The range of ZINCOVER products contain fluxes which
serve two purposes of protecting and cleansing during melting and for
recovery of Zinc from drosses.
Zinc is a metal which is very prone to oxidation, resulting in a high
incidence of Zinc oxide inclusions and significant losses of metal in the
dross. Use of ZINCOVER STD ensures oxidation to a minimum, and that
non-metallic inclusions coalesce and float from the metal.
Drossing off flux
Under normal circumstances the dross from a melt of Zinc or Zinc base Alloy
has a high metal content and benefit is obtained from reducing the residues
and returning the metal to the melt in a single process in the melting unit.
This is achieved by adding ZINCOVER-85 to the dross which produces an
exothermic reaction and reacts with Zinc oxide dross releasing Zinc metal.
Sufficient ZINCOVER STD approx. 0.5% by weight is added during early stages
of melting to form a cover. When charge is completely molten add another
0.5% and rabble the melt well. Melt is allowed to settle.
For Recovery of Drosses
For maximum efficiency the dross should be allowed to cool and blacken
overall so that all flame has died out. When the melt temperature is around
480 C ZINCOVER-85 is added progressively until a powder residue is obtained
on rabbling further. Quantity of ZINCOVER-85 depends upon the quantity of
ZINCOVER compounds are hygroscoplic in nature. Containers should be
kept securely closed when products are not in use.

Saru Z-21 is a revolutionary flux and has been especially
formulated to reduce physically entrapped zinc and zinc oxide formation
substantially in hot Dip galvanizing process. SAZU Z-21 flux
melts at 194 'C (300'F) coats the liquid and then combines with the oxide
particles assuring rapid reaction. Fumes and objectional smoke are minimized
and the surface of the metal is protected from oxidation.
How Does 'Saru' Z-21 Function
As soon as 'SARU' Z-21 flux is added in the bath it gives a molten foamy
layer cover on the whole bath thereby protecting the molten metal from
atmospheric-oxygen, reduces formation of zinc ash to as low as 6-10% of
every day consumption in comparison to 12 to 16% with the conventional
method being followed.
A comparative study is given below between conventional process and with
SARU Z-21 flux process.
'SARU' Z-21 (Wonder Flux)
||Wt. of ash
||% loss on
||collected every day
This is a smokeless Galvanising Flux and is almost twice as efficient as
regular Z-21 reducing Zinc Ash formation to as low as 3-5%.
Advantages of Saru Z-21 Flux
- Reduces formation of zinc oxide and physically entrapped zinc from
12-16% to 6-8% on total zinc consumption every day.
- Helps in giving uniform zinc coating on the galvanizing objects.
- Reduces zinc dust.
- Brighter piper, tubes.
- Very convenient to use.
