Distinguish, obtain the complete 2D ore phase diagram of the complex sinter, and then perform 3D reconstruction to obtain the 3D microscopic ore phase map of the complex sinter, and obtain the perspective view of each mineral phase of the complex sinter by setting opacity and further cutting and three-dimensional microscopic cross-sectional view; through the above method, the present invention can accurately distinguish each mineral phase of complex sintered ore, obtain the volume ratio of any mineral phase or pore more accurately, and can characterize each mineral phase on different sections Distribution characteristics, visually observe the overall structure and combination state of each mineral phase and pores in the complex sinter.

Description

technical field [0001] The invention relates to the field of mineral phase analysis of complex sintered ore, in particular to a three-dimensional microscopic mineral phase analysis method of complex sintered ore based on feature fusion. Background technique [0002] Sintered ore is an artificial rich ore that is mixed with various materials and partially melted at high temperature. The internal mineral structure is very complicated. It is one of the main raw materials for blast furnace ironmaking. , wear resistance index and droplet performance, etc., will directly affect the blast furnace production; and the performance of sinter is closely related to the type and content of the internal mineral phase. At the same time, with the rapid development of my country's iron and steel enterprises, the shortage of high-grade iron ore resources has become increasingly prominent. In order to reduce production costs and enhance corporate competitiveness, a large number of low-grade iro...

Problems solved by technology

[0005] Based on the existing problems in the prior art of using optical microscope or electron microscope alone to obtain two-dimensional images to analyze sinter mineral phases, it is impossible to accurately distinguish mineral phases with similar gray scales and to intuitively express the internal structure of sinter, etc., the present invention A 3D microscopic analysis method of complex sinter mineral phases based on feature fusion is provided. Through the fusion of optical microanalysis and electron microscopic analysis, the mineral phases that cannot be distinguished under the optical microscope are distinguished by the electron microscope, and the obtained The 2D mineral phases of complex sinters are completely distinguished, and then 3D reconstruction is performed to obtain the 3D microscopic mineral phases of complex sinters, and the perspective view and 3D display of each mineral phases of complex sinters are obtained by setting opacity and further sectioning. Micro-sectional view, so as to accurately distinguish each mineral phase of complex sinter, obtain the volume ratio of any mineral phase or pores more accurately, and can characterize the distribution characteristics of each mineral phase on different sections, and visually observe each mineral phase The overall structure and bonding state of pores and pores in the complex sinter
