The article presents a study of the influence of gas elements (oxygen, hydrogen and nitrogen) during metal processing with a mixture of gases (argon, nitrogen) on the macrostructure of the metal after cooling. One of the most common methods of ladle processing of steel is the process of blowing metal with inert gases and its vacuuming. A mathematical model has been developed that allows us to consider the process of gas removal and calculate the quantitative indicators of the removal of dissolved gases from the metal during its processing. Taking into account the thermodynamic and kinetic features of the dissolution of gases in the metal during blowing metal in the ladle with inert gases and during vacuuming allowed us to clarify the physicochemical processes of gas behavior in the metal, which will lead to the possibility of developing a new technology of ladle processing of metal using mixtures of inert gases.
