Macrovibe
dry vibratables are dust-free for a cleaner work and healthier
environment during installation. When used as a parting layer between working lining and safety lining brick, Macrovibe resists metal penetration, protecting the safety lining, and makes tearout of the working lining easier. Macrovibe is also used as a bottom-levelling layer for steelmaking ladles and furnaces and as a bedding material for blast furnace runner troughs. Because Macrovibe falls cleanly away from the safety lining, there is no need to hammer at the safety lining to remove stuck-on steel or refractory. |

MACROVIBE when used in Electric Arc Furnaces:
 |
- Cooler
furnace shells
- Tighter
brick hotface to coldface
- More
heat kept in the steel
- Stops
penetrated steel from reaching the shell
- Provides an expansion allowance for brick
MACROVIBE
50MF - 50% Alumina, most insulating, will not hydrate
MACROVIBE 85MF - 85% Alumina, insulating, will not
hydrate
MACROVIBE M92 - 92% Magnesia, insulating, will stop
penetrated steel and slag
Packaging:
Macrovibe is supplied in paper bags or supersacks.

Because
many of our Macrovibe products can be handled in bulk as
well as by hand, Imacro offers
an mechanical feeder system
to assist installation or application of our products. Several
feeders are
operating in the United States and Canada for
installing Macrovibe behind the working lining of steelmaking
ladles.
The system allows product to be handled in 2000 to 3500
lb supersacks instead of smaller bags. An auger
takes the
product to a gravity-feed hose which delivers product directly
to point of installation, increasing
efficiency and reducing
the strain of lifting and manipulating bags.
Feeder systems are custom designed for each customer's plant layout and needs.

Macrospray
products are water-based alumina particle suspensions which,
when sprayed onto steel or
refractory surfaces, assist in
the dumping out of skulls or cleaning-off of buildup. The
suspension is stable for a period
of weeks and may be pumped
with a variety of systems and sprayed with a simple orifice
nozzle;
Imacro can supply an air-operated diaphragm pump
for the purpose.
Macrospray is used as a refractory parting material for
slag, steel and non-ferrous metals.
Y101 |
Used
for: furnace slag pots, runner troughs, slag trays
at caster, refiner roof where splashup occurs, anode
casting conveyors in non-ferrous operations. |
Packaging is in drums on pallets or reusable totes |
|
Y101
and S204 are available in dry versions, to be mixed
on-site with water. Each is designed for a different type of mixing. |
|
Packaging for 18 kg paper bags or 1000 kg supersacs |

insulating powders, reagents, slag tracers. |
Caspar |
Blends
high-cal lime and fluorspar in any ratio, for fluidizing
ladle slag and increasing slag sulphur capacity while
reducing the risk to slagline refractories of direct
addition of fluorspar alone. The most popular mixes
range from 40% to 70% lime. |
T/L |
Aluminosilicate
thermal insulator is very free-flowing, self-spreading
across the surface of molten steel on tundishes or
ladles. |
500
i |
A
basic powder designed for casting tundishes where a
fast initial melt down is required at the steel interface,
together with a pronounced insulating effect on top. |
A
variety of other synthetic slag compostions are available
to suit individual customer requirements. |

Packaging:
Macrocover products
are packaged in plastic bags in pallet boxes
or in sacks.

Custom Design of Slags and Fluxes
Many
customers have specific needs and demands for tundish cover
slags, often because of the demands
for steel quality. Imacro
will work with customers who have specific needs for slags
or fluxes in order to
provide them with custom solutions.
These can include slags or powders with:
- rapid liquid development to seal the steel surface against reoxidation
- moderate to high alumina capacity to trap inclusions,
- low
levels of specific components to avoid pickup in tight-spec
steels
(such as carbon, hydrogen or nitrogen) - self-spreading across steel surface when applied
- high insulating capability to retain steel temperature
- avoid crusting or resolidification on tundish surface
- low attack on slagline refractories
- Controlled slag fluidity to promote chemical interaction with molten steel
- MACROMAG 82, 88 and 92 are supplied as artificial ladle slags

The
Macroram line includes dolomite and magnesite and alumina
ramming mixes.
Ramming mixes are supplied in 50 lb sealed
bags.
Dolomitic
- magnesite mixes are chemically compatible with dolomite
lined steel ladles and are rammed
into annular gaps around
plug ladle bottoms, as well as around well and plug blocks.
They are designed
not to clump up in the bag in transit,
and will remain free flowing when the bag is ripped open,
yet ram into
a hard dense monolith. When alumina brick linings
are used, AP 85 is recommended. Imacro offers
ramming versions of 50% and 69% magnesia as
well as 85% alumina. Shelf life is 3 months and longer.
Packaging:
Ramming mixes - 40 or 50 lb plastic bags in palletainers
of 3000 - 3500 lb.

Other refractories including ladle patching, castable and others have been created for specific customer requirements.

LINK: 
| Microtherm is a highly efficient insulating material, used
widely in steel, cement, nonferrous and glass industries, as well as in appliances, flight recorders and aircraft engine insulation. Where space is an issue or maximum insulating efficiency is needed, Microtherm is the best choice. It comes in several forms: panels, flexible panels, block and pipe sections, or it may be custom-made into formed shapes for specific applications. |
