The article describes the practical experience of the foreign asset of the PJSC “Magnitogorsk Iron and Steel Works” - MMK Metalurji, consisting of a “hot” stage (casting and rolling complex (CRC) and a “cold” stage (cold rolling shop, hot-dip galvanizing unit, polymer coating line, metal service center) located at the production site in Iskanderun (Turkey). A brief technical description is given and the main parameters of the units used for the production of continuously cast slabs in the casting and rolling complex are given — an electric arc furnace (EAF), a ladle furnace (LF), a steel degassing unit (SDU) and a continuous casting machine (CCM), as well as advantages and disadvantages of the used concept of mini-mills. Two periods of CRC operation are described: during the starting and mastering of new units and technology (2011–2012), and from July 2021, when the complex was re-commissioned after a long period of conservation. The last part of the article indicates the actual parameters achieved for the period June-September in terms of chemical composition, assortment, standard sizes and productivity. Additionally, information is presented on the content of harmful elements and gas saturation of steel, as well as an assessment of the evolution of macrostructure defects on templates.
