LONG PRODUCTS BULLETIN - SMS Meer GmbH

The new wire rod mill has been designed
to roll technically demanding grades,
which are therefore of extremely high
quality, to the closest tolerances. This line
is characterized by compactness and efficiency
and achieves an annual capacity of
690,000 t.
Furnace, roughing
and intermediate train
The walking-beam furnace for the heating
of billets measuring 155 mm square will
have an output rate of 120 t/h. This is followed
by a four-stand roughing train comprising
HL (HousingLess) stands with
downstream free runout and an intermediate
train consisting of 14 CL (CantiLever)
stands, each in horizontal and vertical
arrangement.
Equalizing section
in loop arrangement
The core element of the mill begins with
the cooling and equalizing section in loop
arrangement. Owing to this arrangement,
an optimal run-in temperature for each
steel grade can be preset in front of the
wire rod blocks.
Wire rod blocks with innovative
MEERdrive® technology
The wire rod finishing block with six rolling
units and the FRS® block with four units
(Flexible Reduction and Sizing) – both in
UHD (Ultra-Heavy Duty) arrangement – are
provided with our innovative individual
MEERdrive® technology offering numerous
benefits. The most important ones are:
n total flexibility in roll pass designing
n essentially simplified rolling ring
management
n reduced operational costs
High-speed loop laying head.
MEERdrive® technology in
the wire rod finishing block
with six rolling units.
Cooling lines for high-quality
finished products
With the water cooling lines downstream
of the wire rod block and the FRS® block as
well as the 104-m-long LCC® (Loop Cooling
Conveyor) for intensive and retarded cooling,
all the requirements for the production
of high-quality finished products are
fulfilled. Furthermore, the required cooling
strategies based on the CCT® model (Controlled
Cooling Technology) developed by
SMS Meer can be simulated, and then adjusted
and controlled online during operation.
The entire coil handling equipment
designed to be particularly protective to
the finished material is also adapted to the
high-quality finished products.
