4. Features:
1)Uncoiler is equipped with CPC automatic centering function, which
adopts EMG products from Germany, and improves the centering
response speed and position control accuracy.
2)Rolling line adjustment equipment adopts stepwise wedge
combination adjustment, and the input roll diameter can quickly and
automatically control the stepwise wedge displacement of the oil
cylinder drive to the right position, realizing automatic and quick
adjustment of the rolling line
3)Positive and negative bending of the work roll; the intermediate
roll has transverse moving presetting, locking, and positive
bending control measure. The bending roll can be controlled from
single side; rollers are equipped with subsection cooling and roll
shape adjustment. Multiple-plate-shape control measure is able to
better control the plate shape of finished strips.
4)Double-station roll changing carriage is adopted, which realizes
the swift changing between the work roll and the intermediate
roll.
5）Roll system of the rolling mill, the turning roll, and the oil
removal roll bearing adopt air-oil lubrication, which can prolong
the bearings life and reduce oil consumption, pollution and
maintenance quantity with high lubrication efficiency.
6）Imported X-ray thickness gauge is adopted, improving the
thickness precision of finished strips.AGC automatic system adopts
S7-400+FM458 structure, which makes the utmost use of the
controller and matches the quick response of the high-speed rolling
mill.
7）In the second-level automation controlled by AGC, rolling
schedule is further improved.
8）All key components and parts of hydaulic system adopt import
components and parts, which improves system reliability.
9）Hydaulic AGC system is equipped with advanced functions of
constant roll gap control, constant roll force control, constant
thickness control, mass flow control, thickness precontrol,
tension/speed automatic control, etc
