[0006] Based on the problem that the determination of the mineral composition of sintered ore in the prior art mainly relies on manual operation, the workload is large, the efficiency is low, the recognition accuracy is easily affected by the subjective influence of the operator, and the mineral phases of complex sintered ore cannot be accurately distinguished. The present invention provides A method for establishing a non-structural information library of sinter with complex composition based on supplementary segmentation. This method can effectively characterize the microscopic information of sinter with complex composition, and accurately distinguish each mineral phase in sinter with complex composition. The multi-source information of sinter with complex composition has a very good effect in the performance research of sinter with complex composition

Abstract
The invention discloses a method for establishing a non-structural information library of complex sintered ore based on supplementary segmentation, which belongs to the technical field of sintered mineral phase analysis. multiples; splicing the captured pictures to obtain the complex sinter panorama of the light microscope and the electron microscope; performing classification threshold segmentation on the light microscope and the electron microscope panorama, and converting based on the corresponding relationship between the scales, so that the size of the light microscope and the electron microscope panorama are consistent; Add the mineral phases segmented under the electron microscope to the light microscope panorama to obtain a complex sinter panorama that is accurately segmented; use the precisely segmented panorama as a framework to establish a sinter non-structural information library based on a distributed file storage database to support sintering Multi-scale characterization of ore; the invention can not only effectively perform multi-scale information characterization of complex sintered ore, but also accurately distinguish each mineral phase, which is of great significance to the analysis and research of metallurgical properties of complex sintered ore.
Description
Technical field[0001]The present invention belongs to the field of sintering mineral phase analysis, and in particular, the present invention relates to a method of establishing a non-structural information base based on complex constituting complicated components.Background technique[0002]In recent years, China's steel industry has developed rapidly, and the small furnace of a large capacity of capacity has gradually been eliminated. In order to improve economic benefits, enhance competitiveness, start using a large-scale high furnace with a lower energy consumption, with blast furnaces, blast furnaces The quality requirements are also higher, and the sintering ore is the main raw material of the blast furnace. The quality of metallurgical performance has great influence on the obstacle, yield and coke ratios, and the type and structure of the sintered mine metallurgical properties. Closely related, such as low temperature reducing powder, strength, wear index, fuse performance, an...
