REACTION KINETICS OF THE FORMATION OF INTERMETALLIC Fe – Zn DURING HOT - DIP GALVANIZING OF STEEL

P. Pokorny, J. Kolisko, L. Balik – Czech Technical University – Klokner Institute, Prague, Czech Republic P. Novak – Institute of Chemical Technology, Prague, Czech Republic This review article mainly describes the composition of intermetallic Fe Zn, i.e. zeta (ζ), delta (δ1k + δ1p), gamma1 (Γ1) and gamma (Γ) on galvanized steel during low temperature galvanization (t ~ 450 °C). It gives detail...

Exploring Carbide-Free Bainitic Structures for Hot Dip Galvanizing Products

Some Applications of Neural Networks for Condition Monitoring in Industrial Systems for Hot Dip Zinc Galvanizing

The paper describes the abilities of some particular neural network structures (NNS) to provide condition monitoring in a real industrial system, designated for hot dip zinc galvanizing. Condition assessment of a molten zinc bath furnace, and more specifically analysis and prediction of the technical condition in galvanizing kettle walls are also developed in this paper.

Treatment of spent pickling baths coming from hot dip galvanizing by means of an electrochemical membrane reactor

The performance of a one (OCR) and a two-compartment electrochemical reactor in the presence of a cation-exchange membrane (CEM) for the zinc recovery present in the spent pickling baths is analyzed in this paper under galvanostatic control. These solutions, which mainly contain ZnCl2 and FeCl2 in aqueous HCl media, come from the hot dip galvanizing industry. The effect of the applied current, ...

Effect of Mg on the Microstructure and Corrosion Resistance of the Continuously Hot-Dip Galvanizing Zn-Mg Coating

The microstructure of continuously hot-dip galvanizing Zn-Mg coating was investigated in order to obtain the mechanism of the effects of Mg on the corrosion resistance. In this paper, the vertical section of the Zn-0.20 wt % Al-Mg ternary phase diagram near the Al-low corner was calculated. The results indicates that the phase composition of the Zn-0.20 wt % Al-Mg ternary phase diagram near the...
