Due to the defects such as high oxygen content and more inclusions in the high Ti ferroalloy prepared by the aluminum thermal reduction

the vacuum reduction refining was used to prepare the high Ti ferroalloy with low oxygen based on the high Ti ferroalloy prepared by aluminum thermal method as raw materials.Effects of the refining temperature and refining slag on refining efficiency were investigated

and the high Ti ferroalloy with low oxygen content was characterized by XRD（X-ray diffraction）

SEM（scanning electron microscope） and chemical elemental analysis.The results show that it is necessary to ensure the refining effects with proper refining slag and the higher refining temperature.The reduction refining alloy exhibits uniform and compact structure

and oxygen content in the alloy is dramatically decreased as a result of the apparent elimination of inclusion.High Ti ferroalloy prepared with CaO-Al2O3 as refining slag at 2 000 ℃ is composed of 69.8% Ti

22.55% Fe

2.58%Al

2.02% Si and 2.60% O

meeting the technological requirements of the high quality high Ti ferroalloy.
