高钛炉渣中Fe(Ⅱ)的测定,由于共存金属铁及低价钛化物的干扰和本身赋存状态的复杂性,至今尚难寻求准确可靠的分析方法。而高钛炉渣中Fe(Ⅲ)的测定,一般认为它在试样中不可能存在而未予研究,文献在介绍钛渣中低价钛合量测定时,也以不存在Fe(Ⅲ)为前提。在高炉冶炼的强还原气氛和1450—1500℃的高温下,可认为不存在Fe(Ⅲ)化物,加之钒钛矿高温还原性能良好,高价铁化物在软熔带已还原为FeO和部份金属铁,而且呈高
The determination of Fe (Ⅱ) in high-titanium slag is still hard to find an accurate and reliable analytical method due to the interference of co-existing metallic iron and the low-priced titanium compound and the complexity of its own state of occurrence. However, the determination of Fe (Ⅲ) in high-titanium slag is generally considered to be impossible in the sample but not studied. In the literature on the determination of low-cost titanium in titanium slag, the absence of Fe (Ⅲ) premise. In the strong reducing atmosphere of blast furnace smelting and the high temperature of 1450-1500 ℃, the absence of Fe (Ⅲ) compounds can be considered. In addition, the high-temperature reduction performance of vanadinite is good, and the high-grade ferrous compounds have been reduced to FeO and some metals Iron, but was high
