The aim of the study described in this paper is to determine the character of deposits formed on the inner wall of an submerge entry nozzle during the continuous casting of steel. By using X‐ray diffraction and optic microscopy with refracted light, it has been found that the minerals most abundant in the deposit's structure are corundum, hibonite‐5H, hematite, graphite and, in certain cases, there is also magnetite. The results of the examination of the mineralogical composition and of the structure of the SEN wall after the exploitation in the continuous steel casting process are also shown.
