Embodiment 1

[0054] figure 1 It is a schematic flow chart of a method for controlling the tailing of the winding-assisting roller in the embodiment of the present invention. Such as Figure 1-3 As shown, the embodiment of the present invention provides a method for controlling the tailing of the winding-assisting roller, which is applied to a coiler. There are position sensors and pressure sensors, and there is a metal detector 2 at the front 5 meters of the pinch roller 1 of the coiler, and the method includes:

[0055] Step 110: Obtain detection information of the strip tail.

[0056] Specifically, the strip steel is detected in real time by the metal detector 2 arranged in front of the pinch roller 1, and when the tail of the strip leaves the detection range of the metal detector 2, it indicates that the When the strip steel has completely entered the working range of the coiler, it is necessary to carry out tail pressing work. After the metal detector 2 detects the loss, that is, wh...

Embodiment 2

[0074] Based on the same inventive idea as the method for controlling the tailing of the roll-assisting roller in the foregoing embodiments, the present invention provides a control device for the tailing of the roll-assisting roll, which is applied to a coiler, and the coiler has two More than one roll-assisting roll, position sensors and pressure sensors are installed in the hydraulic cylinder of the roll-assisting roll, and a metal detector 2 is arranged at the front 5 meters of the pinch roll 1 of the coiler, such as Figure 4 As shown, the device includes:

[0075] A first obtaining unit 11, the first obtaining unit 11 is used to obtain strip tail detection information;

[0076] A first sending unit 12, the first sending unit 12 is configured to send a winding-assisting roller closing signal according to the tail detection information;

[0077] The first determining unit 13, the first determining unit 13 is used to control the winding-assisting roller to close toward the...

Abstract

The invention provides a wrapper roller tail pressing control method and device. The method comprises the steps that tail detection information of strip steel is obtained; a wrapper roller closing signal is sent according to the tail detection information; according to the wrapper roller closing signal, wrapper rollers are controlled to be closed towards the strip steel, after the wrapper rollersmake contact with the strip steel, the first wrapper roller is determined, keeps the preset pressure and presses the strip steel; and pressing force of the second wrapper rollers to the strip steel iscontrolled to be reduced, wherein the wrapper rollers, except the first wrapper roller, are named as the second wrapper rollers. The technical problems that in the prior art, multi-wrapper-roller high-pressure tail pressing treatment is adopted, roller consumption of wrapper rollers is increased, and thus, indentations occur to the surface of strip steel are solved. The technical effects that thesituation that all the wrapper rollers make contact with the surface of the strip steel with high pressure is avoided, the roller consumption probability and the strip steel surface indentation probability are reduced, the tail pressing effect is ensured, in addition, the automation degree is high, and the manpower cost is reduced are achieved.

Description

technical field [0001] The invention relates to the technical field of winding-assisting roller control, in particular to a method for controlling tailing of winding-assisting rollers. Background technique [0002] At present, the tailing automation control of the domestic hot rolling coiler (such as 3 auxiliary arms) usually adopts one to three auxiliary rollers (optional). The function of tail pressing is to prevent the tail of the strip from entering the coiler at high speed and impact on the equipment, to fix the tail and unload the coil, and to control the coil shape when the tail is out of tension. Through long-term on-site observation, when there are many thin specifications, 2-3 roll-helping rollers are used to press the tail to avoid the outer tower caused by loss of tension. [0003] However, in the process of implementing the technical solutions in the embodiments of the present application, the applicant of the present invention found that the above-mentioned pr...
