Abstract

The invention discloses a plate shape control method, device and equipment in the production process of hot-rolled strip steel. The method comprises the following steps: detecting the processing stages of the head part and the tail part of an intermediate billet of hot-rolled strip steel in a production process of a hot rolling unit; and when it is detected that the head and the tail of the intermediate billet of the hot-rolled strip steel are located at the preset positions of the hot rolling unit, a preset rack of a finishing mill is controlled to machine the hot-rolled strip steel according to preset rolling parameters corresponding to the head and the tail of the hot-rolled strip steel at the preset positions. According to the embodiment of the invention, the problem of cooling wave shape in the production process of the hot-rolled strip steel is solved.

Description

technical field [0001] The application belongs to the technical field of hot-rolled steel strip production, and in particular relates to a shape control method, device and equipment in the production process of hot-rolled strip steel. Background technique [0002] In the production process of hot-rolled strip steel, due to the uneven stress distribution of the hot-rolled strip steel in the finishing mill and the unevenness of the laminar flow cooling temperature, edge waves appear after the hot-rolled strip steel is cooled by laminar flow; In particular, the head and tail of the hot-rolled strip steel are in a free state due to no tension effect, the edge waves are serious, and the plate shape is not controlled, which increases the difficulty of subsequent leveling, and the product is degraded or scrapped due to edge wave defects, and the yield rate of thin gauges is low. . [0003] In the prior art, when producing high-strength and thin-gauge steels, steel mills of the sam...
