Problems solved by technology

At present, the porosity detection of metallurgical coke and foundry coke only has the method of pumping and draining water and calculating the true and false density. Through these methods, only the apparent porosity or total porosity of coke can be obtained, and the specific coke pores and coke wall cannot be obtained. Construction parameters such as diameter, thickness and distribution
However, using the optical microscope eyepiece ruler, although the distribution parameters can be obtained by manual row-by-row measurement, there are a series of shortcomings such as long time-consuming, high eye intensity, unrepresentative single-block detection, and poor reproducibility, which cannot be implemented in practice.

Embodiment 1

[0028] A front peak identification technology method for coke pore structure detection, including the following steps:

[0029] Step 1: Cut the irregular coke block into neat squares. The length of the coke block is 40mm, the width of the coke block is 40mm, and the height of the coke block is 20mm. Then the coke block is reinforced with a binder and then Fine grinding until the surface is bright;

Abstract

The invention discloses a prepeak identification technical method for detecting the pore structure of a coke. The prepeak identification technical method comprises the following steps: firstly, slicing the coke, and then putting the coke under a microscope to shoot; inputting a microstructure picture into a computer, marking all grayscale data values on a coordinate map according to the sizes by the computer; carrying out smooth processing on the coordinate map by the computer to obtain a peak, namely prepeak formed pores with lower value domain in a smooth graph; finding out a gray value corresponding to a position where a maximum gray value is located in prepeak distribution by the computer, and marking the gray value as a prepeak boundary valve; after the prepeak boundary valve is obtained, calculating out a pore wall segmentation boundary valve according to a formula that the pore wall segmentation boundary valve is equal to the prepeak boundary valve plus a deviation value; differentiating all pixel blocks into two types according to the pore wall segmentation boundary valve, namely pores and coke walls; continuously counting the size of each pore or coke wall in each line ofpixels on the picture and recording the size by the computer. The prepeak identification technical method disclosed by the invention can realize rapid accurate automatic identification of the coke pores and the coke walls, is high in detection speed and is convenient to use.

Description

Technical field [0001] The invention belongs to the field of coke detection, and specifically is a front peak identification technical method for coke pore structure detection. Background technique [0002] The strength of coke depends to a certain extent on its pore structure. At present, the porosity detection of metallurgical coke and foundry coke only has the methods of pumping drainage and true and false density estimation. Through these methods, only the apparent porosity or total porosity of coke can be obtained, and the specific coke pores and coke wall cannot be obtained Structural parameters such as diameter, thickness and distribution.
