UniMet Company has developed the revolutionary
technology that provides increase of large rectangular
aluminium ingots (slabs) quality by means of
crystallization process control in the liquid heart
especially while casting alloys 2xxx, 5xxx, 7xxx series for
airspace and automotive industries.
Aluminium ingot liquid heart MHD stirring (LHMS) is
based on running electromagnetic field, created by a
couple of stirrers from both sides of the ingot. They
provide control of heat and mass transfer by stirring the
liquid heart during the process of casting. This allows
solving all tasks arising during the process of value added
products manufacturing. This includes homogenizing of
chemical and structural composition along the whole
ingot volume with a dramatic defects reduction. Main
peculiarity of the electromagnetic stirrer technology
developed by UniMet is settings flexibility depending on
the type of alloy, relatively low energy consumption,
compact size, easiness of installation.
LHMS stirrers are installed within the existing casting pit
volume from both sides of the ingot. Inductors
installation does not require redesign of existing casting
machine or mould, and requires only installation of a
support frame over the shaft, which allows fixing the
inductors and adjust their position. LHMS stirrers can be
installed at multi strand casting pits, while one inductor
can influence on two ingots simultaneously.
Ingot cycle time reduction up to 25%;
Defect products volume reduction up to 30-40%;
Chemical composition improvement along the whole
ingot cross section;
Control over the heat and mass transfer within ingot
liquid heart;
New alloys manufacturing possibility;
Structural composition improvement along the whole
ingot cross section;
Economical effect could be up to 3 mln. USD/year per
one mould casting pit.

2. LIQUID HEART METAL STIRRER FOR LARGE INGOTS
A distinctive feature of electromagnetic stirring
technology, developed by UniMet, is the flexibility of
options depending on the type of alloy, relatively low
energy consumption, small size, easy installation.
The calculation presented in the table below was done
based on one mould casting pit with capacity of 30 000
ton/year, mould size 1,5 x 0,6 m, casting speed – 60
mm/min, 7xxx alloys series, rejection - 4%. It is necessary
to take into account that calculation is done for the
casting pit with one mould. During simultaneous casting
of several ingots at a time the economical benefit with
the LHMS technology implementation will be higher.
