| 摘 要： | 通过ＣａＯ－Ｂａｏ－ＣａＦ＿２－ＣａＣｌ＿２渣和Ｆｅ－Ｃｒ－Ｃ－Ｐ熔体间的分配平衡实验，研究磷、铬在该渣中的行为。结果表明，在一定范围内，增加渣中的ＢａＯ和ＣａＣｌ＿２含量，磷酸盐容量增加，铬酸盐容量的变化则较小。根据实验结果的综合分析说明，该渣对ｆＥ－Ｃｒ熔体具有较理想的脱磷保铬能力。在此基础上，在实验室内用该渣对含铬３０％的Ｆｅ－Ｃｒ合金进行了氧化脱磷的应用性试验，试验结果表明，适当的低温和ＢａＯ和Ｆｅ＿２Ｏ＿３添加量可获得大于５０％的脱磷率，铬几乎无烧损。

| Abstract: | Experiments on Cr,P distribution between CaO-BaO-CaF_2-CaCl_2 slagsand Fe-Cr-C-P melts are carriedout.The obtained results show that phosphate ca-pacity increases with CaCl_2 and BaO content in slag and chromite capacity has no ap-parent variation,and that this slag has stronger ability to dephosphorize without re-markable Cr losses,Based on the above work,the applied experiments of dephospho-rization for Fe-Cr melts containing 30%Cr with these slags are performed in thelaboratory scale. More than 50%dephosphorization efficiency and almost no Cr lossare achieved at the lower temperature,proper Fe_2O_3 amount and higher BaO contentin slag. |
