In the continuous sheet galvanizing process, the flux can be applied as a “preflux”, that is, applied from a water-based solution that contains the dissolved flux chemicals, or it can be applied as a “top flux”, that is, a molten salt flux layer floating on top of the galvanizing bath. In some cases, both types of flux application are used. Again, the flux is a chemical that reacts with iron oxide to remove it and leave behind a very clean oxide-free surface for rapid wetting as the sheet enters into the molten galvanizing metals.
The flux-galvanizing process serves as an alternate process for the continuous galvanizing of steel sheet. Although it has its own unique processing problems, such as the formation of flux fumes and flux ashes that need to be handled as waste products.
We, AMBICA Chemical has developed HODGA LIQUID FLUX which sustain with continuous galvanizing sheet line and plays a very effective role in the savings in aspects of lesser consumption, reduce fumes and byproduct generation and provide active and adherent surface to steel for galvanizing.
HODGA LIQUID FLUX contains inorganic chemical “zinc ammonium chloride”. The weight ratios of zinc chloride to ammonium chloride can be adjusted to meet individual customer needs. Typically, these solutions also contain special proprietary wetting agents, anti-foaming agents, and possibly other viscosity-adjusting additives. It is most suitable for all types of galvanizing as well as continuous sheet, wire, and tube galvanizing operations.
