| 摘 要： | 工业生产条件下研究了含Ｎａ２ＣＯ３渣对电炉返回吹氧法冶炼不锈钢１Ｃｒ１２Ｍｏ脱磷的影响。结果表明：试验工艺在Ｎａ２ＣＯ３加入量为每吨钢１５ｋｇ的条件下，与常规工艺相比较，成品钢中磷含量平均降低０．００５％以上，取得明显的脱磷效果；同时金属炉料中磷含量控制范围放宽在０．００３％以下，方便了配料，降低了炼钢成本。

| Abstract: | The effects of Na 2CO 3 containing slag on dephosphorization of the stainless steel 1Cr12Mo refined by post O 2 blowing in EAF have been studied in industrial scale experiments.Results show that prominent results of dephosphorization are achieved and P content in the finish steel products is reduced by 0.005% on an average under the process condition of 15kg Na 2CO 3 addition/ton steel in comparison with the normal operating process. In the mean while the control range of P content in the metal charge is widened to 0.030% and it is thus of great benefit to the charge make-up and cost reduction for steelmaking. |
