Abstract

The invention belongs to the technical field of steel hot rolling, and provides a method and device for controlling the width of steel plates and strips and terminal equipment. The method includes thesteps that firstly, component information and a preset width value of the to-be-measured steel plates and strips and the exit temperature of a finishing mill are acquired; a temperature-width compensation curve corresponding to the component information is acquired according to the component information and a width compensation data set of the to-be-measured steel plates and strips; the width compensation value of the to-be-measured steel plates and strips is obtained according to the exit temperature and the temperature-width compensation curve corresponding to the component information; andthe width value of the to-be-measured steel plates and strips at the exit temperature is determined according to the width compensation value and the preset width value of the to-be-measured steel plates and strips. The temperature-width compensation curve corresponding to the component information is obtained by acquiring the component information of the to-be-measured steel plates and strips, thus, the width value of the steel plates and strips at the exit temperature is obtained, the width deviation, caused by the temperature change of the steel plates and strips, to steel plate and stripfinished products is avoided, and the yield of the steel plates and strips is increased.

Description

technical field [0001] The invention belongs to the technical field of steel hot rolling, and in particular relates to a method, device and terminal equipment for controlling the width of strip steel. Background technique [0002] The finished width accuracy of hot-rolled strip steel is a very important technical index. For hot-rolled production, the quality of width accuracy directly affects the yield of strip steel; for downstream users, it directly affects the raw material utilization rate. Every time the width deviation is reduced by 1 mm, the yield can be increased by about 0.1% based on the actual finished strip width. Therefore, high-precision width control technology can significantly improve economic benefits. [0003] The traditional method of controlling the width of the strip is usually to install a width measuring instrument at the exit of the finishing mill to control the width of the strip to the desired width by detecting the width of the strip at the exit o...
