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.

Process Flow

Main equipments according to processflow in turn are as follows:

Manually loading → entry skid→ coil loading trolley I# &II# → pay off reel I#&II# → decoiling scraper I# &II# →5-roller pinch straightener I# &II# → transverse shearerI#&II# → vertical guide roller → welder → crescentshearer → pinch roll → entry accumulator → scale breaker →

tension bridle roll →vertical guide roller → acid pickling trough → washing trough → edge blowingdevice → vertical guide roller →

hot air dryer → tension bridle roll → exit accumulator→ tension bridle roll → transverse shearer → exit pinch roll → recoiler (EPC) →

coil unloading trolley → exit skid → manually unloading

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.
