Technologies of non-furnace injection ladle desulfurization of cast iron are based on the introduction of reagent particles into liquid cast iron using high-speed gas jets. The patterns of behavior and interactions of two-phase jets (transport gas + reagent) with molten cast iron are complex, since the individual dynamic characteristics of an individual particle are lost. Also important is the question of the ratio of the number of particles that have gone deep into the metal and particles that have ended up in a floating bubble. In this work, to assess the factors and parameters of the immersion of a reagent particle in ladle desulfurization of cast iron, the aim of the work is formulated - to develop an approximate mathematical model in order to assess the immersion of reagent particles with gas into molten cast iron. The approximate mathematical model is developed taking into account the dynamic nature of the process, in which some of the values adopted correspond to higher speeds of movement.
