Ascoval to revamp special steel caster
Danieli is going to revamp the fourstrand
caster, which it had supplied to
Ascoval Saint Saulve in 2007.
Originally designed for the production of
180 to 325 mm rounds, the caster’s product
range will now be extended to include
square billets of 150 to 240 mm and rectangular
blooms of 300 mm x 365 mm.
High-grade rail steel as well as engineering
steel grades for industrial applications will
be processed, last but not least enabled by
the Danieli Rotelec final electromagnetic
stirrers and the slow cooling system. Hot
tests are scheduled for August 2020.

Salzgitter enters field of commercial hydrogen production
Salzgitter Flachstahl GmbH (SZFG) has
awarded Siemens Gas and Power an
order to build a 2.2 MW Proton Exchange
Membrane (PEM) electrolysis plant.
The PEM plant is due to commence operation
in the 4th quarter of 2020 and cover
SZFG’s entire current demand for hydrogen.
The necessary electrical power will
be generated by seven wind turbines with
a capacity of 30 MW. These will be erected
by Avacon AG on the Salzgitter Group
site and will likewise enter service from
2020.
Salzgitter AG Executive Board Chairman
Professor Heinz Jörg Fuhrmann
commented: “We are proud to be pioneers
in the industrial application of
hydrogen in the steel industry. As our
SALCOS project has demonstrated, we
are technologically in a position to
achieve significant reductions in CO 2
with the aid of hydrogen. The Salzgitter
wind hydrogen project is an important
building block on the way towards climate-friendly
steel production. It is
now the turn of politicians to put in
place the right conditions to support
the transformation into a low-CO 2
industry.”
Hydrogen has long played a role in
steelmaking, particularly in enhancing the
quality of annealing processes. The gas
is currently supplied by Linde AG, and
this company will in future continue to
safeguard Salzgitter’s own production. A
containerized plant will be erected in
Salzgitter which at full capacity will produce
400 Nm³ of hydrogen. PEM technology
is ideally suited to exploiting the volatile
generation of wind and solar power.
The highly dynamic mode of operation
allows the plants to respond to demands
resulting from the rapidly fluctuating power
supply.

Acciaierie Venete installs bar finishing equipment
Acciaierie Venete has commissioned the
Danieli Drawer 550 finishing line for SBQ
bars.
The new Danieli finishing line is
designed for the production of 18 to
82.5 mm diameter rounds and squares
from 30 to 60 mm. Covered by Danieli
patents, the Drawer technology allows
the production of ready-to-use, hotrolled
bars with tight dimensional tolerances
of 1/8 DIN. Round bars can be
produced by normalized rolling and thermomechanical
rolling. The finishing line
consists of four rolling components:
units Nos. 1 and 2 are equipped with
two and units Nos. 3 and 4 with four
rolling rings each.
Danieli has implemented free-size rolling
technology, i.e. a family of finished
product diameters can be produced from
one entry feedstock section with one set

of Drawer rolling units. Rolled stock dimensions
and surface qualities are monitored
by Danieli Automation Hi-Profile gauges
installed at the Drawer entry and exit
sides. The Q-Shape automation package
controls the operating parameters in a
closed loop, ensuring that the finished
product dimensions are within the requested
tolerance.
