Basing on thermo-simulation in laboratory, experimental study was accomplished to analyze the function mechanism of foaming agent and the foaming influence of its decompound production. The results indicated: function of foaming agents was due to their decompound and inter-reaction at high temperature. And some decompound production of foaming agent can reinforce the foaming ability of refining slag.

The influence of high temperature and high pressure on foaming agent's properties in opened and closed system, and influence of the change of foaming agent's properties on foaming capacity and foam stabilizing capacity are also studied. The multiple regression theory is used to establish the quantitative characteristic functions of foaming agent versus temperature and pressure. Based on the Gibbs Principle, the quantitative characterization is carried out on relation of foam system's free energy versus its surface tension, surface area and concentration, and the analysis of energy concluded that the disintegration of the foam is inconvertible. At the same time, the influence of change of foam's shape and structure on distribution of reservoir temperature and pressure is qualitatively described, and the coupling mechanism between temperature field, pressure field and chemical field is systematically expounded.

The cell structure refining mechanism shows that adding Mg decreases the surface tension of the aluminum alloy melt and hence to increase the bubble stabilization. Adding nuclear forming agent increases the nuclei of heterogeneous nucleation. Adding pre-heating foaming agent postpones its decomposition, hence to increase the uniform of foaming agent dispersion. Stirring within the middle stage of foaming agent rapid decomposition breaks up big bobbles to fine bobbles, hence to reduce mean cell diameter.
