对攀枝花电炉钛渣氧化-还原焙烧的热力学进行了计算与分析,在此基础上,采用X-射线衍射技术测定了攀钢电炉钛渣在不同焙烧温度下氧化焙烧产物的物相组成,结果表明,钛渣氧化焙烧过程中主要发生低价钛和低价铁的氧化反应,生成金红石和M_3O_5固溶体。钛渣氧化焙烧产物还原热力学分析表明,对氧化焙烧产物进行还原可使其中的三价铁矿物还原为二价铁矿物。 The thermodynamics of oxidation-reduction roasting of Panzhihua EAF titanium slag was calculated and analyzed. Based on this, the phase composition of the oxidation roasting products of Panzhihua furnace slag was measured by X-ray diffraction. The results show that In the process of oxidation and calcination of titanium slag, the oxidation reaction of low-price titanium and low-price iron mainly occurs, resulting in rutile and M_3O_5 solid solution. The thermodynamic analysis of the reduction of the oxide calcined product of titanium slag shows that the reduction of the oxide roasted product can reduce the ferric mineral therein to ferrous iron.
