehicle Assembly Plant hosted the group for a tour of the facility.
