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...

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.

Optimization of exposure time for hot dip galvanizing and study the effects of preflux bath additives on the microstructures of galvanized steel

The objective of this research work is to optimize the time of exposure for hot dip galvanizing of mild steel, so as to achieve such a microstructure of zinc coating that protects mild steel for long against atmospheric corrosion. In order to decide the above mentioned parameter the polished samples, one at a time, were dipped in to 500 g molten zinc at 460 to 470 oC in the crucible for a diffe...

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...
