Continuous Acid Pickling Line XLY customizable high precision steel sheet acid pickling line
Continuous Pickling Line
For continuous acid pickling line, the head and tail of two different coils shall be welded together; either entry or exit of processing section is equipped with looper to guarantee a continuous operation. Generally the annual capacity exceeding 700,000 tons, continuous picking line will be adopted.
Acid picking line is one of the important procedures in cold rolling steel strip production, the aims of acid pickling are to remove the ferric oxide existing in steel strip surface, adjust weight of each coil, shear off chapped edge, and to obtain qualified raw material for the next coming cold rolling process. According to the technology, acid pickling can be sorted into push-pull and continuous modes.
Main equipments in process flow as follows:
Manually loading → entry saddle → coil loading trolley I# &II# → decoiler I# &II# → decoiling scraper I# &II# → 5-roller pinch straightener I# &II# → crosscut shearer I# &II# → vertical guide roller → welder → crescent shearer → pinch machine → entry looper → scale breaker → tensioner → vertical guide roller → acid pickling trough → washing trough → edge blowing device → vertical guide roller → hot air dryer → tensioner → exit looper → tensioner → crosscut shearer → exit pinch machine → recoiler (EPC) → coil unloading trolley → exit saddle → manually unloading
