Push-pull pickling line

Seaworthy packing

1. Description:

Push-pull pickling line, higher quality, simply operation, good applicability

Low consumption and fewer faults, so it is very fit for medium and small cold rolling plant

The Push-pull pickling line capacity is among 100,000~600,000 tons annually.

It can acid washing many kinds of incoming material

2. Push-pull pickling line technology parameter:

Process method: push-pull shallow slot turbulence hydrochloric acid

Pickling medium: hydrochloric acid (≥31%)

Pickling density: 8~18%

Pickling time: minimum: 25-30s

Pickling temperature: 65~85°C

Acid density: Max 200 g/L HCl 120g/LFe²

Driven way: SIEMENS AC frequency control system in main driving

3. Data

Following is the data for push-pull pickling hot rolled strip with the annual output of 400,000 tons

 4. Process Flow of Push-pull pickling line:

Pre-uncoiling station:

Loading platform → entry coil car → pay-off reel → pinch straightener → comer shear → shear pickling unit

Pickling line:

Manually loading → pay-off reel → pinch straightener → entry shear → riveter pinch roll→ back washing → pickling → water washing → drying → looper →disc shear → exit shear → electrostatic oiling → recoiler → manually unloading
