Results of a comprehensive study of the material composition and microstructure of 20 skull samples taken after blowing out AO EVRAZ NTMK blast furnace No. 6 are provided. More than 30 mineral and metal phases of different chemical classes are diagnosed in skull samples. Unlike the skull of blast furnaces of other metallurgical plants (NLMK, ZSMK), NTMK blast furnace skull has an abnormally high content of titanium, zinc, and vanadium compounds, as well as heavy non-ferrous metals and sulfur. On the basis of detailed petrographic analysis, five structural and genetic types (versions of composition and origin) of the skull are identified. Skull versions contain a large amount of grenal, which is dominated by refractory compounds of titanium and vanadium carbonitrides of the general formula (Ti, V)(C, N).

提供了对吹出AO EVRAZ NTMK 6号高炉后20个头骨样品的材料组成和微观结构进行综合研究的结果。在头骨样品中诊断出30多种不同化学类别的矿物和金属相。与其他冶金厂（NLMK，ZSMK）的高炉炉壳不同，NTMK高炉炉壳的钛，锌和钒化合物以及重有色金属和硫的含量异常高。在详细的岩石学分析的基础上，确定了头骨的五种结构和遗传类型（组成和起源的版本）。骷髅头版本包含大量的鹰嘴豆，其中以通式（Ti，V）（C，N）的钛和钒碳氮化物的难熔化合物为主。
