Embodiment 1

[0026] This embodiment provides a method for controlling the side guide plate of the coiler to reduce the wear of the wear plate, such as figure 1 As shown, the method includes:

[0027] Step 110: when the strip head enters the side guide, the side guide is closed for the first time;

[0028] Specifically, the embodiment of the present application detects the position of the steel strip through a hot metal detector, such as detecting whether the head of the strip steel enters the side guide plate through a hot metal detector, such as detecting whether the head of the tiller enters the pinch through a hot metal detector. Rolls, for example, use a hot metal detector to detect whether the tail of the strip is about to enter the side guide plate, etc.

[0029] For step 110, the hot metal detector is used to detect whether the strip head enters the side guide plate. When it is detected that the strip steel head enters the side guide plate, the closing process of the side guide pla...

Embodiment 2

[0041] This embodiment provides a method for controlling the side guide plate of the coiler to reduce the wear of the wear plate, such as figure 2 As shown, the method includes:

[0042] Step 210: when the strip head enters the side guide, the side guide is closed for the first time;

[0043] Specifically, the embodiment of the present application detects the position of the steel strip through a hot metal detector, such as detecting whether the head of the strip steel enters the side guide plate through a hot metal detector, such as detecting whether the head of the tiller enters the pinch through a hot metal detector. Rolls, for example, use a hot metal detector to detect whether the tail of the strip is about to enter the side guide plate, etc.

[0044] For step 210, the hot metal detector is used to detect whether the strip head enters the side guide plate. When it is detected that the strip steel head enters the side guide plate, the closing process of the side guide plat...

Abstract

The invention discloses a reeling machine side guide plate control method for reducing wearing of a wear-resisting plate. The method includes the following steps that when the head of strip steel enters a side guide plate, the side guide plate is closed first time; when the head of the strip steel enters a clamping roller, the side guide plate is closed second time; when tension control over a core shaft is built, the side guide plate is closed third time, position control is changed into pressure control, and the control pressure reaches a preset pressure value; and when pressure control is executed a preset time, the side guide plate is opened to the preset position, pressure control is converted into position control. The technical problem that the quality of the edges and the surface of the strip steel are influenced by friction between the edge of the strip steel and the wear-resisting plate of the guide plate is solved, and the technical effects of being high in quality of the edges and the surface of the strip steel, the replacing efficiency of the side guide plate is reduced, and the repairing cost of the side guide plate is reduced are achieved.

Description

technical field [0001] The invention relates to the technical field of metallurgical manufacturing, in particular to a method for controlling side guide plates of a coiler to reduce wear of wear-resistant plates. Background technique [0002] In the metallurgical industry, hot rolling mills generally consist of 6 or 7 finishing mills and 2 to 3 coilers. In order to ensure the beautiful appearance of the steel coil and avoid scratches on the edge of the steel coil during the process of unloading the steel coil, generally the strip steel is centered by applying a certain pressure through the side guide plate during coiling to ensure that the side of the steel coil is even and avoid towering and Stacking fault defects occur. [0003] The inventor finds that there are following deficiencies in the prior art in daily work: [0004] During the pressure control process of the side guide plate, there is high-speed and severe sliding friction between the edge of the strip steel and...
