Cold rolled strip shape closed loop measurement and control system1 ScopeThis standard specifies the cold strip strip closed-loop control system structure, technical requirements and system testing. This standard applies to cold-rolled strip mill, flat-plate machine closed-loop control, other types of rolling equipment, flat-shaped closed-loop control can refer to use.2 Normative referencesThe following documents for the application of this document is essential. For dated references, only the dated version applies to this article Pieces. For undated references, the latest edition (including all amendments) applies to this document. GB/T 8541 forging terminology GB/T 34902 cold strip contact with the shape meter JB/T 7807 rolling machine terminology3 Terms and definitionsGB/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. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 34901-2017_English be delivered?Answer: Upon your order, we will start to translate GB/T 34901-2017_English as soon as possible, and keep you informed of the progress.
