Strip Annealing Pickling Line In Steel Industry Annual 450000TPY

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).
