New order
Annual capacity of 450,000 t
Daehan Steel, South Korea:
Rebar mill with
VCC® ordered
The South Korean steel producer Daehan Steel has commissioned
SMS Meer to supply a rebar mill with a VCC® installation
(Vertical Compact Coiler) for compact coils. The mill with
an annual capacity of 450,000 t will be the first rolling mill
worldwide which concentrates exclusively on the production
of compact coils. The plant is scheduled to go on stream in
April 2011.
SMS Meer supplies the key equipment for the rebar mill which includes
six housingless mill stands each in H/V arrangement for the
roughing and intermediate trains, a finishing block with eight
rolling units in V arrangement, facilities for the heat treatment, the
VCC® installation as well as the electrics and the automation. In addition
to this, SMS Meer is responsible for the coordination of erection
and commissioning.
The production line processes square billets with an edge length
of 130 mm. It is planned to expand the mill for the processing of
billets 150 mm x 150 mm in size. The rebar dimensions comply
with D10 to D16 (according to Korean standard) and the production
of the corresponding round bars is also possible.
For hot coiling, the VCC® installation is presently regarded as stateof-the-art
procedure. The VCC® technology is also ideally suited for
older mills with wire rod blocks and loop laying heads since it is
possible to produce compact and stable coils.
The Vertical Compact Coiler (VCC®) from SMS Meer is able to coil
the bars directly in vertical position. Owing to this technology, the
customers can do without turning manipulators in the future. The
throughput time is considerably reduced by the VCC® system since
the coils are already formed in their natural final position.

ICSR in Hassia, Syria:
Bar mill put
into operation
The International Company for Steel Rolling (ICSR) in Hassia,
Syria, has successfully taken the bar mill supplied by SMS
Meer into operation. On this plant, surface heat-treated reinforcing
bars are produced with speeds of up to 36 m/s in the
exit section. The mill is designed for reinforcing steel with low
and medium carbon content. The annual capacity is 300,000 t
of round bars with diameters from 8 to 40 mm.
Structure of rolling line. The pusher-type furnace for the heating
of square billets supplies a one-strand continuous rolling line comprising
roughing, intermediate and finishing trains. The roughing
train consists of six stands and the intermediate train operates with
multiple-pass mill stands in HL design and H/V arrangement. The
finishing block in V arrangement is equipped with eight rolling
units and two more units can be retrofitted. In this way, the customer
has the option to reconstruct the plant into a combined bar
and wire rod mill at a later date.
Cooling bed with HSD® system. On the entry side of the cooling
bed a high-speed delivery system HSD® (High-Speed Delivery) has
been installed. The system is equipped with a double rotating
launder transporting the straight bars to the cooling bed with
speeds of up to 36 m/s.
The scope of supply. SMS Meer supplied the complete rolling mill
including electrics and automation. The supply package included
also the supervision of erection and commissioning. In addition
to this, the scope of supply comprised a fully automated bundling
plant and a tying station.
