Pickling lines and tandem cold mills
For a wide range of product applications,
the required strip thickness, flatness and
surface quality can be achieved more
economically by linking the pickling and
cold rolling processes. This delivers
significant improvements with regard to
mill productivity, yield and production
cost savings as a result of the elimination
of strip threading and tailing-out
operations. Reduced strip-head and tailend
losses also contribute to better
overall yield. Our speed optimization
system ensures maximum throughput
rates under all operating conditions, and
maintenance, roll consumption and
manpower requirements are also
lowered. Typical production capacities of
such combined facilities are in the range
of 1.2-2 million t/a.
Pickling line
Pickling lines supplied by Siemens VAI are
characterized by high pickling rates, lowcost
pickling operations, flexible
production, a wide range of product
sizes, qualities, reliable plant operation,
and low maintenance requirements, as
well as compliance the highest standards
for environmental safety.
The pickling model –
SIROLL CIS Faplac®
The SIROLL CIS Faplac® system (Fully
Automatic Pickle Liquor Analysis and
Control) ensures an efficient operation of
the pickling process by compliance of a
proper acid and iron concentration
(waste acid).
The employment of roll and strip
temperature models ensures the
achievement of tight tempera ture
tolerances and the avoidance of
overheating thus prolonging the life of
the emulsion.
In addition the rolling strategies
calculated by the process models are
geared to the minimum use of electrical
energy by making the most efficient use
of the mill with respect to roll force, roll
torque and roll power.
Main benefits:
High pickling throughput rates
Uniformly pickled surfaces
Closed loops of acid, fume and rinse
circulation reduce operation cost in an
environmental-friendly manner
