中文摘要: 在CaCl2熔盐中,采用熔盐电解法还原钛铁矿。在槽电压分别为3.0 V和3.1 V、温度825~900 ℃时,研究了不同槽电压及电解温度对钛铁矿电解还原的影响,并对钛铁矿电解脱氧过程进行了讨论。结果表明,在电解过程中铁优先还原,反应区中铁含量高时易形成TiFe2合金;槽电压对钛铁矿电解产物有重要影响;提高反应温度有利于促进铁钛的互扩散合金化过程。
Abstract:Ilmenite was reduced by molten salt electrolysis in CaCl2 melts. Effects of cell voltage and temperature on electrolysis process were investigated under the conditions of cell voltage of 3.0 V or 3.1 V and temperature of 825~900 ℃. Process to remove oxygen from ilmenite was discussed. The results show that iron in ilmenite is reduced firstly. TiFe2 alloy is easy to form in reaction area where iron content is high. Cell voltage has a big influence on electrolysis product. Raising reaction temperature is beneficial for diffusion-alloying process of titanium and iron.
