The influence of the chemical composition of slag melts on the degree of solubility of hydrogen and water vapor was simulated and models of the structure of slag and metal melts were developed, which were used to assess the influence of various options for placing impurity elements in melts on their charge state. The dissolution of water vapor falls on the region of slags with some excess oxygen, and the dissolution of hydrogen - on the region of slags with a deficiency of oxygen. In other words, the dissolution of water in slags occurs only under oxidizing conditions, and hydrogen - under reducing conditions. In light of the above, it is logical to assume that the dominant role of in multifactorial dependencies is a sign of hydrogen being in a relatively neutral state, an increase in the role of the parameter Δe indicates the intensification of its interaction with the surrounding atoms of the matrix, primarily oxygen.
