Annual capacity: 690,000 t of wire rod
Wire rod mill with FRS ® equipment
for ArcelorMittal Hochfeld
New order
LCC ® Loop Cooling Conveyor.
ArcelorMittal Hochfeld GmbH,
with head office in Duisburg,
Germany, has placed an order
with SMS Meer for the
supply of a high-capacity
wire rod mill with FRS ® equipment
for high-grade steels.
The annual capacity will be
690,000 t of which the major
portion will be wire rod products
of cold-heading steel
grades. The mill boasts great
compactness and high efficiency
and will go into production
in August 2010.
Scope of supply. The SMS Meer order
scope comprises a walking-beam furnace,
the mechanical and electrical equipment of
the rolling mill, all of the utility systems, the
finishing facilities for the wire rod coils, the
entire rolling and cooling equipment, and
erection.
Cooling and equalizing section in loop arrangement.
Furnace, roughing and intermediate trains. The walking-beam
furnace for 155-mm square billets has a capacity of 120 t/h. It is followed
by a four-stand roughing train comprising HL (housingless)
stands with free runout and an intermediate train consisting of 14
CL (cantilever) stands, each in horizontal and vertical arrangement.
Wire rod outlet and FRS ® block. The wire rod outlet comprises
a cooling and equalizing section in loop arrangement, a wire rod
block with six rolling units and an FRS ® block (Flexible Reduction
and Sizing) with four rolling units, both in UHD design (ultraheavy
duty).
Forced and retarded cooling. The wire rod block and the FRS ®
block are each followed by a water cooling line. The heart of the
mill is the FRS ® block together with the proven cooling and equalizing
section. In addition, our scope includes the 104-m-long
LCC ® (Loop Cooling Conveyor) for forced and retarded cooling, a
total of three water cooling lines and the CCT ® system (Controlled
Cooling Technology) developed by SMS Meer.
Ultra-fine microstructures through thermomechanical
rolling. These facilities will allow ArcelorMittal Hochfeld to produce
wire rod of the entire dimensional range of 5.5 to 25.0 mm
by means of temperature-controlled rolling. Ultra-fine micro structures
can be achieved especially for cold-heading grades by thermomechanical
rolling. The maximum rolling speed for 5.5-mmdiameter
wire rod is 120 m/s.
