GAL FLOW STI

Our R & D Department has developed a novel METALLIC FLUX COMPOUND to givebright finish to the galvanized steel & to increase the fluidity of molten Zinc. Theaddition of this compound can replace Aluminium, Zn-Al alloy addition to the moltenzinc. It also reduces the Zinc ash & controls the coating.

Gal Flow STI will reduce ash formation by as much as 20% in general galvanizingplants & structural galvanizing plants.

This compound melts & liberates the metal leaving residues. In Batch galvanizingprocess, this compound is to be added to the molten zinc bath at the beginning of the

shift or during recess time / idle time. The frequency of addition is every 4 hours. The

quantity to be added is about 1.5kgs to 2.5kgs every 4 hours depending on the

production / surface area of Zinc bath. For a surface area of 10Mt X 1.5 Mt, 2kgs of

Gal Flow STI will be sufficient for 4 Hours.

Procedure for Addition of GAL FLOW STI:

Take approximately 2kgs of Gal Flow STI. Skim the Zinc ash in the bath & add this

compound all over the bath. After about 10 to 15 mins remove the oxide layer in the

bath with a skimming blade. Gal Flow STI melts & forms a minute layer on the molten

zinc reducing the ash formation. It also reduces the surface tension of the molten zinc

giving it better fluidity thus controlling the coating.

Advantages in a Nutshell:

1. It increases the fluidity of Zinc thus reducing the coating & improves uniformity.

2. It forms a minute layer over molten zinc thus reducing the ash formation.

3. It increases the surface finish/appearance of galvanized steel.

4. It will replace the Aluminium alloy addition/ Zn-Al alloy addition to the bath.

5. It reduces the ash formation by 20 %.

6. Optimum use of Zinc.
