摘要
在CaCl_2熔盐中,采用熔盐电解法还原钛铁矿。在槽电压分别为3.0V和3.1V、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TiFe_2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。
Ilmenite was reduced by molten salt electrolysis in CaCl_2 melts.Effects of cell voltage and temperature on electrolysis process were investigated under the conditions of cell voltage of 3.0 Vor 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.TiFe_2 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.
