The invention relates to the technical field of 
rare earth alloy, and provides an 
alloy technology of adding Ce into bearing steel for inhibiting formation of 
TiN compound inclusion. The 
alloy technology comprises the following steps: when a primary 
smelting furnace carries out steel tapping, making pre-smelted slags; in an LF (
Ladle Furnace) refining process, making refining slags; at the end stage of vacuum 
smelting, adding 
rare earth Ce of which the adding amount is 0.15-0.75kg / (
ton of steel); after the 
rare earth Ce is added, carrying out steel 
ladle bottom blowing Ar for soft stirring. According to the alloy technology, the rare earth Ce is added into bearing steel, MgAl2O4 in the steel is modified into a specific type of rare earth 
oxide (Ce2O3) or rare earth oxysulfide (Ce2O2S), andthe separation of the heterogeneous 
nucleation of 
TiN on MgAl2O4 in a solidification process is inhibited, the generated rare earth 
oxide or rare earth oxysulfide has a small size, and the 
hardness is far lower than that of MgAl2O4 inclusion. The obtained simple substance 
TiN inclusion has the advantages of small size and even distribution, and a new method is provided for improving the fatigue life of bearing steel.
