An important problem in improving the slag mode of steelmaking in EAF is the substantiation of the rational component and chemical composition of fluxes that form the slag phase, the properties of which provide high performance and an energy-efficient mode of electric steelmaking. The kinetics of dissolution of lime in the slag of the oxidation period of steelmaking in EAF was studied by introducing a high-temperature furnace model (40 kg; LPZ-67 with periclase lining) onto the surface of the bath using limestone fractions of 3 and 10 mm with different degrees of firing.
