Abstract

The article presents structural changes of blast furnace coke. Mass proportions of the crystalline phase of coke before the blast furnace process and after heat treatment are presented. For this purpose, studies were carried out using the Seifert X-ray diffractometer. The crystallite dimensions were determined - width, height and interplanar distance. The crystallinity coefficients were calculated. The nanoporosity structure on the surface and inside the coke pieces was determined for selected samples. The structural tests were compared with coke test results after the processes under variable temperature conditions.

Keywords: Metallurgy, coke for blast furnace, SAXS method, structural tests, crystallinity of coke
