Introduction:

Middle thick plate cut-to-length line can meet customer's request of max line speed 40m/min by uncoiling & leveling a coil strip, and then shearing the leveled flat strip to certain length of sheets.

This coil CTL line is especially suitable for CR, HR carbon steel coils, GI, PPGI steel plates.

The plate cut-to-length line (coil CTL line) has one leveling machine driven by DC or AC motor, and the length-fixing is by encoder, shearing style is stop-shear.

The plate cut-to-length line (coil CTL line)  is composed of: coil loading car, Double-mandrel decoiler, coil-head guide, press & shoveling equipment, pinch-feeding, transmit table, side guide, Leveling machine, Final sheet sending out equipment, length-fixing encoder, Hydraulic shearing machine, delivery roll table, pneumatically piling-up bed, hydraulic system, electric control system, etc.

The middle thick plate cut-to-length line fit steel coils with thickness: (1~6mm, 2~8mm, 3-10mm) and changeable width, and length of finished sheets depend on customer's practical need.

Advantages & Characteristics for this coil CTL line:

1. High precision

  Line speed can be up to 30m/min, 7-8pcs/min 2000mm Length sheets in average.

  Leveling precision: ±1mm/㎡

  Sheet length precision: ±0.5mm/m

  Sheet diagonal length precision: ±0.5mm/m

2. Coils differ in coil weight, when max coil weight is small, usually single mandrel (cantilever) uncoiler is adopted; when max coil weight is big, double-mandrel decoiler with three steps or double-cone decoiler is adopted for this thick plate cut-to-length line (coil CTL line) .

3. To make flat steel sheets, the diameter of leveling rollers should be scientifically proper, we confirm diameter of leveling rollers by actual experiences and engineering calculation.

4. The backup rollers installed in backup bracket can tightly back leveling rollers up to make sure no deformation of leveling rollers while leveling.

5. Final-sheet sending-out equipment sends finished sheets onto pneumatic packing platform.

6. We adopt good quality parts supplied by famous brand company, e.g. Mitsubishi PLC control, Yuken/Fuxin hydraulic parts, HRB/ZWZ/SKF bearings, etc. This can ensure good performance of coil CTL line.
