Problems solved by technology

However, for coke, which is composed of countless graphite crystallites through disorderly accumulation, there is no method for quantitative analysis and determination of its microcrystalline structure, which makes it difficult to obtain substantial explanations for the performance of coke in industrial production applications. sexual progress

Embodiment Construction

[0018] The following steps are for quantitative analysis of coke microcrystalline units on the HRTEM image of Liulin coal coke samples:

[0019] 1. Streak calibration and numbering, use graphics software to calibrate and number each stripe in the figure, see Figure 1.

[0020] 2. Determine the judgment parameters of each stripe. The area A of the stripe can be determined by counting the number of pixels in each stripe. The stripes in Figure 1 are single-pixel "thick", and the calculation of the area A is determined by the number of pixels. Therefore, this area is actually the length L of the stripes, and the length L is calculated by the following formula,

[0021] L(nm)=30(1 / nm)×A(nm 2 )

[0022] 30 is the sizing factor in this embodiment.

[0023] By fitting an ellipse to the stripe, determine the center of the ellipse, approximate it to the stripe's location coordinates (x, y), and the major axis r a and minor axis r b , and the inclination angle θ of the...

Abstract

The invention discloses a method to analyze coke microcrystal unit from high resolution transmission electric microscope image of coke. It includes the following steps: taking identification numbering to each stripe, measuring parameters; taking grouping to all stripe, calculating size, height, and interlayer distance of every stripe, calculating the ratio of each stripe occupying the image to gain the distribution condition. The invention could realize analysis for coke from microscope angle.

Description

(1) Technical field [0001] The invention relates to a method for quantitatively analyzing coke microcrystal units from a high-resolution transmission electron microscope image of coke, and belongs to the technical field of charcoal phases applied in coking. (2) Background technology [0002] Coke is widely used in the metallurgical industry, especially in blast furnace ironmaking, and the microstructure of coke has been regarded as one of the key research objects in this field. It has been proved that the main element constituting coke is carbon, which mainly exists in the form of graphite crystals in coke, but the scale of this graphite crystal is very small, only a few nanometers, and countless tiny graphite crystals of different sizes are disorderly. Stacked together make up the main component of coke. [0003] The images of graphite crystallites in coke can be obtained directly by using high-resolution transmission electron microscopy (HRTEM). The image of graphite crys...
