| Abstract: | The cleanliness has an important influence on various mechanical properties of the wheel steel . The paper analyzes the cleanliness controlling technology in every smelting process such as 120 t BOF-LF-VD-round bloom continuous caster. Via practice application, perfect effect was obtained. The total oxygen contents have descended about 51.7% in LF process. The average value of total oxygen content in the round bloom is 15.3× 10^- 6 and casting structure is uniform. |
