Zinc

Zinc is committed to a sustainable approach for our various zinc products: dust, oxide, metal and fines. We produce zinc dust from highgrade and special highgrade (SHG) zinc metal, as well as from zinc secondaries. To produce Type I zinc dust, we rely on bottom dross as a primary source of raw feed.

Sep 01, 2010· Electrogalvanizing Production Process. Soluble anodes of pure zinc are also used. In this process, the steel sheet is the cathode. The coating develops as zinc ions in the solution are electrically reduced to zinc metal and deposited on the cathode. Grain refiners may be added to help produce a smooth, tightknit zinc coating on the steel.

zinc coating. Zinc coating development depends primarily upon steel chemistry. All other controls are secondary or tertiary controls in the process. Q: Does galvanizing change the mechanical properties of the steel? A: In a nutshell, No. The mechanical properties of steels typically galvanized are not affected by any step in the galvanizing process. However,
