LONG PRODUCTS BULLETIN - SMS Meer GmbH

The new metallurgical complex will be equipped with BAT eco-technologies to meet European directives.
Rolling mill with three finishing lines. The rolling mill has three
finishing lines consisting of wire rod outlet, bar outlet with highspeed
delivery (HSD ® ) system and the patented vertical compact
coiler (VCC) for particularly compact rebar coils.
Scope of supply from SMS Meer. SMS Meer supplies a walking-hearth
furnace for a capacity of 60 t/h with cold charging and
80 t/h for hot charging, the mechanical and electrical equipment
for the rolling mill, the supply systems for hydraulics and lubricating
oil, and is also responsible for the supervision of erection
and commissioning.
Production of steel bars. The six-stand roughing mill, followed by
a cropping and chopping shear, and the eight-stand bar finishing
train both have housingless stands arranged alternately horizontally
and vertically. The finishing mill is equipped with a quick-change
platform for quick program changing.
Production of wire rod. In the wire delivery section, the shear
group and a wire rod block with ten rolling units are arranged
downstream of a water box on which sizes from 5.5 to 16 mm
can be rolled with a maximum speed of 105 m/s. Two further
water boxes, a pinch roll unit, a loop laying head, an 82 m long
loop cooling conveyor (LCC ® ), a coil forming chamber, a vertical
coil transport facility and the vertical coil compactor complete the
wire rod outlet section.
Production of rebars. For the production of rebars, the wire rod
block supplies the dimensions from 8 to 16 mm via a cooling section
at speeds of up to 36 m/s to the proven high-speed delivery
(HSD ® ) system. The larger dimensions up to 36 mm are produced
on the bar finishing mill and are also delivered to the HSD ® system
via a water cooling section. Downstream of the 66 m long cooling
bed is a cold shear, an automatic bar counter, a bundler, two wire
tying machines and the coil loading station.
VCC coiler. A further special feature is the patented VCC coiler
from SMS Meer. This proven technology produces extremely compact
coils in the size range from 8 to 16 mm at speeds of up to 35
m/s. In the first planned development stage, only one coiler will be
installed. For this, the switch behind the cooling section diverts the
products alternately either to the VCC coiler or to the HSD ® system.
The later installation of a second coiler is planned.
Layout of minimill.
The new steelworks and the
rolling mill of Slovakia Steel
Mills will be installed on an
area of 36.7 ha in the industrial
zone of Strážske, East Slovakia.
Investments amount to EUR
178 million. For the production
of high-grade structural steel
state-of-the-art technologies
are applied. Thanks to the investment,
350 jobs are directly
created for this region and
about 250 indirect jobs will be
available plus approx. 700 work
places during erection.
