在钢包中加入精炼渣可使钢包渣中Σ(FeO+MnO)≤264%,碱度平均提高121;钢包底吹氩参数控制在流量8～12Nh,吹氩时间大于5min时,可使钢水中T[O]含量平均降低2588%。
The addition of refined slag in the ladle can make Σ (FeO + MnO) ≤264% in the ladle slag and raise the alkalinity on average by 121. The parameter of argon blowing at the bottom of the ladle is controlled at the flow rate of 8 ~ 12Nh and the argon blowing time is more than 5min, The T [O] content in molten steel decreased by 2588% on average.
