Orders for
cold rolling
mills
NORTHEAST Light Alloy Co, Ltd (NELA),
China, has ordered a new CVC® plus
aluminium cold rolling mill in six-high design
from SMS Siemag. With the new aluminium
cold rolling mill, NELA is entering modern
production of high-quality aluminium strip
products. In addition to various finished
products, input stock for foil manufacture will
be rolled on the CVC plus six-high stand.
The new SMS Siemag cold rolling
mill, which will constitute the central
production unit of the works in Harbin,
is designed for a capacity of 85,000tpy
and processes incoming strips with entry
gauges of maximum 8mm and widths of up
to 1,900mm. The minimum final gauge is
100μm, and the maximum coil weight 21t.
The six-high stand is equipped with
CVC plus intermediate-roll shifting and with
multizone roll cooling for influencing strip
flatness. A Hot Edge Spray system (HES)
is provided to influence strip flatness in
the strip edge area. The Dry Strip system
(DS) installed in the exit section of the mill
ensures that the residual oil on the surface
of the rolled strips is kept to a minimum.
A coil preparation station, a coil conveyor
system and the full range of utility systems
complete the mill stand.
SMS Siemag has also received an
order from Novelis do Brasil Ltda, Brazil,
to supply a new two-stand cold rolling
mill for aluminium alloys. The two-stand
tandem mill is said to be the first of its
type in South America.
The new tandem cold mill will be
used for manufacturing can stock for
the beverage industry. The products will
comprise strip in widths of up to 2,000mm
and with a minimum final gauge of
0.15mm. The mill will be designed for an
annual capacity of 330,000t.
The key components of this high-
capacity mill are highly efficient roll
bending systems, multizone roll cooling
and a hydraulic roll adjustment system. A
coil preparation station, an off-line strip
inspection facility and a pallet transport
system from SMS Siemag complete the
rolling mill.
