Abstract

The invention discloses an online precision evaluation method for a hot-rolled strip steel side press, and belongs to the technical field of steel rolling automatic control. The online precision evaluation method comprises the following steps: acquiring a set value and a measured value of a side press parameter; after the side press is put into use and the extrusion action is completed, calculating the value of each precision evaluation index based on the set value and the measured value of the parameters of the side press; on the basis of a preset scoring system, according to the values of the precision evaluation indexes, determining scores of the precision evaluation indexes, adding the scores of the precision evaluation indexes to acquire a comprehensive precision score of the side press; and when the obtained scoring result exceeds a normal range, giving an alarm prompt. Comprehensive evaluation is carried out from the aspects of an inlet pinch roll, an outlet pinch roll, hammer extrusion action, the transmission shaft action and the like, the operation precision and state of the side press can be judged in real time, and help is provided for timely eliminating equipment and production faults on a production site.

Description

Technical field [0001] The present invention relates to the field of automatic control technology of rolling, and more particularly to an online precision evaluation method of a hot-rolled strip steel side press. Background technique [0002] The thick rolled side press is located between the bullet box and the rough rolling, and since the slab width type is small, when the product target width is less than the slab width to reach a certain value, it is necessary to use a side blank width. Adjust to ensure product width quality. The side blade equipment mainly includes an inlet side guide, an inlet clamping roller, an outlet clamping roller, a hammer head, a drive shaft, aircraft roller, and the like. [0003] The research results of hot rolled steel side pressure machine control technology are as follows: Application No. CN107175260A, discloses a width control method based on a width-shaped biller of a fixed side press, proposed a fixed-width siderup The wedge-shaped width contr...
