  • Cut to length line for making the coil to plate
    Cut to length line is also called shearing line, uncoiling line, and cross-cutting line. It is used to decoiler, leveling, and cut steel coils into flat sheets of required length and stack them. It is suitable for processing cold-rolled and hot-rolled carbon steel, silicon steel, stainless steel and various metal materials after surface coating.

    1. structure    

    The machine is a single-head cantilever hydraulic expansion and contraction unwinder, which is composed of a main shaft part and a transmission part.

    (1) The main shaft part is the core part of the machine. Its four blocks are connected to the sliding sleeve through T-shaped slanting blocks and are simultaneously sleeved on the hollow spindle. The core is connected to the sliding sleeve. The fan blocks expand and contract at the same time. When the fan block shrinks, it is beneficial to roll up, and when the fan block is opened, the steel coil is tightened to complete the unwinding.

    (2) The pressure roller is located behind the unwinder. The pressing arm is controlled by the oil cylinder to drive the cantilever to be pressed down and picked up. When feeding, the cantilever pressing roller is pressed to press the steel coil to prevent loosening and facilitate the feeding.(3) The transmission part is located outside the frame. The motor and reducer drive the main shaft of the unwinder through the gear to rotate, and it can also realize unwinding and rewinding.

    2. Technical Parameters

    (1) Steel coil width: 500mm-1500mm

    (2) Steel coil weight: 10T

    (3) Cylinder stroke: 600mm

    Motor running: 2.2kw

    15-axis dual-type precision leveling machine

    1. Leveling rollers: 15

    2. Leveling roller diameter: 120mm

    3. Leveling roller material 45 # steel

    4. Motor power: 22KW

    5. The leveling effect is according to the first grade coil, except for scrap or secondary board.

    6. Leveling roller material: 45 # steel.

    7.  After tempering, quenching and grinding, the surface hardness reaches HRC58-62, and the surface finish is Ra1.6mm.

    8. The upper row of work rolls are lifted vertically by a motor drive.

    9. Roller bearings are used for the work roll bearings, which have a high bearing capacity and a long service life.

    Main force system: One motor is driven centrally and driven by the universal joint of the reducer transmission box.



    1. It uses the 2 groups of magic eyes to control the speed buffer between decoiler and slitting machines.

    2. Magic eye is controlled by PLC.

    3. Function: it is used to eliminate the different speed and make the plates which in wrong rail to back the right way. At first, it is used the oil cylinder to lifting the supporting and transition plates to make the head pass. When working, the transition and supporting plates lift down, the steel plates will be stored in the pit.
