| Abstract: | The function of ladle furnace (vacuum) at shanghai No.5 Steel Co.Ltd involve heating, vacuum degassing and argon bubbling. Adoption of more updated standards and advance of the primary and secondovry steelmaking processes have greatly lowered the oxygen content in the high carbon-chrome bearing steel from 25×10-6 to 8.97×10-6, which is in the advanced level in China. |
