Embodiment Construction

[0064] The embodiment of the present invention provides a method for controlling the finishing temperature of strip steel, which is used to solve or at least partly solve the technical problem of poor control effect in the existing method.

[0065] The general idea of ​​the technical solution in the embodiment of the application is as follows:

[0066] In the hot rolling process of strip steel, the steel type, specification and working condition of the strip steel are first obtained, and the control strategy is determined according to the steel type, the specification and the working condition, and then the control strategy corresponding to the control strategy is selected. A target function is preset, and an adjustment amount related to the finish rolling temperature is obtained according to the preset target function; then, based on the adjustment amount, the finish rolling temperature is controlled.

[0067] The above method, compared with the existing single control strate...

Abstract

The embodiment of the invention provides a strip steel finish rolling temperature control method. The method includes the steps that the steel type, specification and working conditions of strip steelare obtained; a control strategy is determined according to the steel type, specification and working conditions; a preset objective function corresponding to the control strategy is obtained; the adjusting amount relevant to the finish rolling temperature is obtained according to the preset objective function; and on the basis of the adjusting amount, the finish rolling temperature is controlled. By means of the method, the technical problem that in an existing method, the control effect is poor is solved.

Description

technical field [0001] The invention relates to the technical field of steel rolling, in particular to a method for controlling the finish rolling temperature of strip steel. Background technique [0002] In the hot rolling production process, the final rolling temperature affects the distribution of rolling force and load and the precision of the exit thickness of the finished strip, which is an important parameter affecting the performance of the strip. [0003] In the existing methods, the adjustment method based on speed or the adjustment method of cooling water between racks is generally adopted, but as the control standard of high-precision strip steel is getting higher and higher, and the production conditions of hot-rolled strip steel are complex and changeable, different The control performance required by the control system will be different under working conditions. At present, the single control method has problems such as poor stability and large temperature flu...
