Fives Solios
A device that could be easily introduced to existing furnaces as well as
new installations.
Be able to offer a unique capability; to transfer and cast molten
aluminium from the same device.
Need a device that is safe to use and reduce the exposure of the
operators to the hot metal areas.
To be able to bring all the benefits of EMS stirring to the furnace.

›
›
Cycle reduction.
Energy efficiency.
Less operator intervention.
Metal temperature and composition homogeneity
Present benefits in terms of maintenance issues and cost
Be cost effective against conventional solutions.

PLANT DETAILS
Large secondary aluminium producer (120000t/a) based in Italy.
Casting furnace is a conventional regenerative burner fired static type.
70Tonne nominal capacity with typical bath depth of 1000mm.
Charged with predominantly molten metal from various melting furnaces.
Used to feed a dedicated belt type continuous casting machine.
Casting Machine production rate is between12 and 20 Te/hour of Si alloys.
Previous method of transfer by mechanical graphite pump.

WHY VCM CHOSE THE GENIOS
Serious issues with safety and operation using electromagnetic
pumps (50Hz) and mechanical metal moving systems previously
installed on this process line.
Attracted by “double option” capability to stir & cast with the same
unit.
Wanted better safety afforded by operating at lower frequencies
than are available with comparative EM systems.
Strong interface between bath and inductor.
Integrity of furnace not compromised by removal of inductor.
Potential operating & maintenance savings
Wanted to maintain a consistent metal quality

BENEFITS ACHIEVED AT VCM
Significant gain over safety levels experienced with the previous metal moving
systems installed on this furnace. Reduced operator intervention due to auto start &
good metal flow regulation.
Improved quality – better chemical & temperature homogeneity throughout cast
(rejects reduced by order of 15%)
Reduced dross formation (approx.10%)

Yes, achieved due to it’s side mounting and modular design.
Yes, controlled casting up to 20te/hr to the client ingot casting machine.
Improved safety due to less operator intervention – push button operation; operation stops
when the device is turned off .
›
Benefits of EMS stirring to the furnace.
›
Present benefits in terms of maintenance issues and cost.
›
Be cost effective against conventional solutions.
›
›
›
Yes, improvements in metal recovery, improved chemical & temperature homogeneity. The
Genios resulted in improved furnace efficiency due to less tasks required with the furnace door
open and improved production times.
Yes much improved life cycle compared to previous technology used, less down time with
improved operability which also offsets costs.
Yes, competitive against other EMS solutions, and requires simple modification to existing
furnaces and cast house infrastructure. Offers improved maintenance costs when compared to
metal contact devices.
