The author analyzed total oxygen content, nitrogen content in steel made by typical process and the inclusion composition, change rule, morphology and distribution qualitatively and quantitatively by image analyzer, big sample electrolysis, SEM and energy spectrum analysis. The results showed that final inclusion form was small granule MnS, calcium aluminate, a small quantity of silicate and lumpy Al2O3. By intensifying deoxidation alloying process control in converter, argon blowing and slagging control and desulphuration and calcium reduction operation in refining course and overall-protection casting, the oxygen content was reduced by 20% above averagely, nitrogen content was reduced by about 10% and the inclusion content was reduced by 30%.
