摘要: 以酸溶性钛渣为原料,对其进行传统加热氧化焙烧实验研究。考察了焙烧温度及保温时间对样品中二氧化钛、硫、碳含量的影响。结果表明:随着焙烧温度升高,氧化焙烧过程中低价钛、铁以及氧化亚铁的氧化使物料总量增加,而钛总量不变,导致焙烧后物料中二氧化钛含量随着焙烧温度的升高而降低;随着保温时间增加,各成分的氧化反应进行得更彻底,物料中二氧化钛的含量不断降低;随着焙烧温度的升高及保温时间的增加,碳与硫的脱除效果明显,其含量不断降低。

关键词: 酸溶性钛渣, 传统加热, 氧化焙烧, 二氧化钛

Abstract: The traditional heating oxidation roasting experiment research with acid soluble titanium slag as the raw material was carried out.The influences of different roasting temperature and holding time on the contents of titanium dioxide,carbon, and sulfur in the samples were investigated.The results indicated that: with the increase of roasting temperature,because the low valence titanium,Fe,and FeO took place oxidation reactions,and made the total amount of sample increase but the over- all titanium content did not change,so the content of TiO2 decreased;with the increase of holding time,the content of TiO2 decreased continuously because the reactions of each component became more thoroughly;investigated the influences of different roasting temperatures and holding times on carbon and sulfur contents in the samples,the results showed that with the increase of temperature and holding time,carbon and sulfur removal effect was obvious,and the contents decreased with temperature and time increase.

Key words: acid soluble titanium slag, traditional heating, oxidation roasting, titanium oxide
