镁质熔剂性球团矿相的多重分形谱
|
摘要
球团矿相微观结构决定其冶金物理化学性能,为透视球团矿微观结构与其宏观冶金物理化学性能之间的依赖关系,需要解决的首要关键问题是矿相微观视觉特征的提取与定量表征。以镁质熔剂性球团微观矿相为研究对象,在直观分析矿相视觉特征的基础上,采用多重分形谱分析方法,提取矿相的微观多重分形谱定量表征值f(α),并分别深度挖掘由f(α)衍生出的对称度特征值Δf、谱宽特征值Δα、容量维特征值D(0)随碱度变化的迁移规律和随矿相检测位置变化的迁移规律。研究结果表明,矿相微观视觉特征在HSV颜色空间上呈现的颜色特征未在碱度变化和位置变化上存在显著差异性;矿相微观多重分形谱分析中,Δf、Δα、D(0)3个特征值在碱度变化和位置变化上有显著的差异性,可以很好地表征碱度迁移规律和位置迁移规律。
The microstructure of the pellet phase determines the physical and chemical properties of the pellet,which depends on the relationship between the pellet microstructure and its macroscopic metallurgy physical and chemical property. The key problem needs to be solved is the extraction and quantitative characterization of the microscopic visual characteristics of the ore phase. On the basis of the visual analysis of the visual characteristics of the ore phase,the quantitative characterization value f(α)of the micro multifractal spectrum of the mineral phase is extracted by the multi fractal spectrum analysis method,and the eigenvalues,symmetry degree Δf,spectral width eigenvalue Δα,and capacity,derived from f(α)are deeply excavated. The migration rules of the D(0)with the alkalinity and the location of the ore phase are measured. The results show that the color characteristics of the mineral facies in the HSV color space are not significantly different in the change of alkalinity and the change of the position. In the analysis of the microscopic multifractal spectrum of the mineral facies,the three characteristic values of Δf,Δα and D(0)have significant differences in the alkalinity variation and the position variation,which can characterize the regularity of the alkalinity migration and the law of location migration suitably.
