Continuous Pickling line
1. Specification:
strip thickness:1.2-6.0mm
strip width:500-1630mm
coil weight: max.30t
speed:40-180m/min
2. Technical parameter for the pickling line:
Continuous pickling line
Pickling medium:hydrochloric acid(≥31%)
Pickling density :8-18%
Pickling time:miumum:25-30s
Pickling temperature:65-85°c
Acid denstiy :Max 200g/L HCL 5g/Fe³+ 125g/L Fe²
Driven way :adopt SIMENS AC frequency control system in main driving
3.Continous pickling line,characteristic is higer efficiency,high output and low electric consumption etc, the line can produce 600 000- 1200 000 tons/year. Following is the data for continuous pickling hot rolled strip with the annual yield of 800 000 tons.
| Acid | output | stirp thickness | strip width | coil weight | line speed |
| HCL | 800 000t/y | 1.2-6.0mm | 500-1630mm | Max 30t | Max 180m/min |
4. Process Flow of the pickling line:
