| 摘 要： | 在高温钼丝炉内向铁液中加入SiMg合金、Al及复合添加这两种脱氧剂进行脱氧,并改变其添加顺序,分析过程样中溶解氧、全氧、残镁量及夹杂物随时间的变化.结果表明:1873K时,铁液中复合添加0.02%(质量分数)的SiMg和0.03%(质量分数)的Al脱氧,其脱氧程度与只用0.05%的SiMg脱氧相当,而镁的收得率得到提高.SiMg/Al处理的试样中夹杂物数量随时间的变化与只用SiMg处理时一致,而Al/SiMg处理的试样中夹杂物数量随时间的变化与只用Al处理时一致.

| 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 f... |
