冶炼钒钛磁铁矿新流程中的熔分渣和深还原渣的熔化性温度与(TiO_2+Ti低+Al_2O_3)/(CaO+MSO+FeO)比值呈对数正相关关系。在其它条件近似不变时,随Al_2O_3增加和TiO_2减少,渣熔化性温度由高向低变化;但当Al_2O_3含量较高时,熔化性温度会再升高。随MgO含量的增加,渣熔化性温度降低幅度较大,但当MgO含量大于20％后,渣熔化性温度会急剧升高。 析出相中以黑钛石为主,黑钛石矿物化学式中Al/Mg(原子数比)值高时,熔渣的熔化性温度高。还原渣析出相中∑TiO_2比原渣中含量富集约10个百分点。
The melting temperature of slag and deep reduction slag in the new process of smelting vanadium titanomagnetite has a logarithmic positive correlation with the ratio of (TiO 2 + Ti low + Al_2O_3) / (CaO + MSO + FeO). When other conditions are not changed, the melting temperature of slag changes from high to low with the increase of Al 2 O 3 and the decrease of TiO 2. However, when the content of Al 2 O 3 is higher, the melting temperature will increase again. With the increase of MgO content, the melting temperature of slag decreased greatly, but when the content of MgO was more than 20%, the melting temperature of slag increased sharply. In the precipitated phase, black titanium is the main component, and when the Al / Mg (atomic ratio) value in the black-titanium mineral chemical formula is high, the melting temperature of the molten slag is high. Reducing slag precipitation phase ΣTiO_2 content than the original slag content of about 10 percentage points.
