Problems solved by technology

[0005] The speed limit method can be used for traditional flicking, that is, when the remaining strip length on the uncoiler is less than X1 meters, the speed setting value is reduced to V1; when the remaining strip length on the uncoiler is less than X2 meters, the speed setting value is reduced again Reduced to V2; this step-like speed adjustment can be used in some occasions with low process requirements, but it has the disadvantages of low production efficiency and insufficient safety and reliability.

Embodiment 1

[0028] Embodiment 1. Control method for high-speed tail drift of uncoiler in cold rolling processing line

[0029] The method is: when the remaining strip length COIL on the uncoiler is less than a certain value (generally set to 250 meters), a tail deceleration positioning process is started, and after the deceleration positioning starts, the remaining strip length COIL on the uncoiler is always detected. And adjust the positioning setting value SETP in real time, because the actual distance DIS traveled by the strip steel after the positioning starts is recorded in real time by the No. It will be adjusted continuously; when the tail of the belt is thrown over the synchronous grating, the last positioning setting value will be adjusted synchronously. When the remaining distance of positioning POS becomes zero, the unit will stop, cut the tail of the belt, and the tail-flicking will be completed.

Embodiment 2

[0046] Embodiment 2. The specific application of the control method for the high-speed tail drift of the uncoiler of the cold rolling processing line

[0047] Taking Angang's 1450mm cold rolling production line engineering pickling-rolling mill combined unit as an example to verify the effectiveness of the high-speed tailing control method for the uncoiler of the cold rolling treatment line of the present invention. details as follows:

[0048] (1) Determine the important parameters of high-speed tail drift:

[0049] The distance R_PT from synchronous grating 2 to double shear 4 is 11.44m;

[0050] Under normal circumstances, the number of waste pieces set by the HMI screen or Level2 computer system is 3 pieces, and the length of each piece of waste material set by the HMI screen or Level2 computer system is 1.1m, so the tail length OFFS that needs to be cut is 3.3m;

[0051] In this project, No. 1 tension roller 5 is equipped with a speed measuring code disc, which is used ...

Abstract

The invention relates to a control method for high-speed drifting of a cold rolling treatment line decoiler. The control method is characterized by comprising the following steps: when the length COIL of the residual band steel on the decoiler is less than a certain set value, starting a belt tail speed-reducing positioning process; after the speed-reducing positioning starts, detecting the length COIL of the residual band steel on the decoiler all the time and adjusting the positioning set value SETP in real time; and continuously adjusting the positioning residual distance POS, wherein the POS is equal to (SETP-DIS). A positioning speed Vpos is generated corresponding to the positioning residual distance POS; when the POS is reduced gradually to be zero, the Vpos is also reduced gradually to be zero, so when the positioning residual distance POS is changed into zero, the unit stops, the belt tail is cut, and the high-speed drifting of the cold rolling treatment line decoiler is finished. By adoption of the control method, high safety and reliability are achieved; and continuous production capacity and annual output of the cold rolling treatment line decoiler unit can be guaranteed.

Description

technical field [0001] The invention relates to the field of uncoilers, in particular to a control method for high-speed tail drift of an uncoiler in a cold rolling processing line. Background technique [0002] As a continuous production line, the cold rolling processing line unit adopts a highly automated control system, which can complete many actions independently, greatly reducing the labor intensity of the operators. The entrance uncoiler can automatically drift at high speed after the production of a single coil of strip steel, so that the operator can focus more on other issues in the production of the unit. [0003] High-speed tail flick needs to accomplish two goals: one is to stop the belt tail in time to ensure that the belt tail can reliably stop in front of the slitter or welding machine; the other is to make the deceleration of the unit as late as possible to ensure production Efficiency and volume of entry loops. [0004] At present, the uncoiler of the col...
