1. 1

   CLO 1: At the end of the subject, the student has a deep knowledge of the entire metallurgical chain of iron and steel production (from the blast furnace process to the casting of steel). the student comparatively studies iron oxides and their reduction, cast iron production technologies, methods of melting steel in converter, marten and electric furnaces. the course covers methods of improving steel quality (vacuum, plasma, etc.) and liquid steel casting technologies (ingot, mold, continuous casting). the student also analyzes the processes of preventing defects in ingots and forming the structure. thus, the student is equipped with complete engineering knowledge for the technological management of ferrous metallurgical enterprises.
