Influencing Factors and Effects of Assimilation Characteristic of Iron
Assimilation of iron ores influenced the fluidity of liquid phase, which could also influence the bonding strength of sinter body further, and the results of bonding strength tests were shown as Figs. 8 and 9. Each sinter body was composed of a lot of sinter body units which was quasi-particles before sinter.

Iron Ore Sintering With Charcoal
The iron blast furnace is the most widely used and efficient producer of liquid iron; however, emissions from sintering and coking cause environmental pressure for the integrated steel works. The combustion of coke fines (breeze) during sintering contributes to greenhouse gases (GHG) (eg carbon dioxide) and is a source of SOx and NOx emissions.
