GB/T 8541, GB/T 34902, JB/T 7807 and defined by the following terms and definitions apply to this document.
3.1
Measured flatness signal measuredshapesignal
Shape meter output after the measurement of noise and error compensation can reflect the state of the online plate shape effective signal.
3.2
Shape pattern recognition shapepatternrecognition
A complex plate-shaped curve is decomposed into 1, 2, 3, 4 and higher plate-shaped components or plate-shaped pattern, and then integrated into them
Linear combination.
3.3
Flat target curve shapestandardcurve
Flat standard curve
In order to consider the rolling process requirements and follow-up processing requirements and the development of the shape control target curve.
Note. During the process of plate shape control, the measured plate shape curve is approximated to the plate shape target curve by comprehensively using various plate shape control measures, even though the measured plate shape approaches the target
Shape.
3.4
Shape control means shapecontrolmeans
Can effectively change the shape of the roll gap, strip shape state of the mechanical device, there are inclined roll, bending roll, traverse roll and segmented cold
But roll and so on.
3.5
Shape control efficiency shapecontrolefficiency
The amount of change in the unit change of a plate-shaped control means the amount of change caused by the plate-shaped components or the strip shape at each point in the horizontal direction of the strip.
