Continuous & Push-pull type of Steel strip pickling line
with annual 450,000TPY
JJRS is professional on turn-key projects, from general planning,
designing, to manufacturing, installing, commissioning and
servicing. Besides, our business also covers single equipment’s
designing, manufacturing and installing, as well as electric
transmission, control system and spare parts. All basing on these
supporting businesses, we mark out a developing strategy that
taking metal strip intensive processing and color coating
production lines as main, and the associated industry products as
supplement.
Pickling of stainless steel Stainless steel exists in many
different alloys and qualities, depending on the needs of the
different material applications. It comprises austenitic, ferritic,
and martensitic grades. It is available in the form of cold rolled
and hot rolled strip. A re-crystallizing treatment in annealing
furnaces is required for both hot and cold rolled strip before it
can be used or cold rolled again; thus, repeated descaling of
stainless steel strip needs to be performed, to remove mill scale
as well as scale resulting from the annealing process.
With respect to carbon steel, the scale from stainless steel is
more difficult to remove. Moreover, the hot rolling and annealing
processes lead to the diffusion of chromium from the upper layer of
the base material into the scale. The resulting chromium depleted
layer on the strip surface needs to be removed by the pickling
process.
The push-pull pickling line
For the pickling of up to 1,000,000 tons of strip per year
depending on the product mix, Push-Pull Pickling Lines offer
significant advantages in terms of investment costs and operational
flexibility (frequent change of strip dimensions and steel grades)
with uniquely designed V-shape flat pickling tanks.
Continuous Acid Pickling Line
Our Continuous Pickling Lines feature a modular design, high
pickling efficiency, economical operation and are integrated with
the latest advanced technologies.The line can be also combined with
a Galvanizing Line (CPGL – Continuous Pickling and Galvanizing
Line).
