Complex sinter three-dimensional microscopic mineral phase analysis method based on feature fusion

Abstract

The invention discloses a complex sinter three-dimensional microscopic mineral phase analysis method based on feature fusion. The method comprises the steps of adopting an optical microscopic analysisand electron microscopic analysis fusion mode to distinguish the mineral phases difficult to distinguish under an optical microscope by using an electron microscope to thereby obtain a two-dimensional ore phase complete distinguishing graph of the complex sinter, performing three-dimensional reconstruction to obtain a three-dimensional microscopic ore phase graph of the complex sinter, and setting the opacity and further sectioning to obtain the ore phase perspective views and three-dimensional microscopic section views of the complex sinter. By means of the mode, each ore phase of the complex sinter can be accurately distinguished, the volume proportion of any ore phase or air hole can be more accurately obtained, the distribution characteristics of all the ore phases on different sections can be represented, and the overall structure and the combination state of all the ore phases and air holes in the complex sinter can be visually observed.

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
