Method and device for improving continuous casting flaw detection qualification rate

Abstract

The embodiment of the invention provides a method and device for improving the continuous casting flaw detection qualification rate. The method comprises the steps that obtained continuous casting billet image information is input into a training model, the training model is obtained through training of multiple sets of training data, and each set of training data in the multiple sets of trainingdata comprises the continuous casting billet image information, identification continuous casting billet center metallographic structure label information and preset inclusion index information; output information of the training model is obtained, and the output information comprises continuous casting billet center metallographic structure information and inclusion information corresponding to the continuous casting billet image information; according to the continuous casting billet center metallographic structure information and the inclusion information corresponding to the continuous casting billet image information, the continuous casting billet image information are screened and filtered to obtain standard continuous casting billet image information with qualified flaw detection, thereby achieving the technical effects of improving the flaw detection qualification rate of the continuous casting billet, reducing the inclusion content, ensuring the internal quality of the continuous casting billet and reducing the production cost.

Description

technical field [0001] The embodiments of this specification relate to the field of metallurgy technology, and in particular to a method and device for improving the qualified rate of continuous casting flaw detection. Background technique [0002] At present, the production cost of the iron and steel industry remains high, and the overall profit is not high, especially for medium and heavy plate enterprises, which are in a state of meager profit or loss. The pass rate of flaw detection is an important economic index of steel and steel enterprises with medium and thick plates. The pass rate of flaw detection directly determines the economic benefits, production costs and contract fulfillment rate of the enterprise. In the continuous casting production process of medium and heavy plate steel, element segregation, porosity and microcracks in the core of the steel plate are prone to occur, resulting in unqualified flaw detection of the steel plate after rolling. Therefore, it i...

Problems solved by technology

[0005] The embodiment of this specification provides a method and device for improving the pass rate of continuous casting flaw detection, which solves the problems in the prior art that large inclusions and microcracks are easy to appear in the continuous casting slab during the rolling process, and it is easy to aggravate the cracks in the center of the continuous casting slab. Segregation and banded structure lead to unqualified flaw detection, and the technical problem that the pass rate of flaw detection of continuous casting slabs cannot be quickly identified, so as to improve the pass rate of flaw detection of continuous casting slabs, reduce inclusion content, and ensure the internal quality of continuous casting slabs. The technical effect of reducing production costs
