Separation and Recovery of Zinc from Hot Dip Galvanizing Dross by Immersion into Lead Bath.

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.

Exploring Carbide-Free Bainitic Structures for Hot Dip Galvanizing Products

Electrochemical Recovery of the Zinc Present in the Spent Pickling Baths Coming from the Hot Dip Galvanizing Industry by Means of the Use of Two Different Membranes

EXTENDED ABSTRACT Spent pickling baths coming from the hot dip galvanizing process represents an environmental problem due to high ZnCl2, FeCl2 and HCl (among other substances) concentrations. This problem, together with the decrease of natural reserves of nonferrous metals, makes zinc electrowinning coming from spent pickling solutions an interesting alternative. Moreover, membranes, or other ...

Effect of Aluminum on Microstructure and Thickness of Galvanized Layers on Low Carbon silicon-Free Steel

In hot dip galvanizing, several parameters such as chemical composition of coating bath, immersion time and surface roughness of specimens could affect microstructure and properties of coating. In this article, the effect of aluminum content, immersion time and surface roughness on structure and properties of alloy layers have been investigated. Specimens of low carbon silicon-free steel with d...

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...
