Effect of temperature gradient on capillary migration slag components in refractories

Conclusions On the assumption of capillary migration of particles due to the overflow of a sufficiently thin external contact layer, an equation is obtained for the velocity of droplets in immiscible liquids. In the temperature gradient field, the rate of separation of the segregating phases and the formation of the zones in the refractory is proportional to the temperature coefficient of the interphase tension, and is retarded with increase in the slag's viscosity. In contrast to previously known equations, we postulate an inverse relationship for the rate of displacement and the size of the separating droplet of segregating iron-manganese oxide melt.Translated from Ogneupory, No.5, pp. 15–19, May, 1992.
