| description | The invention discloses a rare earth raw material for producing a functional refractory material for steelmaking and a preparation method of the rare earth raw material. The provided preparation method of the rare earth raw material comprises the following steps: 1) mixing rare earth powder with the purity of more than or equal to 99.0% and aluminum powder with the purity of more than or equal to 99.0% according to the molar ratio of rare earth to Al of (0.5-3): 1 to obtain an intermediate; and (2) sintering the intermediate obtained in the step (1) at the temperature of between 1,500 and 1,700 DEG C for 3.5 to 4.5 hours. The functional refractory material prepared from the rare earth raw material provided by the invention can effectively avoid the reaction of rare earth in molten steel with magnesium, high-alumina, silicate refractory materials and the like, so that pouring interruption or production accidents can be effectively avoided.
