Specification of the pickling line
2.1. General introduction
This pickling line is pull-push type and adopts the advanced
shallow tank turbulent flow pickling technology. The line provided
is mature and reliable and proved by producing practice.
.
The equipments of the line excepting the payoff reel and tension
reel will adopt the aerial arrangement. The running level of the
steel strip is +2500. The uncoiling, pickling and coiling will be
finished online completely.It has the convenient operation, less
fault,high efficiency working and other features. It can satisfy
users with stable production and long-term running.

The coil loading (unloading) car is used for transporting the steel
coil onto the coil drum of the payoff reel or transporting the
steel coil onto the special equipment for temporary storing from
the coil drum of the payoff reel.
The coil loading (unloading) car is composed of the fixed saddle
and the horizontal transverse moving car with the vertical lifting
and falling saddle.
Equipment performance:
Max. loading weight: 25MT
Outer diameter of steel coil: Φ1000-Φ2000mm
Lifting and falling height of saddle: 1000mm
Quantity of fixed saddle: 2 pairs or 3
2.2.1.2. Payoff reel
The payoff reel is used for uncoiling the steel coil into the strip
and providing the suitable tension to the steel strip.
The payoff reel is the hydraulic flexible cantilever type floating
payoff reel with the auxiliary support and it is mainly composed of
the payoff reel,transverse moving mechanism and auxiliary support,
etc.
Equipment performance
Effective length of coil drum: L=1750mm
Diameter of coil drum: D=Φ610mm
Flexible stroke: ΔD=40mm
Payoff tension (max): 20KN
2.2.1.3.Pressing roll device and opening device
The opening device is used for fetching out the head of the steel
coil and transporting the strip head to the next procedure.
The opening device is composed of the movable frame with the
pressing roll driven by the oil motor and the flexible and wobbly
uncoiling shovel plate.
2.2.1.4. Side guiding centering device
The side guiding centering device is used for guiding and position
controlling the running steel strip.
The side guiding centering device is composed of the vertical roll
stand and adjusting device of the vertical roll gap.
Equipment performance
Vertical roll: Φ150×150mm
Gap: 750 mm
2.2.1.5. 9-roll straightening leveler
The straightening leveler is mainly used for straightening the head
of the steel strip for easily sequent treating the head of the
steel strip and threading.The pinch roll of the straightening
leveler deliver the head of the strip into to the straightening
leveler.
