Increase in productivity of sintering machine and sinter quality by improvement of ore preparation for sintering
Journal Title: Metallurgical and Mining Industry - Year 2017, Vol 9, Issue 1
Abstract
In the paper, economic and technology factors proving need of use of sintering ore as a ferriferous component of sintering furnace charge are considered. On the basis of analysis of material structure of ferriferous, fuel and flux components of sintering furnace charge, it is shown that the easiest way of improvement of composition of furnace charge is improvement of particle size distribution of sintering ore, which content in furnace charge reaches 20%. On the basis of influence of the analysis of granulometric characteristic of sintering ore fed to furnace charge composition for sinter production on sintering machine operation and indicators of sinter use, the technology of sintering ore preparation is suggested. This technology is based on truncation of the initial granulometric characteristic of sintering ore "from below" (i.e. removal of a part of fine fractions from initial composition) and "from above" (i.e. removal of "coarse" part from initial composition with subsequent recrushing and return of crushed product to furnace charge).
