Continuous Acid Pickling Line
For continuous acid pickling line, the headand rear parts of two
different coils shall be welded together, both entry andexit of
process sections are equipped with accumulators to guarantee
acontinuous operation. Generally when the annual capacity exceeds
700,000 tons,continuous picking line will be adopted.

At the entrance, there are two roll-opening mandrels and roller
anti-roll barrel. The rollers are connected to each other via the
stitcher to ensure the continuity of production at the input part.
In the tension leveler, the oxide (tufal)layer is broken and the
pickling process is facilitated. Also the surface smoothness is
provided by lengthening. Pickled sheet which is cleaned from the
oxide layer on the surface by passing through bath tanks (3
pieces); the surface is rinsed with RO water while passing through
the rinse tank and then dried with hot air in the dryer. In the
edge trimming unit; the desired width of the sheet is achieved by
trimming from both sides by means of circular blades. In the
Electrostatic Oiling Machine, both surfaces of the sheet are oiled
with anticorrosive oil in desired amounts. The amount of oiling is
0.2-3.0 gr/m2 for one surface. The stitch points are trimmed
vertically, the two rolls are separated from each other, and is
rolled on the mandrel and produced as a roll.
