Saru Zincover - Saru Z-21 Flux, Saru Diecoat, Drossing Off Flux and Protecting Fluxes

The range of ZINCOVER products contain fluxes which serve two purposes of protecting and cleansing during melting and for recovery of Zinc from drosses.

Protecting Fluxes
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.

Product Application
For Covering
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 dross treated.

Precaution
ZINCOVER compounds are hygroscoplic in nature. Containers should be kept securely closed when products are not in use.

Standard Packing : 20 kg HDPE jars.

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.

Bath	Method	Zinc consumption	Wt. of ash	% loss on
capacity	employed	every day	collected every day	zinc consumed
60 tonnes	conventional	6 tonnes	960 kgs.	16%
60 tonnes	'SARU'	6 tonnes	480 kgs.	8.00%
	Z-21 'FLUX'

'SARU' Z-21 (Wonder Flux)
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.
