3. Brief introduction of Steel Slitting Process Explained

ZT-10X1600mm steel coil slitting line is used for slitting the hot rolled steel coils to prepare for the next process.

1.  V-shape base

◆It is used to load the coil, to prevent damaging the car by putting the coil into the car directly.

◆It is one pair (two pieces), length 1000mm, width 480mm.

     2. Hydraulic entry coil car

◆Hydraulic coil car is composed of base, axle, wheels, bearing and guide rods, guide bushing, up-supporting seat, rolling wheel, hydraulic lifting cylinder, and hydraulic motor.

   3. Double-head decoiler

◆Decoiler is a pair of taper-shaped uncoiling machines. It is composed of a linear model base, frame, decoiler shaft, taper plate, and hydraulic pushing device. One of the decoilers is equipped with a brake

◆Parameters:

Item	Parameters	Quantity
Capacity	20T
Main bearing for decoiler	24140	sets
Design model	Taper-shaped	1 pair
Expand range	φ508mm—φ760mm
centering cylinder	Diameter φ125mm, stroke 1100mm	2 units

◆When the coil car lifts the steel coils and the coil diameter center is aimed at the decoiler center. Two decoilers against the coils.  The two decoilers can be centered independently, also can be centered together to load the coils. When the coil is not in the production center, the double decoiler can move together to the left or right accordingly. When uncoiling, stop the brake, and when you stop running, start the brake.

4. Press and pinch and pre-leveler device(45KW DC)

◆This is composed of a bottom-stand(frame), hydraulic pressing and guiding arm, hydraulic shovel-head device, pinch and preliminary leveling device, power device, etc.

◆Hydraulic pressing & guiding device is composed of hydraulic pressing and guiding arm, pressing and guiding wheel(covered by rubber), sprocket wheel, chain, accompanied by motor, etc.

◆Hydraulic shovel-head device is composed of the shovel-head body, the hydraulic shovel-head, balanced device for the hydraulic shovel-head.

◆Hydraulic pinch and preliminary leveling machine is composed of slide-stand, pinch roller(2pcs), hydraulic pinch device, 5pcs of pre-leveling rollers, hydraulic pre-leveling device, etc.

◆Power device for pinch is composed of a 45 kW DC speed control motor, decelerator, gear distributor case, clutch, one group spindle, etc.

Item	Parameters	Quantity
press motor	7.5Kw Cycloid motor 7.5KW	1   unit
pinch roller motor	45KW DC	1   unit
Press cylinder	Piston diameter φ160mm and stroke 770mm	2 pcs in synchronization
Pinch rollers and pre-leveling rollers	Diameter:φ220mm, material 40Cr, hardness: HRC 48-52	2 pcs for each
Bearing	Model: 217	16sets

◆Brief introduction: The steel coils press the arm to press down. Cut off the belts and run the press wheel by the motor to make the steel head move forward. Expand the Hydraulic shovel-head device and adjust the balance cylinder to control the height of the shovel-head. Once receiving the steel head, lift up and down the hydraulic head-leveling device to press and straighten the head to ensure the head can pass the press and pinch device smoothly. Adjust the pre-leveling roller to feed the pre-leveled sheets to the roller table.

5. 
   

   Hydraulic Head Cutter

◆shear model: cut from up to down, which is coordinated with the signal directly from the encoder and shear automatically

◆Automatic control of the shearing

◆ Four-sided cutter, the material is H13K, a nd it can shear a 10mm steel plate safely after heat treatment

6. Roller table

◆It is composed of a frame, rollers, a supporting plate, and a bearing seat.

Width: 1600mm, length: 1.6 m

Roller diameter: 140mm, supporting bearing 212: 8pcs

◆Brief description： The roller table is used to feed the sheets, and the roller design is to prevent the sheets from scratching the table directly and protect the sheets.

7. Side guide device

◆ The side guide device is composed of the linear model base, movable plate, adjustment device, and stand rollers.

◆Parameters

Thickness Name	2~10mm
Adjustment width	800~1600mm
stand roller quantity	4
Press roller diameter	Φ120mm
HRC Surface hardness	50~54
main bearings	7212，8212:2 sets for each，314：8 Set

◆Brief introduction: The side guide device is to guide the sheets from the pre-leveling device and centering to the slitting machine to avoid left or right deviation.

8. Slitting machine（160KW DC）

◆ The slitting machine is one of the important parts of the whole line.

◆Power part: consists of bottom base, decelerator, 160KW DC motor, and universal coupling as well as gear distributing case, coupler, spindle, connecting cover, etc.
