In the process of casting rare earth steel, the rare earth oxides enter the melting layer of casting powder, which affects and limits the normal play for metallurgical properties of casting powder. In the paper, the effects of rare earth oxides on melting temperature, viscosity and crystallization temperature of mould flux with different basicities are systematically analyzed aiming at the problem. The results showed that a small amount of rare earth oxides could facilitate the melting of casting powder as well as the melting temperature, viscosity and crystallization temperature of casting powder with different basicities were changed significantly with the increase of rare earth oxides content.
