COVERFLUX
:
These fluxes are used for cleaning aluminium
and its alloys (molten form).
Due to heavy oxidation of aluminium during
melting
there is high rate of casting rejection. It
results
into metal loss also.
Coverflux dissolves this oxide and other non-
metallic impurities from the molten metal.
This flux is to protect metals from surface
oxidation
and protects metal against gas absorption
from
furnace atmosphere.
Advantages:
Reduces rejections
Increase in purity
Reduction in melting
Better yield.
DEGASSERS:
Degassers are used to remove hydrogen and non-
metallics from
molten metal to eliminate porosity in
castings.
Hydrogen pick up can deteriorate mechanical properties
and can
cause pin holes in castings. Degassers eliminates
gas porosity,
refines grains and improves mechanical
properties.
Application:
Degassing is most affective when pushed in the
metal bath in
a form of a tablet and with the help of Plunger.
GRAIN REFINERS:
Titanium and Boron based grain refiners help in
improving
Mechanical properties of the metal with the help
of increased
nucleation. They are supplied in a tablet form
and are most
suitable grain refiners to give the best refinement
required of
macro-micro structures.
DIECOAT:
Product Description:
Diecoats are generally water based lubricants
for pressure and
gravity die castings of Aluminium.
USAGE:
Diecoats form lubricating film on the dieface which
acts as a barrier
between the molten metal and dieface to avoid
erosion. Diecoat
also helps in easy stripping of castings from
the die.
Advantages:
Reduces casting stains, Reduces rejections,
Prevents excessive
die temperature.
