Coil loading (unloading) car and saddle 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 and at the same time the pinch roll also can establish the tension for the steel strip in the payoff section.
During the hot rolling process, a layer of brittle and hard oxide is formed on the surface of the steel coil. Before the cold rolling process, the oxide on the surface of the coil must be removed. This process is usually completed by the pickling unit.The pickling unit is divided into push-pull pickling production line and continuous pickling production line.Pickling line energy medium and consumption.Water for production Name | Industry wate | Soft water | Steam | Desalted water |

Line Main Properties:1.Push-pull pickling adopts advanced shallow turbuleimmernt pickling process, with short pickling time and high pickling efficiency. Push-pull pickling can be divided into six sections, each section has its own outer heating and pickling system, through adjusting the temperature of every pickling sections to achieve the best pickling effect.2.Continuous pickling adopts turbulent shallow pickling process with extinct advantages. The liquid height inside the acid tank is just 150mm, the inner and outer cover of the acid tanks, all can reduce the evaporation and improve the turbulence speed of the acid liquid.3.Continuous pickling line has three acid tanks, each of them has separated outer heating system and acid recycled system. Through adjusting the temperature, concentration and the turbulence speed of every acid tank to achieve the best acid effect.4.Using five-stage counter follow cascade rinse system, only need few rinsing water. Though controlling the accuracy of the conductivity in the last rinsing section to ensure the rinse quality of the strip surface.5.Continuous pickling line has set 800t rolled skin pass mill to improve the defects of the strip shape and the quality of the strip surface, as well as eliminate part of the yield platform, and improve the product competitiveness.6. Continuous pickling adopt reliable technical, stable running double head rotate tower side trimmer, the open degree of the shear blade, overlap amount, side seam can be adjusted automatically.
