The work is devoted to mathematical description of slag foaming process in a metallurgical convertor and determination of an optimal gas volume for blowing and to avoid overflow of convertor. Oxygen convertors are widely used in steelmaking process. Inside convertor the foam increases its depth and can overflow the convertor, which is an unwanted situation with dangerous consequences. Presented mathematical model includes equations of molten slag impulse conservation and volumetric part of gas in it, which allows to estimate foaming speed depending on blowing intensity For conducting of numeric experiments it is proposed to make discretization of differential equations using the central difference method, and to implement the mathematical model in computer program using a widespread programming language C#.
