摘要

摘要: 在高溫鉬絲爐內向鐵液中加入SiMg合金、Al及復合添加這兩種脫氧劑進行脫氧,并改變其添加順序,分析過程樣中溶解氧、全氧、殘鎂量及夾雜物隨時間的變化.結果表明:1873K時,鐵液中復合添加0.02%(質量分數)的SiMg和0.03%(質量分數)的Al脫氧,其脫氧程度與只用0.05%的SiMg脫氧相當,而鎂的收得率得到提高.SiMg/Al處理的試樣中夾雜物數量隨時間的變化與只用SiMg處理時一致,而Al/SiMg處理的試樣中夾雜物數量隨時間的變化與只用Al處理時一致.

Abstract: The deoxidation experiments of liquid iron were carried out in the high temperature molybdenum wire furnace by adding SiMg alloy, Al and combination of both. At the same time, the additional sequence of SiMg and Al was changed in the experiments. The contents of dissolved and total oxygen and residual magnesium were measured and change of inclusions in molten iron over time was investigated. The results indicate that the limit of deoxidization by the combination of 0.02% (mass fraction) SiMg and 0.03% (mass fraction) Al is comparable with 0.05wt% SiMg only and the yield of Mg in the molten iron treated by the combination is improved greatly at 1 873 K. In the case of SiMg/Al deoxidation, the change of inclusions amount in samples over time is consistent with that obtained by only SiMg. The change of inclusions amount in samples over time in case of Al/SiMg deoxidation is consistent with that obtained by only Al.
