摘要
在实验室中用高温管式炉对用工业纯铁配制的帘线钢进行脱氧和顶渣熔炼,研究了炉渣成分对夹杂物成分的影响.在炉渣碱度一定的情况下,随着炉渣中Al2O3含量的增加,夹杂物中的Al2O3含量也随之增加.当炉渣中的Al2O3含量低于8％时,夹杂物中的成分在塑性区.通过控制脱氧条件和项渣成分可以把夹杂物的成分控制在塑性区内.
The effect of top slag composition on CaO-Al2O3-SiO2 inclusion composition was studied by controlling the condition of deoxidization and composition of top slag in experimental furnace in which the tire cord steel was melt. The content of A12O3 in inclusion increased with that in top slag increasing while the basicity of top slag was fixed. Plastic inclusion presented while the content of A12O3 in top slag was below 8%. It is concluded that the composition of the inclusion can be controlled within the plastic area by controlling the condition of deoxidization and the composition of top slag.
