Influence of SiO₂ Content on Fractal of Grain Distribution in Low Silicon Sinter

Abstract:

Grain size distribution in the sinter is an important index sign to measure the quality of sinter. In this paper, according to the fractal theory and the contrast experiment of sinter, the fractal characteristic of grain size distribution of sinter with low SiO₂ is discussed. The relation between the fractal dimension and content of SiO₂ is proposed. Combine with the SEM graphs of the sinter with low SiO₂, the relation between the fractal dimension and microstructure of sinter with low SiO₂ is also analyzed. Pass to the quantificational description of the grain size distribution of sinter with low SiO₂, to predict and optimize the grain size constitution of sinter, and offer a new idea, a new way for the further thorough research of sinter ore.
