摘要: 在实验室条件下,采用Fe₂O₃-CaO-CaF₂和Na₂CO₃-Na₂SO₄渣系研究了在铁水预处理过程中熔体氧势的变化规律,寻求有利于同时脱磷脱硫的铁水氧势范围。结果表明,脱磷过程中熔体氧位在5min内迅速上升到5.911×10^-6~10.03×10^-6,5min后氧位在很小的范围内波动;在1623K温度下的铁水预处理过程中,控制熔体氧势范围为3.0×10^-6~6.5×10^-6,可获得终点磷含量为0.008%~0.012%的脱磷效果,同时铁水中的硫能降到0.003%~0.007%的水平。

Abstract: The changing law of oxygen potential was studied during hot metal pretreatment by using Fe₂O₃-CaO-CaF₂ and Na₂CO₃-Na₂SO₄ fluxes under the laboratory conditions. At the same time, the suitable range of oxygen potential for removing phosphorus and sulfur simultaneously was discussed. The results show that the oxygen potential in iron melt during dephosphorization can be reached to 5.911×10^-6~10.03×10^-6 in 5 min and then changes only in a narrow range. The final [P] content of 0.008%~0.012% and sulphur content of 0.003%~0.007% can be obtained at 1 623 K if the oxygen potential is controlled in the range 3.0×10^-6~6.5×10^-6.
