摘要

针对高钛低铝型R-26合金电渣重熔增铝烧钛难题，建立熔渣和渣-金间反应热力学模型分析了渣组元活度及其与铝钛成分间的关系，提出了炉渣优化方案并结合工艺试验进行验证。结果表明，模型很好地计算了渣组元活度变化。渣中不稳定氧化物0.35%

［SiO

［FeO］引起钛烧损反应；高温下Ti与Al

反应可自发进行，是导致锭上“烧钛增铝”的关键。渣中加入TiO

［Al］＜0.25%需

［TiO

Abstract

The aluminum increase and titanium loss during ESR of high Ti low Al R-26 alloy is a typical technical issue.Thermodynamic models of molten slag and slag-metal reaction were established to analyze the activities of slag components and their relationship with metal composition， and then slag optimization scheme were proposed and verified through process trial. The results indicated that， the model effectively calculated the variation of component activity in slag. The unstable oxides in slag， including 0.35%

［SiO

］ and 0.14%

［FeO］， cause the oxidation reaction of titanium. The reaction of Ti with Al

at high temperature can proceed spontaneously， as the key that caused changes in the content of Al and Ti in ingot. With TiO

added into the slag， the equilibrium Al content significantly decreased， thereby

［TiO

］ needs to be higher than 4% for

［Al］

0.25% at 1 873 K. In addition， the equilibrium Al content increased with the increase of CaO and Al

， and decreases with the addition of MgO in the slag. A recommended optimization plan "4%

［TiO

］， 2%-4%

［MgO］， 10%-15%

［CaO］ and

［Al

］ each， and CaF

balance" was proposed based on the ternary purification slag CaF

-Al

-CaO. Through the verification of process trials， the variation trend of Al content in the ingot with slag conditions and Ti content conformed to the theoretical analysis， proving that this study could effectively guide the ESR process to achieve the control of titanium loss and aluminum increase.
