description: The topic of the final qualifying work: "Improving the system of preparation of liquid metal for the manufacture of steel casting."In electric arc furnaces there are favorable conditions for remelting high-alloyed waste. The peculiarity of steel smelting in electric arc furnaces is the ability to work with one slag, without a special recovery period. It is planned to use the 20GL steel grade according to the Russian Gost. All technical requirements for the melting shop are defined, the processes of the melting shop are described. A chain of preparation of liquid metal before pouring into molds has been developed, all charge, additive and alloying materials have been painted. A possible deviation from the chemical composition requirements for carbon, manganese, silicon, chromium, nickel was determined. The type of scrap allowed for use must comply with GOST 2787-75 (3A;5A;8A;9A; 10A). Further, the system of supply of alloying additives in the melting process was improved. For the final deoxidation of the metal and fine-tuning of its chemical composition, the purge station is connected to the supply system of alloying elements. After the chemical composition of the metal meets the specified, the smelting and quality control of the metal takes place.
