Abstract

The invention provides a prediction method and device for continuous casting center segregation. The method comprise: obtaining continuous casting billet image information, and inputting the continuous casting billet image information into a training model, wherein the training model is obtained by training multiple sets of training data, and each set of training data comprises the continuous casting billet image information and a label for recognizing billet process information on the continuous casting billet image information; obtaining output information of the training model, wherein theoutput information comprises billet process information corresponding to the continuous casting billet image information; and according to the billet process information corresponding to the continuous casting billet image information and the standard continuous casting billet process threshold, obtaining billet prediction information, and predicting whether the billet corresponding to the continuous casting billet image is subjected to center segregation. The technical problems that in the prior art, a casual inspection mode is adopted, judgment cannot be conducted one by one, and center segregation of continuous casting billets cannot be predicted in advance are solved. The technical effects that intelligent data processing is conducted on all steel billets in the continuous casting equipment, the risk of center segregation is predicted in time, the accuracy is high, and the quality of the steel billets is improved are achieved.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a method and a device for predicting center segregation in continuous casting. Background technique [0002] The central segregation of continuous casting billet refers to the uneven distribution of solute elements such as C, Mn, P and S in the central area of ​​the billet. On the longitudinal section of the slab, there are apparent forms such as V-shaped segregation, U-shaped segregation, point segregation, linear segregation and shrinkage cavities, and the solute elements fluctuate approximately periodically along the center line. Usually, the segregation in the center of the continuous casting billet is not enough to affect the quality of the final product, and it is allowed to exist. However, in the case of some steel grades such as hard wires with high carbon content, steel cord steel grades, and hydrogen-induced cracking resistant pipeline steel grades sensi...
