| 摘 要： | 以金属热还原法制备的V-Ti-Fe中间合金为原料,采用喷吹造渣的方式对其进行精炼研究,实验考察了渣系组成和精炼温度对精炼效果的影响.结果表明:渣体中m(CaF2)/m(CaO)值为3.0,TiO2用量为总渣量的10%,用渣量为合金用量的35%,精炼温度为1 600℃时,精炼效果较好;精炼后合金中的Al质量分数由7.11%降到了2.61%,合金中的Si质量分数变化较小,仅由1.25%降到了0.97%.XRD和SEM分析表明,精炼后合金中没有出现氧化物相,精炼有效地去除了合金中的氧化物夹杂,降低了合金的成分偏析.

| Abstract: | The spray refining process was carried out to reduce the impurities of V-Ti-Fe master alloy.The influences of slag compositions and temperature on refining effect were investigated.The results showed that when the ratio of m(CaF2)/m(CaO) is 3.0,the slag amount is 35% of the alloy amount,the TiO2 amount is 10% of the slag amount and the refining temperature is 1 600 ℃,a good refining effect is obtained.The content of Al decreases to 2.61% from 7.11% after the refining process.However the content of Si just decreases to 0.97% from 1.25%,the change range is smaller.XRD and SEM results showed that the refining process can remove oxide inclusions effectively.In addition,the componential segregation of the alloy is reduced after the refining process. |
