摘要 为研究顶渣改质工艺对无间隙原子钢(IF钢)顶渣氧化性与钢中夹杂物的影响,在不同改质工艺中的多个位置取渣样和钢样进行分析.结果表明:在氩站加入改质剂的改质效果最好.以渣中全铁和氧化锰质量分数w(T. Fe+MnO)表示炉渣的氧化性,改质前后炉渣氧化性下降了8. 73%.与真空循环脱气(RH)脱氧合金化后和RH精炼结束后加入改质剂改质工艺相比,氩站改质工艺条件下的中包夹杂物数量密度分别下降了38. 5%和36. 0%. RH精炼结束后,钢中夹杂物数量较少,但在炉渣氧化性高时,炉渣向钢中传氧,使中包钢中夹杂物上升. To study the influence of slag denaturalization process on the top slag oxidation and inclusions in interstitial free ( IF) steel,the slag and steel samples were analyzed and taken from different positions in different slag denaturalization experiments. In the results,the best denaturalization effect is obtained by added the denaturalization agent in argon station,the slag oxidizability,indicated as the content of total Fe and MnO by mass in slag,w( T.Fe + MnO) ,decreases by 8. 73%. Compared with the slag denaturalization process added the denaturalization agent after RH deoxygenation-alloying and RH refining,the number density of inclusions in slag denaturalization process added the denaturalization agent in argon station is decreased by 38. 5% and 36. 0%,respectively. After RH refining, the number of inclusions in steel is less,but when the slag is in high oxidizability,the oxygen is transferred from slag to steel, which makes the number of inclusions in steel rise.
