Problems solved by technology

[0005] The embodiment of the present application provides a method and device for improving the control accuracy of the side guide plate opening degree in finishing rolling, which solves the problem that the side guide plate is worn to varying degrees due to long-term use, which causes the frame amount of the side guide plate to affect the accuracy of the side guide plate opening degree. , resulting in the center line of each side guide plate not being on a straight line, which is a technical problem that is likely to cause a steel jamming accident when rolling the strip steel. It achieves the action control of the side guide plate and reduces the amount of frame caused by the wear of the side guide plate. The opening of the side guide plate Improve the control accuracy of the side guide plates of each frame, make the center line of the side guide plates of each frame in a straight line, improve the stability of strip threading and rolling, reduce the situation of flicking and rolling, and improve the production line The technical effect of the control of various indicators

Embodiment 1

[0027] A method for improving the control accuracy of the opening degree of the side guide plate of the finishing rolling provided by the embodiment of the present application includes referring to figure 1 , image 3 :

[0028] Step 110: Obtain the first set value of the side guide plate 1;

[0029] Specifically, the first set value is the value set for the side guide plate 1 in the primary monitoring interface, wherein the first set value can be set according to the range of the opening degree 2 of the side guide plate Certainly. When the opening degree 2 of the side guide plate ranges from 850mm to 2350mm, the first set value can be any value within the opening degree range of the side guide plate.

[0030] Step 120: According to the first set value, determine that the side guide plate 1 is closed to the first opening degree, and perform calibration;

[0031] Specifically, the first opening degree is the opening degree of the side guide plate under the premise that the ...

Abstract

The invention provides a method and device for improving the opening degree control precision of a finish rolling side guide plate, and relates to the technical field of silicon steel production. The first set value of the side guide plate is obtained; according to the first set value, it is determined that the side guide plate is closed to the first opening degree, and calibration is conducted; when strip steel arrives at an inlet of a finishing mill, the second set value of the side guide plate is obtained; the side guide plate is opened to the third opening degree, the side guide plate is closed to the second opening degree; after the strip steel enters a roller, the third set value of the side guide plate is obtained; it is determined that the side guide plate is closed to the fourth opening degree; before the tail of the strip steel arrives at the side guide plate, the fourth set value of the side guide plate is obtained; and it is determined that the side guide plate is opened to the fifth opening degree. The technical problem that due to the frame allowance of the side guide plate, the opening degree precision is influenced, and consequently steel clamping is likely to be caused during strip steel rolling is solved, and the technical effects that the influences of the frame allowance of the side guide plate on the opening degree precision are weakened, and the strip steel threading stability is improved are achieved.

Description

technical field [0001] The invention relates to the technical field of silicon steel production, in particular to a method and a device for improving the control precision of the opening degree of the finish rolling side guide plate. Background technique [0002] In the strip rolling process, the accuracy of the opening of the side guide plate of the finishing mill directly affects the strip threading stability of the finishing mill, and plays a decisive role in the strip running and leveling of the rolling operator. [0003] However, in the process of realizing the technical solution of the invention in the embodiment of the present application, the inventor of the present application found that the above-mentioned technology has at least the following technical problems: [0004] Due to the wear and tear of the side guide plates in different degrees after long-term use, the frame volume of the side guide plates will be generated, which will affect the opening accuracy of t...
