Description

Background
In the process of processing and producing steel, steel plate cooling is a treatment process for cooling hot rolled steel plates in a steel mill on line, the process simplifies the process flow, reduces the process cost, improves the quality of the steel plates and is widely applied. However, because the speed of the roller of the rolling mill is inconsistent when rolling the steel plate and the temperature generated in the cooling process is uneven, the head and tail temperature of the steel plate is lower than that of the middle part, and the head and tail temperature of the steel plate is lower, so that the performance detection and judgment of low alloy series steel plates, ship plates, construction steel, mechanical steel, pipeline steel, container steel and other steel types are greatly influenced. The steel plate has certain upper and lower limit control on yield strength and tensile strength, so that the yield strength and the tensile strength are kept in a certain range. And the sampling of the head and the tail occupies a large proportion in the performance detection process, when the temperature difference between the head, the middle and the tail is large, the yield strength and the tensile strength detected by the head and the tail are higher than those of the middle part by dozens of megapascals, even hundreds of megapascals, and the steel plate can be treated as an unqualified product, thereby influencing the production.
Aiming at the problem of head-tail temperature difference, head-tail shielding is mainly adopted to control the head-tail temperature difference, the shielding coefficient and the shielding distance are adjusted by detecting the head-tail temperature and the temperature distribution trend of the steel plate, if the water flow is controlled by accurately starting the water flow shielding function when the head-tail part of the steel plate enters a spraying area, a detection instrument needs to be installed in the spraying area, and at the moment, the instrument cannot complete the measurement work because the measured environment has too much shielding and interference. The traditional steel mill detection position mode, namely thermal detection, is a fully-called hot metal detector and is generally installed in a place without interference, so that in the actual production process, after a steel plate enters a cooling area, due to the fact that the environment in the cooling area is severe, the steel plate slips, roller way speed handover, roller way abrasion and other factors interfere, the detection precision of various detection devices cannot well achieve the preset effect; for example, the measured linear speed of the driving roller and the actual linear speed of the steel plate can have errors due to slipping, in-place detection of the roller conveying steel plate cannot be accurately triggered, the positions of the head and the tail of the measured steel plate are inaccurate, shielding control of the head and the tail low-temperature regions of the steel plate cannot be normally completed, longitudinal cooling uniformity of the steel plate cannot be guaranteed, even negative effects caused by inaccurate tracking can be caused sometimes, further performance instability is caused, and the production requirements cannot be met.
