 oxygen impact on the quality of bearing steel and its control
In steel wT. O = 10 by 10-4% than the fatigue life of bearing steel wT. O = 40 x 10-4% increase 10 times. WT. O = 5 x 10-4% of the fatigue life than wT. O = 40 x 10-4% to 30 times. Bearing steel production is the key to DNA.
That should be paid attention to the problems in the process of smelting
steel liquid in the early to implement low oxidation and low temperature;
reinforcement steel at the beginning of water beforehand DNA;
 using diffusion deoxidation of SiC and Al powder;
 refining, in the middle of the oxygen content in steel is reduced, decreases in the Al adopt the method of feeding Al line add Al;
to choose the appropriate refining slag system;
