| 摘 要： | 在实验室条件下,采用高温钼丝炉对用45钢和重轨钢熔炼成的帘线钢进行脱氧和渣钢平衡试验,研究了精炼渣组分对夹杂物形态的影响。结果表明:在精炼渣碱度为0.8～1.2时,夹杂物中Al2O3含量和钢中Als随精炼渣中Al2O3含量的增加而增加。把精炼渣Al2O3质量分数控制在10%以下时,能够使CaO-SiO2-Al2O3夹杂物处于塑性范围内。因此,在低碱度条件下,通过Si、Mn脱氧和调整精炼渣中Al2O3含量来控制夹杂物的形态是可行的。

| Abstract: | The effect of top slag composition on CaO-SiO2-Al2O3 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 by 45 steel and heavy rail steel. As a result, the Al2O3 content in the inclusion and Als in steel increased with the Al2O3 content of top slag increasing while the basicity of top slag was within 0.8-1.2. Plastic CaO-SiO2-Al2O3 inclusion existed while the Al2O3 content of top slag was below 10%. The composition of CaO-SiO2-Al2O3 inclusion can be controlled within the plastic area by controlling the condition of Si. Mn deoxidization and the composition of top slag. |
