CONCLUSION
TENOVA, through productive interaction with European
and Eastern steelmakers, developed an innovative
process route based on industrially proven, referenced
units. This fully integrated line can produce hot metal
with adjustable Carbon (up to 5%)and Silicon (0,2-
0,4%) content from low-grade iron ore pellets, while
producing BF-like slag that can be granulated and sold
as a byproduct.
In order to overcome the constraints inherent in the
DRI-EAF routeTENOVA leveraged its experience in
ore smelting furnaces, owned by the South African
branch of the group (Tenova PYROMET) specialized
in the design and supply of Submerged Arc Furnaces
(SAF) and Open Slag Bath Furnaces (OSBF) for the
production of ferroalloys and base metals.
The proposed solution, for the cases analyzed, will allow
a reduction of CO emissions by roughly 70% (85% if
2
using carbon-neutral electricity)and enables existing
ironmaking plants to plan a gradual reconversion during
which the operation of the downstream units (BOFs)
will remain substantially unchanged.
