氟石的铁上的合成凝块过程(帽子) 的效果集中 sintering 被调查。当使用帮助热气流和提高的镁氧化物(MgO ) 内容的帽子时,泉华的收益和质量极大地被改进。为氟石的铁的常规 sintering 专注,由于有约束力的阶段的更低的粘性和液体阶段的更高的流动性,泉华与大薄墙的洞被形成,泉华的力量因而被败坏。新奇过程表格合成在在哪个酸,小团在基本泉华被嵌入聚结成块的。小团与互连赤铁矿(Fe2O3 ) 的晶体是稳固的并且磁性(Fe3O4 ) 。为基本 sintering,在增加 MgO 以后,融化的阶段的粘性增加,流动性减少;并且钙和铝 silico 铁酸盐和镁铁酸盐与完美的晶体和好 sintering 微观结构被形成。
The effect of composite agglomeration process (CAP) on fluoric iron concentrates sintering was investigated. The yield and quality of the sinter are greatly improved when using CAP assisted with heat airflow and enhancing magnesium oxide (MgO) contents. For conventional sintering of fluoric iron concentrate, due to lower viscosity of binding phase and higher fluidity of liquid phase, the sinter is formed with large thin-walled holes and the strength of the sinter is deteriorated consequently. The novel process forms composite agglomerate in which acid pellets are embedded in basic sinter. The pellets are solid with interconnecting crystals of hematite (Fe2O3) and magnetic (Fe3O4). For basic sintering, after adding MgO, the viscosity of the melting phase increases and the fluidity decreases; and calcium and aluminum silico-ferrites and magnesium ferrite are formed with perfect crystals and good sintering microstructure.
