摘要
研究了钒钛磁铁矿熔态还原速度与渣相结构的关系,分析了钒钛磁铁矿熔态还原渣相结构的变化特征,讨论了钒钛磁铁矿熔态还原速度产生多峰特性的机制.结果表明,无铁浴时,钒钛磁铁矿熔态还原速度呈三峰特性,有铁浴时呈双峰特性,第一峰是磁铁矿还原产生的,第二峰主要是铁氧化物还原为金属Fe的结果,第三峰主要由钛氧化物还原为低价Ti和金属Ti及形成TiN,TiC所产生.
The slag structure and mechanism of multipeaks in reduction rate during smelting reduction of V-Ti containing magnetite were systematically analysed.There are three peaks of reduction rate without iron bath and two peaks with iron bath.The first peak is formed by reduction of magnetite,the second peak by reduction of ferric oxides to iron and the third mainly by reduction of titanium oxide to metallic titanium or TiC and TiN.
