ABSTRACT 
In this work, theoretical and experimental studies on the behavior of sulfur and 
phosphorus in a steelmaking bath were carried out, which made it possible to carry out 
complex studies on steel refining in ICF using slags under experimental industrial 
conditions. At the same time, by selecting special slags and reducing the height of the 
meniscus of the bath mirror, they provided an increased refining ability of the slag, 
which made it possible to keep it above the metal melt and reduce the “sliding” to the

crucible wall. The thermodynamic, kinetic and technological parameters of the metal 
refining process with the use of slag in the ICF are determined. Quantitative 
dependences of the main technological parameters of metal refining are obtained, which 
form the basis of a new technological instruction for steel production, reflecting the 
effect of temperature on the dephosphorization process and the duration of metal 
exposure under slag in the ICF on the final sulfur content in the metal.
