In allusion to the requirements of bearing steel for ultralow T[O], Ti, analyzing the effects of slag system to T[O] by FACTSAGE thermodynamic calculation. The calculation results shows that the slag system of bearing steel should be controlled in the area that SiO2 0%~20% Al2O3 25%~45% CaO 45%~65%,it is helpful to control T[O] the conclusion could be got by analyzing the control of T[O] and the content of Ti that control Als at 0.02% 0.08% is reasonable and basicity of slag need to be controlled at 5~8 in the smelting process of LF. Commerical test shows that in the bearing steel which was trial-produced TO] 15×10-6,N 60×10-6,[Ti] 30×10-6, and achieve batch production for ultralow oxygen bearing steel at last.
