An adaptive and high-precision method for extracting rolling stock profile based on continuous rolling simulation

Abstract

The invention relates to a technology for extracting and self-adaptively correcting the profile of a rolled piece in the simulation process of full continuous rolling of profiles. The invention solves the problems of inaccurate contour extraction and inaccurate pass type caused by tapping bending and torsion in the current full continuous rolling simulation process of profiles, and proposes an adaptive and high-precision extraction of rolled piece contour based on continuous rolling simulation The main points of the technical scheme are as follows: take the middle section of the pre-rolled piece as the extracted section after rolling, track the rolling progress of the section, determine the extraction range of the section, and then extract the section within the extraction range The corresponding steel profile is subjected to bending profile correction and / or torsion profile correction. The beneficial effect of the present invention is: use the middle section of the pre-rolling piece as the extraction section after rolling, track the rolling process of the section, and correct the outline of the tapping within the determined section extraction range, which is suitable for steel rolling simulation.

Description

technical field [0001] The invention relates to a steel rolling technology, in particular to a technology for extracting and self-adaptively correcting the outline of a rolled piece in the simulation process of full continuous rolling of profiles. Background technique [0002] At present, the finite element method is used to simulate profile rolling. For single-pass simulation, the reliability and accuracy of the simulation are determined by the modeling and simulation setting conditions. Contour extraction, and in the process of semi-manual contour extraction, the accuracy must be judged by the naked eye through the pre-processing software, and at the same time, corresponding spatial position adjustments must be made to the extracted parts. Although the workload is large and the accuracy is low, it can at least meet the manual connection Rolling simulation needs. [0003] However, the semi-manual contour extraction is only suitable for the traditional manual full-range sim...
