Diagrams of changes in the parameters of two-phase flows and their components in the in-zone zone are obtained. The dependences of the depth of introduction of the reagent particles on the particle diameter and velocity are established. Activation of metabolic processes with the use of powdered calcium oxide due to the introduction of Al, Na2CO3 and natural gas into the refining system is substantiated. values (up to 0.001%). The most rational mechanisms for the effective interaction of the reagent introduced into the molten iron and sulfur are formulated. Calculation and theoretical predictions and recommendations are confirmed in experimental and industrial processing of cast iron by injection of both magnesium and calcium oxide. It is shown that at injection of granular magnesium on the optimized modes the degree of its assimilation reaches 96%, and at injection of lime with activation of process by additives, the degree of desulfurization of pig-iron increases in 1,5-2,0 times.
