Utilization of charcoal in the iron-ore sintering process

2021-5-15  Sintering is an agglomeration process that is used in the iron industry to prepare ne grained iron bearing materials for use in the blast furnace. Sinter com-position usually depends on chemical composition of input materials, carbon content, oxidation potential of the gaseous phase, and temperatures in the sintering bed [1].

Mechanism and Prevention of

2017-12-20  The mechanisms of agglomeration and defluidization and fluidization characteristic of iron oxide particles were investigated based on the theory of surface diffusion, interface reaction, surface nano/microeffect, and phase transformation. Moreover, a mathematical model was developed to predict the high-temperature defluidization behavior by the force-balance and plastic-viscous flow mechanism ...

2020-11-1  1. Introduction. Iron ore sintering is an important hot agglomeration pre-process for ironmaking in most integrated steel mills. This process converts a mixture of ore fines, fluxes, return fines and plant dust to sinter by partial melting and re-solidification of the granulated particles in a moving grate, in which the coke breeze is typically used as solid fuel with mixing ratios of 3–5 wt ...

Metals Special Issue : Ironmaking and Steelmaking

The increased iron content in the agglomerate can be achieved by adjusting the raw material ratio in which iron ore materials are added to the agglomeration mixture. If the ratio is in favor of iron ore this reflects in lower iron content in the resulting agglomeration mixture.

2011-10-1  Owing to the depletion of world lump iron ore stocks, pre-treated agglomerates of fine ore (sinters) are making up a growing proportion of blast-furnace feedstock (currently ∼80%). SFCA is the most important bonding phase in iron ore sinter, and its composition, structural type and texture greatly affect the physical properties of the product.

Bulk materials such as iron ore, coal, pellets and sinter are at the core of the steelmaking process. From transporting raw materials from the mines to the plant by wagons, moving materials on conveyor belts to the blast furnace and the actual charging of the furnace, efficient handling and processing of those materials is critical to achieve ...

Chemical looping hydrogen production with modified

The CuO–iron ore exhibited the highest carbon capture efficiency until a reduction time around at 50 min. Compared with the NiO–iron ore and CeO 2 –iron ore, the CuO–iron ore was more suitable for the application of the chemical looping combustion process for carbon capture. It was noted that there was a slight decrease in the carbon ...
