Advantages
Analysis of the metal poured from the
furnace will be constant, even if the cast
iron is held within the furnace for many
hours. A perfect consistency of metal
analysis and temperature is maintained
by the harmonisation of unavoidable
variations in the cast iron coming from the
melting furnaces.
This eliminates the waste from having to
ingot, because it ensures that the iron is at
the correct temperature, right from the first
pour. Also, the tailings residue of the pouring
ladle can be recycled into the receiver furnace
rather that being poured into ingots.
It permits correction of the analysis of
the iron through the possible addition of

iron alloy and additives, while the melting
furnace maintains a feed of standard cast
iron directly through the launder. In this
way, the receiver furnace can produce special
cast irons for the production of nodular,
ductile and compacted grades of iron.
Air-cooled inductor up to 500kW
The FOMET Duplex design features an
easy and quickly interchangeable inductor,
with a patented flange mounting system
for sealing the inductor to the furnace
body. Simple and fast hot changing of the
inductor is possible (between two and four
hours) thanks to the company’s exclusive
sealing system. The high efficiency
inductor includes specially developed air

cooling of the coil for power up to 500kW.
Mixed air and cooled water circulation
is contained within a closed loop system
for higher power. Energy blackouts and
cooling interruptions, even for a matter of
hours, can be overcome without damage.
Low energy consumption (up to 30% energy
savings) is assured compared to competitive
designs. This highly customisable design,
size and configuration is adaptable to meet
every foundry’s needs.
The design uses clean energy, requires no
water consumption and creates no dust or
fume emissions, combined with minimal
operating noise, leading to a cleaner
foundry working environment.

Collaboration to optimise safety and efficiency
UK-based Asmet and Germany’s Saveway
are collaborating to optimise safety
and efficiency in foundries and melt
shops, promoting specialist monitoring
equipment in the UK for use in melting,

holding and treatment vessels.
Saveway has acquired more than 20 years’
experience in the field of safety technology.
Five advanced, patented systems give
foundries optimum safety for operators and

equipment, plus the opportunity to save on
relining and energy costs. This technology
enables operators to measure the remaining
thickness of a refractory coating within the
metal melting process and avoids metal run
outs. Moisture measurement, monitoring
of drying and pinpointing detection of
leakages are also possible with Savedry
technology. Customised solutions are
complemented by qualified after-sales service.
“This collaboration enhances our range
of services to improve metallurgical
process control and we are excited to
help customers embrace new technology
and invest in a proven, state-of-the-art
system” said Dominic Oates, Asmet
Representative.
As Saveway Sales Engineer Mario Merta
explains, Asmet is a well-established
foundry supplier throughout Europe and
in particular in the UK. “By working
closely together and making personal site
visits, we can offer customers bespoke
designed systems with the comprehensive
long-term support they require.”

Spanish dosing furnace expertise
Available from UK-based
Ramsell-Naber are dosing
furnaces manufactured by
partner organisation, Krown
of Madrid, Spain. Krown
specialises in the production of
aluminium furnaces, producing
dosing furnaces, shaft melting
furnaces, holding furnaces and
transport ladles.
Krownmatic is a holding
and dosing furnace without
crucibles. The holding
chamber is heated by SiC
resistance rod elements and
comes equipped with a multifunction electronic system
for dosing. Different models
of these airtight furnaces are

available with capacities from
450kg to 4100kg, all of which
operate under pressure. The
furnace is lined with refractory
cement that is non-wetting and
resistant to molten aluminium.
Thanks to the high quality
of refractories used and with
correct maintenance, a lining
life of more than 10 years is
possible.
Advantages of this
equipment include low power
consumption, high metal
quality, dosing precision,
close temperature control and
the ability to fill during the
production cycle.
