The addition of peptlzers and surfactants in optimal amounts makes it possible to reduce the moisture content of the suspensions by 10-15% and thereby to increase the efficiency of the technological process.One of the most important properties of the refractories used in the lining of metallurgical plants is wettability by molten metals and slags. Wetting in equilibrium conditions is characterized by an equilibrium wetting angle 8o [i, 2].The equilibrium wetting angles in the system of refractory--slag melt establish themselves slowly because of the multiformity of the processes involved (spreading, permeation, reciprocal diffusion, solution, etc.) and are near zero. A study of wetting in these systems therefore presents difficulties.
