Embodiment Construction

[0043] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0044] Such as image 3 Shown, the control method of the side guide plate of the hot rolling coiler of the present invention is as follows:

[0045] (1) Belt threading stage: the control unit controls the opening degree adjustment mechanism of the side guide plate to adjust the opening degree of the side guide plate to the first opening degree S 1 ,

[0046] S 1 =B+W+B 1 ,

[0047] where S 1 is the first opening, that is, the opening of the side guide plate in the belt threading stage,

[0048] B is the strip width,

[0049] W is the short-stroke opening of the side guide plate,

[0050] B 1 add value to standby;

[0051] The strip threading stage refers to the stage from when the head of the strip exits the finishing stand to when the head bites into the pinch roller. see image 3 In part a, the side guide plate mainly plays a guidi...

Abstract

The invention discloses a control method of a side guide plate of a hot-rolling coiler. The method comprises the stage one of strip penetrating, wherein the opening degree of the side guide plate is adjusted to the first opening degree S1; the stage two of head rolling, wherein the opening degree of the side guide plate is adjusted to the second opening degree S2; the stage three of middle portionrolling, wherein the opening degree of the side guide plate is reduced step by step, a video monitoring unit monitors the side guide plate and strip steel, when sparks generated by rubbing between the side guide plate and the edge portion of the strip steel is monitored, a control unit controls a side guide plate opening degree adjusting mechanism to stop reducing the opening degree of the side guide plate, the opening degree of the side guide plate is recorded at the moment as the edge finding opening degree S4, and then the opening degree of the side guide plate is adjusted to the third opening degree S3; and stage four of tail rolling, wherein the opening degree of the side guide plate is adjusted to the edge finding opening degree S4. According to the control method of the side guideplate of the hot-rolling coiler, the roll shape quality is ensured, abrasion to the side guide plate is reduced, replacing frequency is reduced, and operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of hot rolling, in particular to a method for controlling side guide plates of a hot rolling coiler. Background technique [0002] The coiler is an important equipment of the hot rolling production line, which is used to coil the hot rolled steel strip into steel coils. The coiler is located behind the finish rolling unit and is the last process of the hot rolling production line. See figure 1 and figure 2 , The strip 1 is transported from the finish rolling unit to the coiler unit by the roller table 2, and enters the pinch roller 4 through the alignment of the side guide plate 3. The pinch rolls convey the strip head to the mandrel 5 . After the reel 5 is wound on the steel strip 1, tension is applied to it to ensure that the coil quality is qualified. [0003] After the strip steel is rolled into coils by the coiler, the inner coil layer of some steel coils protrudes to one side. When the protrudin...
