Problems solved by technology

However, the causes of surface longitudinal crack defects are complex, and relying solely on data analysis will to a certain extent ignore the impact of other quality events without parameter records, as well as the transmission of quality events between processes due to heredity and correlation effect

Embodiment Construction

[0019] The technical scheme of the present invention will be described in more detail below in conjunction with accompanying drawing:

[0020] The method of the present invention is based on a knowledge graph. Knowledge graph is essentially a semantic network, its nodes represent entities or concepts, and edges represent various semantic relationships between entities / concepts. Each model in the knowledge graph ontology is an abstract concept, and the entity nodes corresponding to the ontology model are the concrete representation of the ontology concept in reality.

[0021] The present invention adopts a top-down approach to construct the knowledge map for traceability and analysis of longitudinal crack defects on the surface of iron and steel products. Therefore, it is necessary to design and define the ontology model of the knowledge map and the relationship between the models. With the help of experts in related fields, the cross-process causes of longitudinal crack defec...

Abstract

The invention discloses a steel product surface longitudinal crack defect tracing and analyzing method based on a knowledge graph, and belongs to the technical field of steel product quality tracing. A route is constructed by adopting a top-down knowledge graph, knowledge carding is performed by means of industry experts in the aspect of steel product surface longitudinal crack defects, a steel product surface longitudinal crack defect traceability knowledge graph body is designed, in combination with actual data of enterprises,entities and relationships of the knowledge graph are created, and a cross-process steel product surface longitudinal crack defect tracing knowledge graph is constructed. The method has the advantages that the knowledge graph visualization technology is used for representing the transfer relation between the quality defects and the quality events of the whole process, the limitation of procedures is broken through, and cross-procedure tracing analysis of the longitudinal crack defects on the surface of the steel product is achieved.

Description

technical field [0001] The invention belongs to the technical field of iron and steel product quality traceability, and in particular relates to a method for traceability analysis of longitudinal crack defects on the surface of iron and steel products based on a knowledge map. [0002] technical background [0003] In the original traceability of surface longitudinal crack quality defects of iron and steel products, the entire production process of steel products with surface longitudinal crack quality defects must first be obtained through the association of specific fields in the relational database or the product ID, and then analyzed through the corresponding data. Cause traceability. Technicians need to have a clear understanding of the complex relationships among data sheets, the meaning and associated impact of each production parameter recorded in the data sheets. However, the causes of surface longitudinal crack defects are complex, and relying solely on data analys...
