annealing and pickling line process with bridle roll pinch roll 700mm 1550mm

700mm~1550mm Innovative continuous pickling line

with pay off reel, bridle roll, pinch roll

Continuous Acid Pickling Line with vertical guide roller, bridle roll, pinch roll, pay off reel

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.

In continuous lines, the process section runs at a constant speed. Such installations are cost-effective due to simplicity of the accumulator designs.

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# →
