Valin Xiangtan starts up bloom caster
Valin Xiangtan has successfully started
up its new, five-strand bloom caster, less
than 13 months from the contract signing
with Danieli.
The caster operates with different withdrawal
units along the line performing
simultaneous soft and hard reduction, to
further optimize internal quality, particularly
with high-carbon grades which tend to
exhibit higher porosity and segregation.
Immediately after the start-up the caster
successfully produced a wide range of
steel grades, including high-alloyed and
high-carbon spring steels in square and
rectangular sections, 280 mm x 280 mm
and 350 mm x 430 mm.

Waelzholz New Material builds new cold rolling mill
Danieli Fröhling is building a new 4-high
cold rolling mill for Waelzholz New
Material in Taicang, Jiangsu province.
The new cold reversing mill is designed to
roll a wide product mix of special steel
grades, from an entry thickness of more
than 5 mm down to a finish thickness of
below 1 mm at a maximum strip width of
670 mm. The mill can also be operated in
skin-pass mode. It will be equipped with
independently driven, twin-drive work
rolls, and high-torque drive spindles.
Danieli Automation will supply the electrical
and automation systems. An intelligent
data analysis system, ready for Industry 4.0,
will be connected to the Wälzholz proprietary
process data management system.
Danieli is responsible for the supply of the
complete equipment on a turn-key basis,
from design and manufacturing up to and
including all erection and commissioning
activities. The project is lead by Danieli Fröhling,
in close collaboration with the Wälzholz
headquarters in Germany. The cooperation
is planned to be extended beyond the final
plant acceptance, aiming at long-term process
enhancement support and service.
