Embodiment approach

[0098] The minimum thickness, maximum thickness, minimum width and maximum width of the current rolled strip are obtained from the PDI data through the production management system and sent to the process control system, and the process control system receives the minimum thickness, maximum thickness, When the minimum width and maximum width are used, the process control system determines the minimum width of the current rolling strip from the N steel identifications according to the corresponding relationship between the M group of strip properties and the N steel identifications in the fault valve configuration file. The first steel grade identification whose thickness, maximum thickness, minimum width and maximum width match at the same time is filled by the process control system into the corresponding message structure and sent to the basic automation system. The mode code identification corresponding to the first steel type identification is matched by the basic automatio...

Abstract

The invention discloses a laminar cooling control method and device and relates to the technical field of hot rolling. The method includes the steps that strip steel attribute information of currently-rolled strip steel is obtained; and a first fault valve setting mode matched with the strip steel attribute information of the currently-rolled strip steel is determined from N fault valve setting modules according to the corresponding relation between M sets of strip steel attributes and the N fault valve setting modes, wherein each of the N fault valve setting modes represents the fault valve starting configuration for all fault valves on K sets of headers, and the fault valves on the K sets of headers are correspondingly arranged according to the fault valve starting configuration instructed by the first fault valve setting mode. By means of the laminar cooling control method and device, the technical problem that the cooling temperature of a hot rolling strip steel production field fluctuates in the prior art is solved, it is ensured that the laminar cooling control temperature is more accurate and control is more punctual, and therefore the coiling temperature control precision is improved, and the quality of finished products is more stable.

Description

technical field [0001] The invention relates to the technical field of hot rolling, in particular to a laminar flow cooling control method and device. Background technique [0002] In the production process of hot-rolled strip steel, it is necessary to use a laminar flow cooling device to cool the strip steel after rolling and before coiling. The ideal metallographic structure and mechanical properties can be obtained by controlling the coiling temperature and cooling rate of the strip steel. The interlayer cooling zone is defined from the pyrometer at the finish rolling exit to the pyrometer at the entrance of the underground coiler. The layer cooling area is divided into a rough cooling area and a fine cooling area. Among them, the 1-18th set of headers is the rough cooling area, and the 19th and 20th sets of headers are the fine cooling area. [0003] In the existing technology, the failure valves are manually set in the work area according to the issued steel specifica...
