The paper deals with the corrosion rate of refractories in glass melt under isothermic conditions. On the basis of theoretical analysis, experimental results and critical evaluation of published corrosion rates the authors have suggested more accurate forms of equations for the calculation of flow corrosion and of that at glass melt level in terms of glass melt viscosity and other conditions. The equations can be used with satisfactory accuracy also in the corrosion of operational, multicomponent refractories in technical glass melts.
