Technical features of CCM:
Ladle supporting: turret/ladle car.
Tundish car: half-suspending type/suspending type.
Mould: integrated copper pipe/parabolic taper.
Control of strand: cesium-source liquid level automatic control.
Vibration mode: whole leaf-spring/half leaf-spring/sine/non-sine.
Secondary cooling way: automatic cooling water distribution in aerosol/whole cooling water distribution.
Straightening mode: 5-roll continuous strengthening in full arc/AC variable frequency speed regulation.
Dummy bar type: self-adaptive rigid dummy bar.
Cutting mode: automatic narrow-seam high efficient flame cutting machine/hydraulic shear.
Steel shifting mode: mechanical overhead structure.
Control mode: all PLC control/quick shifting between manual mode and automation mode.
Features of Slab CCM:
1. Ladle turret: hydraulic link lifting, with weighing device. Carrying capacity: 240t+240t (two sides).
2. Tundish: 35t, automatic stopper rod mechanism (interlocking with liquid level detector of mold).
3. Half-suspending and double-hydraulic cylinder lifting tundish car.
4. Hydraulic width-adjusting mold.
5. Mold vibration device: hydraulic drive, can adjust the stroke and frequency online and select sine or non-sine vibrating wave.
6. Closely arranged small-diameter roller in continuous bending section.
7. Segment section: continuous reduce roller gap, with split roller and continuous straightening.
8. Dummy bar: chain structure, hook dummy bar head, can mount with roll gap measuring instrument.
9. Dummy stripping device: single hydraulic cylinder top.
10. Dummy bar storage device: skew bridge trolley side storage, composed of dummy bar trolley, trolley transmission device and dummy bar centering device.
11. Flame cutting machine: casting billet cutting and sample cutting.
12. Conveying roller table system: individual transmission, all plain roll, lower cutting roller table of overall translation.
