Ratio of Magnesium in Prepared High Titanium Ferroalloy with Titanium Concentrate and Titanium Slag by Thermite Reduction

摘要

Titanium concentrate and titanium slag were used to prepare high titanium ferroalloy to reduce cost.In the process,the 6-9％ of aluminum consumption was replaced by magnesium.The reasonable slag system composition was used.The results indicate that the ferrotitanium of 75％ [Ti] and [Al]＜4％ was prepared.
