3.1 Impact of Biopellet on Sintering Temperature Profiles. Figure 3 shows the temperature profile observed during iron ore sintering process at different proportions of biopellet. With an increase in biopellet the maximum temperature within the sinter bed reduces. In the presence of biomass, the water content required to granulate the sinter …
Sintering is an agglomeration process that fuses iron ore fines, fluxes, recycled products, slag-forming elements and coke. The purpose of sintering is to obtain a product with suitable ...
1. Introduction. In the metallurgical ironmaking process, sinter is the main raw materials fed into the blast furnace to produce molten iron. To produce sinter, iron ore fines are mixed with coke and fluxes, and granulated in a granulator with the addition of water; the granules are then distributed to the sintering machine for ignition, exhaust, sintering …
machine, and sintered ore is produced by calcinating at approximately 1 300°C. As a pretreatment, the powder ore ... The gangue content increased as the grade of the iron ore decreased. In granules composed of intermediate and fine ores, the influence of the gangue component on the com-pressive strength is expected to be large. Therefore, in this
In iron ore sintering, the granulation process is the first and an important step. As the fine particles adhere to the coarse coke particles, the NO x emission generated from coke combustion may be expected to be influenced by that adhering layer. In this study, the granule size distributions and adhering ratios were evaluated by a granulation model. …
