“…In order to study the influence of the quality of raw materials and technology on the structure of coke and its physical and mechanical properties under the conditions of ArcelorMittal Krivyi Rih, the qualitative indicators of the coal batch (moisture content, ash content, petrographic composition (according to ΣFC), bulk density, content of class 3-0 mm in batch) [14,23,29] were used to analyze the distribution of the coke by size classes and its mechanical strength.…”

“…Considerable change in granulometric composition of the coke is also seen in switching from a wet to dry slaking of the coke. Dry slaking significantly increases the content of the most valuable 40-60 mm class in the gross coke and reduces the content of the >80 mm class, which consists of the weakest coke [13,14].…”

The raw materials (coals different stages of metamorphism) and technological factors (period and temperature) of the coke-making that determine the carbon structure of blast furnace coke, and its physical and mechanical properties are analyzed. The change granulometric composition of the coke as a function of the coal batch properties is described in detail. The installation determines the possibility of influencing the carbon structure of coke, its granulometric composition in its production in order to increase the yields of the most valuable fractions, and improving its quality characteristics to achieve high-performance blast furnaces. Analysis of the results indicates that, with no changes in the coking conditions, the granulometric composition depends significantly on the ash content and packing density of the coal batch. Research has shown that the petrographic composition of the coal batch also affects the structure and size of the coke. The closest relationship is established between the magnitude of the fusinized components ΣFC and the output of the coke fractions 80–60 mm, 40–25 mm, and <25 mm. The method of mechanical treatment and stabilizing of blast furnace coke is proposed, which includes the improvement of the initial indexes of its quality M25, M10, and class >80 mm in continuous or periodically working open or closed industrial cylindrical oblique stabilizer drum.
