| 摘 要： | 用改进的脱氧体在20 kg密封感应炉内进行钢水脱氧实验,结果表明,脱氧效果明显,仍是一个快速有效的脱氧方法.但由于钢水中没有残存的脱氧剂,钢水的抗氧化能力较低,含氧炉气、高氧炉渣、稳定性差的耐火材料等都有可能成为钢水二次氧化的氧源,致使存在明显的回氧现象.在进行脱氧操作时,若不对钢水实现有效封闭,将难以将氧含量降至20×10-6以下.

| Abstract: | Deoxidation experiments using improved deoxidation unit are carried outin 20 kg induction furnace. Experimental results prove that deoxidizationprocess is fast and effective. But the oxygen in meltcan not be decreased below 20X10-6 because oxygen inmelt is recovered by some experimental conditions such asexisting oxidizing slag and refractory or closed experimental system wasdestroyed while measuring oxygen in melts and replacing deoxidationunit. |

| Keywords: | steel melt solid electrolyte deoxidization unpolluted |
