1.   Hydraulic De-Coiler

1.      Hydraulic expand and shrink to tight the inner hole of steel coils.

2.      Inner diameter: Φ480-520, width: 500 mm

3.      10T with simple supporting stand, without coil car.

4.      Fixed the coil to active uncoil, with brake.  

5.      The hydraulic expand and shrink de-coiler is driven by hydraulic, to tight the inner hole of steel coil. 

  

3.Hydraulic Press and Feed Device

1. Hydraulic shovel head, hydraulic power shovel-head etc feeding steel plates.
2. 4KW motor drives the uncoiling rollers to uncoiling the coils. Hydraulic control the press device and shovel table lift up and down and extend and shrink.  
3. Structure: It is welding by steel plates and profiled bar

3.Slitting Machine

1. Specification of blades: Φ340×200×15; material: 6CrW2Si.
2. Electric motor: 30KW frequency conversion control motor to control the speed. Control mode is frequency control.
3. Reducer: cycloidal reducer
4. Slitting speed: ≤ 40m/min.
5. It equips the side guide device, to achieve positioning strip and stop the jumping of strip. Improve the accuracy of slitting. It can shear actively or passively. To achieve different strip thickness accuracy requirements of slitting.
6. Technical Parameters:

Power	45KW
Shaft	Φ180
Material of shaft	40Cr
Blade specification	Φ340×Φ200×10
Material of blade	6CrW2Si

4.Recoiler

1. Structure: hydraulic expand and shrink model.
2. Capacity: 10T with simple supporting stand
3. Motor: 55KW
4. Decelerator: JZQ650, i＝40.17
5. Speed: ≤ 40m/min
6. Overall steel plate cantilever structure
7. Function: It works with the finished steel strips after first pre-dividing and second dividing to insure the even and tight quality of recoiler. Recoiling tension and speed are adjustable.
