Description

It is a powder flux used for removing nonmetallic
inclusions (oxide layers, carbides and others)
in pure lead and lead-based alloys, drossing off and
covering surface under melting. The dry and powdertype
dross with low metallic content was obtained after
cleaning operation by this flux. Improving the mechanical
properties of pure lead and lead-based alloys. Flux does
not react with crucible or furnace lining.

Applications

Cleaning, covering and drossing off
melt of pure lead and lead-based alloys under melting
procedure in lead scrap recycling. Cleaning pure lead and
lead-based alloys for wide range of casting techniques
and different types of furnaces.

Method of use

1. In case of lead scrap recycling covering-refining
flux introduces in melt stepwise with every part
of batch addition. The finish treatment is doing
before melt pouring. Intensive stirring of melt
promotes full reaction. After reaction the melt rest
time must be 10 minutes. The melt can be pouring
after skimming the dross.
2. In case of pure lead and lead-based alloys cleaning
for casting covering-refining flux introduces in
melt by hand foundry plunger under melt surface.
Intensive stirring of melt promotes full reaction.
After reaction the melt rest time must be 10 minutes.
The melt can be pouring after skimming the
dross.

For all applications the temperature of treatment must
be above 400°С.
