Post-rolling rapid cooling method for online solid solution treatment of steel plate based on internet of thing

Abstract

The invention belongs to the technical field of cooling of steel plates and discloses a post-rolling rapid cooling method for online solid solution treatment of a steel plate based on the internet ofthings. A post-rolling rapid cooling system for the online solid solution treatment of the steel plate based on the internet of things includes an image acquisition module, a temperature detection module, an operation control module, a main control module, a wireless communication module, a server, a cooling module, a water spraying module, a cooling simulation control module, a defect detection module and a display module. A good simulation environment is provided for system tests, study of algorithm debugging, closed loop control and the like through the cooling simulation control module, the online debugging time is shortened, the production debugging cost is reduced, and online risks are greatly reduced; meanwhile, a detection mold is utilized to predict the type and location of defects through the defect detection module, and detection results can be more precise.

Description

technical field [0001] The invention belongs to the technical field of steel plate cooling, and in particular relates to an online solid-solution steel plate post-rolling rapid cooling method based on the Internet of Things. Background technique [0002] The steel plate is a flat steel material casted with molten steel and pressed after cooling; it is flat and rectangular, and can be directly rolled or cut from a wide steel strip; the steel plate is divided according to thickness, and the thin steel plate is <4mm 0.2 mm), medium-thick steel plate 4-60 mm, extra-thick steel plate 60-115 mm. Steel plates are divided into hot rolling and cold rolling according to rolling. The width of the thin plate is 500-1500 mm; the width of the thick plate is 600-3000 mm; the thin plate is divided into steel types, including ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel And industrial pure ...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the existing technology are: the existing on-line solid-solution of the steel plate after rolling has poor rapid cooling effect, the commissioning time and commissioning cost are large, and the large process improvement will also involve the change of the system structure. It brings risks to the commissioning of the production line, and may even bring certain losses; at the same time, the manual quality inspection method of steel plates relies on industry experts to visually observe photos in the production environment to give judgments; the detection accuracy is low
