利用电炉炼钢烟尘生产氧化铁红

以钢厂电炉烟尘为原料 ,通过宏观和微观分析 ,研究了烟尘的结构和物化性质。采用物理和化学联合筛选的方法 ,有效地清除了杂质 ,通过高温煅烧变相 ,获得了纯度达 99.5 % ,Si O2 质量分数为 0 .1%的氧化铁红 ,并对实验过程、酸浓度以及滴定速度和 p H值等对实验的影响进行了考察 ,得出了较理想的实验数据。

Production of Iron Oxide Red from EAF Dust

Thestructure and physico-chemical prop erties of EAF dust were studied by macroscopic and microscopic analysis.The impu rities were removed by combined physical and chemical method and the iron oxide red of 99.5% purity and 0.1% SiO 2 was obtained by high temperature calcinati o ns.The influence of acid concentration,titration process and pH value was invest igated.
