Sintering ofiron Ore Fines, and Raw Materials for Bhilai ...

2012-7-20  the primary object of sintering in most cases is the utilisation of blast-furnace flue dust and ore fines in such a way as to improve the characteristics of the blast furnace burden. When agglomeration of finely divided ore into lumps or caked material is accompanied by heating, it is due to a softening—an incipient fusion without

Theory and Practice of Sintering of Iron ore – IspatGuru

Sintering of iron ore is a generic term which is used to describe the process whereby a sinter mix (raw mix or green mix) of iron ore fines, fluxes, fuel (coke breeze) and plant return fines (e.g. mill scale, blast furnace dust, and returned sinter fines etc.) are converted into a particular form of agglomerate.

Advances in Mathematical Modelling of Sintering ...

The prediction of sintering performance of iron ore fines and the possibility of targeted optimisation of specific sinter properties are very important for both the iron ore industry and related research organisations. Physical pilot-scale sinter runs require large amounts of raw materials and are expensive, so it is critical to target large test work programs with many different sintering ...

High-temperature performance prediction of iron ore

2017-8-23  various iron ore fines provide the possibility for perform-ance complementation to improve sinter quality [7–15]. A typical method used to determine the high-temperature performance of mixed ore fines is by mini-sintering test, which is accurate if it is performed repeatedly [16–18]. The other less laborious method is to perform calculations by

A Novel Approach for Utilization of Ultra‐Fines Iron

The current study presents a novel approach for the utilization of ultra‐fines iron ore (−0.2 mm) in sintering process through its conversion into mini‐pellets (4–9 mm). The mini‐pellets were composed of ultra‐fine iron ore and calcium hydrate while coke fines were used as a coating layer. One part of mini‐pellets was cured with CO 2 to improve the ...
