Description
This paper gives an overview of transition from H2S gas wiping to nitrogen wiping and the eventual installation of a zinc coating monitoring and control system. It discusses the improvements and advantages realized after installation and presents graphs indicating the level of control that was achieved. Experiences gained in the production of Galfan coated wire and “mid-range” zinc coatings are discussed. It also discusses experience gained in the production of high-carbon zinc-coated products utilizing the same technology.
