Steel Coil Slitting Line

Steel Coil Slitting Line


The steel coil slitting line, composed of uncoils, feeding, sltter and other equipments, is a production line of uncoiling, slitting and coiling slit steel strips. This kind of production line is able to cut the wide steel coil into narrow steel coils of certain dimension in the direction of length. This steel coil will be an input preparation for those processes, such as steel strip rolling, ERW pipe welding, cold bending and profiles forming, steel plate punching. All kinds of metal strips can be cut by cutting tools (disc knives) of different materials.
The main function of this of this metal steel coil slitting line apply to cut the width of coils into smaller coils, and any thickness is available.

Features of Steel Coil Slitting Line:

1. After slitting, the strips need coiling on the recoiling mandrel.
2. Commonly, the D.C. drives are used on slitter and coiler, and uncoiling is passive with brake, so that the different mandrel speeds are retained in the same speed Therefore, the line speed is attained too.

3. For faster speeds and thinner strips a loop pit is provided for installation before recoiling with tensioner equipment, another pit loop is after uncoiling and before slitting.

4. PLC and HMI make the whole slitting line work in automatic mode at high speed.

5. tensioner unit has hydraulic wool pads style and hydraulic air hose style to choose.

6. recoiling mandres can be segments of clearances or seamless segments for different metal strips coiling.

7. Any different specification is available, as we can offer a comprehensive range of metal coil slitting proposals, We design and produce products in accordance with customers needs.

Application of Steel Coil Slitting Line:

This sheet metal slitting machine is suitable to process cold-rolled steel, hot-rolled steel, low carbon steel, silicon electric steel, high quality high carbon steel, stainless steel, galvanized steel, color steel plates and the various metal materials.

The dimensions of narrow baby strips are calculated out according to the inputs of next strip processing lines:

stud or keel roll forming machine need thin and narrow strips.

C/Z purlins need 1-3mm thickness 160-500mm plain carbon steel galvanized steel strips

ERW pipes need 0.8-4mm 30-500mm low carbon steel low alloy steel steel strips.

Cold rolling mill needs 200-300mm, 250-450mm, 400-600mm steel strips....


the slitting accessories arranging is very important work of slitting machine operator who should calculate out the required steel strips sizes and quantity to arrange slitting knives and spacers, to take full use of the steel coil slitting line capacity
