| 摘 要： | 在实验室中使用高温管式炉对以工业纯铁为原料配制的帘线钢进行脱氧和顶渣熔炼，研究了顶渣成分对MnO-Al2O3-SiO2类夹杂物的成分的影响。结果表明，在顶渣碱度为0．7～1．36时，随着顶渣中Al2O3含量的增加，夹杂物中的Al2O3含量也随之增加，当顶渣中Al2O3含量低于8％时，MnO—Al2O3—SiO2类夹杂物的成分在塑性区范围，通过控制脱氧条件和项渣的成分可以把MnO-Al2O3—SiO2类夹杂物的成分控制在塑性区内的。

| Abstract: | The effect of top slag composition on MnO-Al2O3-SiO2 inclusion composition was studied by controlling the condition of deoxidization and the composition of top slag in an experimental furnace in which the tire cord steel were melt. The Al2O3 content in the inclusion increased with the Al2O3 content of top slag increasing while the basicity of top slag was within 0.7-1.36. Plastic MnO-Al2O3-SiO2 inclusion existed while the Al2O3 content of top slag was below 8%. The composition of MnO-Al2O3-SiO2 inclusion can be controlled within the plastic area by controlling the condition of deoxidization and the composition of top slag. |
