| 摘 要： | 本文通过９０吨ＵＨＰ电炉氧化渣脱硫及影响钢包脱硫与ＬＦ脱氧，脱硫的工艺研究指出，为确保电炉钢的质量，稳定成分，满足连铸的要求，必须造好泡沫渣，限制电炉出钢时（Ｓ）（Ｐ），防止氧化渣进入钢包，加强原始钢液脱氧，强化ＬＦ炉脱氧与吹氩搅拌，保持ＬＦ炉良好的还原气氛与一定的白渣时间。

| Abstract: | This article points out through study of desulphurization with oxidizng slag in 90t UHP EAF and the process affecting desulphurization in ladle, deoxidation. desulphurization in LF furnace , in order to ensure quality of EAF melted steel, stabilize composition and meet requirement of continuous casting, it is necessary to make good foamy slag, limit S] P] content during tapping from EAF, prevent oxidizing slag from enter-ing ladle, strengthen deoxidation of original liquid steel,intensify deoxidation and stirring with argon in LF furnace, maintain good reducing atmosphere in LF furnace and a certain time for white slag. |
