On the quality control of coke
Thread Content
Through the dissection of laboratory blast furnaces, the relationship between the degree of coke dissolution in different areas and the changes in the optical structure of the coke was studied, in order to determine the optimal optical structure for coke. By coking with a single coal type and coking with blended coals, the relationship between the optical structure of coke produced from a single coal type and that of coke produced from blended coals, as well as the relationship between the properties of a single coal type and the optical structure of the resulting coke, can be determined; thereby establishing a correspondence between the properties of a single coal type and the optical structure of coke produced from blended coals. By combining these two steps, can the goal of controlling coke quality be achieved? :lol
There is always a gap between theory and practice; theory can only serve as a guide, not as a conclusion for production.
The factors affecting coke quality include the type of coal and coal blending specifications, as well as the heating regime during coking. These two elements need to be combined in order to obtain coke of good quality. Of course, the quality of the coal used is directly related to the quality of the coke. The method you use can basically achieve the goal. Furthermore, it is advisable to increase the bulk density of the coal to obtain coke of better quality.
