Embodiment Construction
[0042] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0043] The first embodiment of the present invention provides a method of dynamically centering side guides, such as figure 1 As shown, the method includes:
[0044] S101, when the slab runs to the entrance of the entrance-side guide plate, input a first preset offset, and control the entrance-side guide plate to close to a first opening degree according to the first preset offset and the width of the slab.
[0045] S102, when the...

The invention relates to the technical field of hot rolling strip steel rough rolling, in particular to a method for dynamically centering side guiding plates. The method comprises the following stepsof when a slab is transported to an inlet of an inlet side guiding plate, inputting a first preset deviation quantity, and controlling the inlet side guiding plate to be closed to a first opening degree according to the first preset deviation quantity and the width of the slab; when the slab enters rolling machine equipment in a gripping manner for rolling, inputting a second preset deviation quantity, and controlling the inlet side guiding plate to be closed from the first opening degree to a second opening degree according to the second preset deviation quantity and the width of the slab, wherein the second preset deviation quantity is smaller than the first preset deviation quantity; after the slab is subjected to steel throwing, inputting a third preset deviation quantity, and controlling the inlet side guiding plate to be closed from the second opening degree to a third opening degree according to the third preset deviation quantity and the width of the slab, wherein the third preset deviation quantity is smaller than the second preset deviation quantity. Through the adoption of the method disclosed by the invention, time for rough rolling and net rolling is reduced, and temperature drop of the rough rolling is reduced, so that a production line is low in cost and high in efficiency.
Description
technical field [0001] The invention relates to the technical field of rough rolling of hot-rolled strip steel, in particular to a method and a control device for dynamically centering side guide plates. Background technique [0002] The side guide plates are generally used in the rough rolling process of the conventional hot rolling production line. The side guide plates are generally installed at two positions of the rolling mill, one is the entrance and the other is the exit. The structure of the side guide plates is specifically a pair of side plates facing each other. An operation side plate and a transmission side plate, wherein the operation side plate is restricted by position, and the transmission side plate is not only affected by pressure but also controlled by position. [0003] The side guide plate mainly plays the role of centering the slab, guiding and limiting the deviation of the slab in the hot rolling production line. The side guide plate of the conventio...
