AFCIRON
is a range of an Iron Oxide used as a Hot Additive to be added to Cores
and Moulds in Oil, Shell, Cold box etc. type of process to improve hot
strength. Generally 0.5 % to 0.7 % is sufficient for excellent hot strength.
AFCIHOLD is a Slag-Holding compound is added as a slag coagulant
in continuos induction furnace and in molten metal pouring ladles, prior
to pouring in the mould. It may be added either to the surface of the
bath after the ladles is filled or to the bottom of the ladle after
a heel of molten metal has been poured. In application, AFCIHOLD
will expand when it comes into contact with melt, forming a lightweight,
viscous cellular mass. This mass attracts all individual slag particles
in the metal, cleans the metal by coagulating impurities, floating them
up to the slag layer and also re-entry of the impurities into the metal.
AFCIHOLD also helps in reducing Sulphur and Phosphorus compounds in
the melt.
|
|
| |
- The quantity
of AFCIHOLD Depends on the viscosity and coagulative nature of the
melt. However 1 to 2 kgs per ton of melt in ladle furnace is recommended.
Large quantities can be used for additional benefits of Sulphur and
Phosphorus reduction.
AFCIBOND is used in High Pressure moulding line as well as Air Impulse
moulding line. Procedure for AFCIBOND usage is as follows :
- Put the dry
sand in the muller.
- Add 3% to 6%
of AFCIBOND by the weight of sand in muller and mix it well for about
one minute.
- Then add other
additives like AFCICOAL powder etc and mix well.
- Add the required
amount of water as per compactibility and mix the above mixture for
6 to 10 minutes to achieve good Compression Strength.
AFCICARB is a range
Coconut Shell charcoal for Carbon Pick-Up in S.G. Iron that improves
the quality of metal & structural property. It is crushed to various
sizes as per requirement. It may be added either to the bottom of ladle
before filling with molten metal or to the surface of the bath after
the ladles is filled or to the bottom of the ladle after a heel of molten
metal has been poured. Also it may be added directly in the furnace.
The quantity of AFCICARB to be used is generally 0.5 % to 2.0 % but
depends on the extent of carbon to be picked up.
AFCIDISULF is a range of a desulphurizing agent for S.G. Iron castings
added for the disulphurization of molten metal that reduces the Sulphur
content, & increases the fluidity. Magnesium is added in S.G.Iron casting
that imparts spheroidal structure, since Magnesium has high affinity
for sulphur forming fluid slag. Hence therefore it is very necessary
to remove sulphur by using AFCIDISULF.
It may be added either to the bottom of ladle before filling with molten
metal or to the surface of the bath after the ladles is filled or to
the bottom of the ladle after a heel of molten metal has been poured.
The quantity of AFCIDISULF to be used is generally0.2 % to 2.0 % but
depends on the extent of sulphur to be removed and the temperature of
the melt. Higher the temperature, reaction is more fast and efficient.
The churning action of the falling stream and the agitation of the molten
metal ensures the intimate contact with AFCIDISULF.
AFCIDEOX is a range of a Deoxidizing agent for Cast Iron castings that
deoxidizes and removes the unwanted gases from the molten metal & improves
the quality of metal obtained. It is added in continuous induction furnace
and in molten metal pouring ladles, prior to pouring in the mould that
cleanses the molten metal by removing oxides and other inclusions.
AFCICULANT is a range of an inoculants for efficient ladle inoculation
of Cast Iron available in various grades suitable for different types
of Castings based on metal composition, section thickness, melting temperature
grades of Cast Iron, ladle size, and fade resistance requirement etc.
Effectiveness of inoculated Iron for its desired purpose is tested by
chill/ wedge test from which the degree of chill can be decided and
accordingly inoculation process can be carried out. AFCICULANT is to
be added to flowing stream of clean molten metal from furnace to ladle
slowly and as late as possible. It should be added accurately, since
over inoculation or under inoculation might cause problems like shrinkage,
porosity, low strength and machining property. Generally 0.2% to 0.4%
of the melt in ladle to be added. .

| PRODUCT FEATURES |
| AFCIRON : |
- It imparts exceptionally high and uniform Hot Strength
- It gives strong cores/ moulds and good storage stability without
surface deterioration.
- It develops uniform build-up with very low gas evolution. · Better
knock out property and easier machinability.
- It provides good casting surface finish, hence economical due to
reduced fettling and cleaning costs.
|
| |
| AFCIHOLD : |
- It ensures a
clean metal surface free from Slag by co-agulating the impurities.
- It forms an Intumescent-Insulating
layer on the top of ladle which significantly reduces the radiant
loss of heat that may be maintained until pouring time and hence therefore
acts as an insulating barrier.
- It also reduces
Sulphur content and also prevents reentry into the bath when added
to ladle by holding them in the slag.
- It does not produce
objectionable smoke or noxious fumes, hence non-polluting.
|
| |
| AFCIBOND
: |
- It is a superior
quality Sodium based Bentonite.
- It gives an
exceptionally high Green and Dry strength.
- It imparts excellent
flowability with optimum tempering water.
- High thermal
stability & lower rejects, develops high cohesive strength, & maintains
mould strength in pressure casting.
- It gives sharp,
strong mould edges & corners.
|
| |
| AFCICARB
: |
- It is used for
Carbon Pick-up in S.G.Iron castings to overcome the problem of Carbon
deficient metal scrap.
- It is also used
as a replacement for Petroleum Coke.
- Yield obtained
is about 70-80 % hence increases quality production of castings.
|
|
| AFCIDISULF
: |
- It reduces the
Sulphur content of the molten metal efficiently and economically.
- It increases
the fluidity of melt.
- It maximizes
the recovery of magnesium required for the structural property of
S.G.Iron.
|
| |
| AFCIDEOX
: |

misrunning of melt and mechanical properties of the metal is considerably
improved.
- It gives strong
and pressure tight castings.
|
| |
| AFCICULANT
: |
- It results in
