摘要
本文的主要目的是探索一种可持续的方法,回收钢渣中有价值的成分再利用。根据对钢渣回收利用的创新原理,使用热解重量分析法在1623~1823 K的温度范围内,在不同的气氛中对液态渣中的氧化亚铁氧化进行了实验研究。本实验中采用合成剂(二元和三元渣系)和工业炼钢渣,使用X射线衍射法进行反应产物的分析,并确认了通过氧化可将炼钢渣中的无磁性含铁化合物转变为磁性的Fe3O4。
The present work is aimed at the development of a new sustainable method for the utilisatioin of valuable elements from the steelmaking slag.In the framework o fthe innovative concept earlier proposed by the authors for utilisation of steelmaking slags,oxidation of iron mono-oxide in the temperature range 1623~1823K using thermogravimetry technique.Synthetic(binary and ternary slag system) as well as industrial steelmaking slags were used in the experiments.Analysis of the reaction products was carried out using X-y diffraction method.A possibility to transform the non-magnetic iron bearing compounds to magetite in the steelmaking slag by oxidation has been confirmed.
