| 摘 要： | 研究了LD-LF-CC和LD-ANS-OB-CC两条工艺路线对管线钢洁净度的影响.通过合理的工业试验和金相、化学等分析手段,对冶炼过程钢水中氧、氮含量和夹杂物进行了定量分析.结果表明:钢水经过LF炉和ANS-OB两种精炼工艺处理后钢水洁净度是一致的,采用LD-AND-OB-CC工艺生产某些钢种可降低成本.提出了精炼过程中吹氩工艺是去除夹杂物的主要因素.精炼处理时间40 min,钢中氧、氮和夹杂物基本达到最好水平,继续延长精炼时间钢水中夹杂物没有变化.

| Abstract: | The effects of LD-LF-CC and LD-ANS-OB-CC refining processes on the purity of pipe-line steel were investigated. The contents of oxygen, nitrogen and inclusions during refining were studied quantitatively by metallographic and chemical analysis. The results indicate that the molten steels refined by LF and ANS-OB are of same cleanness, but the product cost can be reduced by use of LD-ANS-OB-CC. Blowing argon is a main factor for removing inclusions in refining process. The contents of oxygen, nitrogen and inclusions can be reduced to a minimum, when the refining time reaches 40 minutes. |
