%X The migration of Ti between Ti-containing slag and molten iron was found to be controlled by the diffusion of Ti ions in slag under the experimental conditions. The apparent order of reaction was detected to be of quasi-zero, and the apparent activation energy to be 258kJ/mol. The effects of some factors such as content of Ti in slag, basicity and temperature on the rate of migration have been also discussed. It seems that the basicity of slag serves a dual influence: to increase the basicity in slag with higher TiO_2 content may restrain from the reduction of Ti, while with lower TiO_2 content may accelerate the Ti reduction. Two distinguished regions of the restraint and acceleration of the reduction of Ti by Si may be drawn by wt-% ratio Si]/Ti] on the basis of thermodynamical analysis.
