Converter dust is a by-product produced in the process of converter steelmaking. Due to the addition of zinc-containing raw materials during steelmaking, the zinc content in the converter dust continues to increase and cannot be used directly. In this article, ICP, laser particle size analysis, XRD, and SEM-EDS and other analytical means are adopted to analyze the converter dust produced by wet dust collecting in converter steelmaking. The results show that, zinc-containing converter dust mainly contains such elements as Fe, Ca, Zn, etc. Among them, w(Fe) is 48%～50%, and the phases are Fe₃O₄, Fe₂O₃ and FeO; w(Zn) is 3.5%～3.7%, the phases are ZnO and ZnFe₂O₄, and mainly exist in the form of ZnFe₂O₄; the particle size distribution of zinc-containing converter dust is narrow, mainly between 0.1 and 1 μm, and 90% of the particles has a particle size of less than 1 μm. Besides, based on the analysis of its characteristics, it is found that the currently commonly used zinc-containing dust disposal methods exist a certain inapplicability. It is necessary to seek more effective and economical technical methods to solve the problem of the reuse of zinc-containing converter dust.
