This article is devoted to the research of the non-metallic inclusions of the E90KhAF rail steel in different zones of continuous cast billets. It is established that in the rim zone the main non-metallic inclusions are silicates of iron and alumosilicates. Alumosilicates and silicates of iron are identified in the zone of columnar crystals. Sulfides of manganese (MnS), silicates of manganese, aluminum and iron are found in the central zone of the billet.
