用电炉还原熔炼含钒金属化原料是处理乌拉尔钛磁铁矿有前途的方案之一。因此,研究含钒电炉渣的性能,特别是研究从渣中化学提取V~2O~5的可能性,具有重大的意义。 在半工业性电弧炉(ДСП—0.5)中,对具有不同氧化钙和二氧化钛含量的卡奇卡纳尔金属化球团曾进行了一系列还原熔炼试验。表1列举了А、Б、В三炉最有代表性的电炉熔炼过程渣的化学成分的变化。在А炉中使用了含CaO5.0％和SiO~24.6％的自熔性球团矿,而在Б和В炉试验中则使用了含CaO2.6％和SiO~25.2％的低碱度球团矿。此外,在В炉中,
Smelting of vanadium-containing metallurgical raw materials by electric furnace reduction is one of the promising solutions for the treatment of Ural titanium magnetite. Therefore, it is of great significance to study the properties of vanadium-containing electric furnace slag, especially the possibility of chemical extraction of V ~ 2O ~ 5 from slag. In a semi-industrial electric arc furnace (ДСП-0.5), a series of reductive smelting tests have been performed on Kacaccana metalized pellets with different calcium oxide and titanium dioxide contents. Table 1 lists the most representative of the three furnace А, Б, В melting furnace slag chemical composition changes. Self-fluxing pellets containing CaO 5.0% and SiO ~ 24.6% were used in the А furnace while low-alkalinity balls containing CaO 6% and SiO-25.2% were used in the Б and В furnace tests Mission. In addition, in the В furnace,
