Problems solved by technology

[0003] Researchers at home and abroad generally use a single microscopic image to analyze the microstructure of coke. Ordinary optical microscopes do not have the function of automatic stitching, and the observation field of view is limited, so it is difficult to fully reflect the structural information of coke. The workload is very heavy, and the price of microscopes with automatic stitching function on the market is relatively high

Embodiment 1

[0055] 1) The chemical composition of the coke used in this example is shown in Table 1. The sample is roughly ground, hot-mounted, polished, dried, and observed under a microscope.

[0056] Table 1 The chemical composition of the coke used in the experiment

[0057]

[0058] 2) Image acquisition of the panorama: use a low magnification (40×) optical microscope to capture image information with a camera. Fix the sample, choose to start from the upper left corner of the sample to take the first shot, then make 2 unidirectional movements in the X direction, and take a shot after each movement. Then the microscope moves to the first shooting area, performs one unidirectional movement in the Y direction and takes pictures, and then performs two unidirectional movements in the X direction, and takes pictures after each movement. Repeat for a second one-way move in the Y direction and shoot, then do 2 one-way moves in the X direction and shoot after each move. Store all the pi...

Abstract

The present invention belongs to the coke microscopic structure analysis technology field, in particular to a coke microscopic structure analysis method based on a microscopic-level panoramagram. The method comprises the following steps of S10 shooting the surface of a coke sample to obtain a low-power electronic picture set; S20 using a median filtering method to smooth the digital photographs; S30 splicing and fusing the low-power electronic picture set to obtain a microscopic-level panoramagram; S40 appointing the local amplification areas based on the microscopic-level panoramagram, shooting the surfaces of the local amplification areas to obtain high-power electronic picture sets; S50 using the median filtering method to smooth the digital photographs; S60 splicing and fusing the high-power electronic picture sets to obtain the microscopic-level local amplification pictures; S70 linking the microscopic-level local amplification pictures and the local amplification areas. The method provides a path for analyzing the coke microscopic structure comprehensively and deeply, and provides the bases for searching a mineralization mechanism and a solution method and improving the coke product and the quality.

Description

technical field [0001] The invention belongs to the technical field of coke microstructure analysis, and in particular relates to a coke microstructure analysis method based on a microscopic panorama. Background technique [0002] The reaction mechanism of coke in the blast furnace will directly affect the thermal state and antegrade degree of the blast furnace, thus having a very important impact on the technical and economic indicators of the blast furnace. At the same time, coke, as an energy source, skeleton, and reducing agent, has an important impact on all links in the blast furnace. Therefore, by understanding the internal structure and pore distribution of coke, the performance of coke can be greatly improved, thereby reducing costs. The optical microstructure of coke is of great significance, which is conducive to saving energy, reducing economic costs, and reducing environmental pollution. [0003] Researchers at home and abroad generally use a single microscopi...
