中文摘要: 利用攀枝花产的电炉钛渣铝热还原一步合成Ti-Al-xFe-ySi多元合金，探索CaO对渣金分离、合金收率及钛收率的影响。当CaO/Al=1.1时，制备的熔渣主要生成了低熔点Al2O3?CaO和7Al2O3?12CaO相，渣金分离效果最好。合金收率达到62%，Ti收率达到92%，合金中氧含量仅为1.32%。制备的合金主要物相为TiAl3、TiAl相，而渣中还原出来的Fe替代了TiAl3中的部分Ti形成了Al3Ti0.75Fe0.25物相，而Si主要与合金中的Ti结合生成了Ti5Si3相，合金中还含有少量的C与TiAl和TiSi相形成了Ti3SiC2和Ti2AlC新相。

Abstract:Ti-Al-xFe-ySi alloy was synthesized from electro-titanium slag in Panzhihua by electro-aluminothermic reduction. Effect of CaO addition on slag-gold separation, alloy yield, and titanium yield was investigated. With CaO/Al of 1.1, low melting point phases such as Al2O3?CaO and 7Al2O3?12CaO are mainly produced from reduction slag, and yield of alloy and Ti is 62% and 92% respectively with oxygen content in alloy of 1.32%. Main phase of alloy is composed of TiAl3 and TiAl, Fe in slag replaces Ti in TiAl3 to form Al3Ti0.75Fe0.25, and Si is mainly combined with Ti in alloy to form Ti5Si3. Small amount of C in alloy combines with TiAl and TiSi to form new phase of Ti3SiC2 and Ti2AlC.
