Abstract
The analysis of the conditions and performance indicators of the flexible modular furnace (FMF) is carried out. The effect of liquid pig iron consumption on the indicators of steelmaking in the FMF is shown. The problems in the effective use of liquid pig iron in steelmaking have been established. One of the main problems is the unstable composition and temperature of pig iron due to the lack of homogenizing equipment and the different duration of storage of pig iron in ladles. Another problem is that the pig iron is not completely drained from the ladle due to the overgrowth of the neck, which makes it difficult to make steel due to the lack of accurate information about the mass of pig iron. A set of measures has been developed to improve the efficiency of steel smelting as a result of stabilization of the temperature and chemical composition of liquid iron.
