Рассмотрена усовершенствованная технология выплавки марганцовистой стали марки 110Г13Л в дуговой сталеплавильной печи емкостью 25 т методом окисления. Рассмотрены все основные периоды ведения плавки. Представлены данные по исследованию шлакового режима процесса выплавки стали. Расчетным путем с применением практических данных по химическому составу шлаков окислительного и восстановительного периодов проведена оценка активности кислорода в металле. Графически показана зависимость активности кислорода в металле от суммарного содержания оксидов марганца и железа в шлаке. Кроме того, рассмотрена методика определения необходимого количества алюминия для раскисления металла с целью получения его требуемого количества в готовом металле. Исследовано влияние концентрации алюминия в металле на ударную вязкость марганцовистой стали.

The article describes the technology of 110G13L manganese steel smelting in an electric arc furnace with a capacity of 25 tons by oxidation method. All the major periods of melting have been reviewed, as well as the data on the study of the slag mode in the steelmaking process has been presented. By the calculating method with the use of practical data on the chemical composition of slag oxidation and reduction periods, the estimation of oxygen activity in metal has been carried out. The dependence of oxygen activity in metal on the total content of oxides of manganese and iron in the slag has been shown graphically. In addition, the determination technique of necessary aluminum amount for deoxidation of metal for the purpose of receiving the amounts required in the fi nished metal has been observed. The infl uence of the concentration of aluminum in the metal on impact strength of manganese steel has been studied.
