Zusammenfassung:The influence of steel casting on the defects of rolled products at OAO Magnitogorskii Metallurgicheskii Kombinat (MMK) is investigated. In particular, the influence of the slag-forming mixture used in the intermediate ladle and in the mold on defects of the cold-rolled sheet is studied. A new composition of the slagforming mixture employed in the mold reduces the rejection of cold-rolled sheet due to smelting defects.
