Influence of limestone particle size on iron ore sinter

In sinter plant fluxes including limestone and dolomite are added to improve the sinter properties of iron ore and to provide an appropriate slag composition of the blast furnace. The raw material stone size affects the sinter process considerably because the sinter productivity and quality are strongly dependent on the green permeability of the bed, which is determined by the particle size

Theory and Practice of Sintering of Iron ore IspatGuru

The iron ore mean particle size affects the permeability of the sinter bed, which in turn, influences sinter microstructure and productivity. The larger particles favour diffusion bonding, and smaller articles favour slag bonding in the sintering process. A high fraction of small particles forms excessive amounts of melt, resulting in a deterioration of the sinter quality, while the sinter

The main purpose of this study was therefore to examine the effect of particle size distribution control of the raw material mixture on the quality of the produced sinter. Background Only a limited amount of fine iron ore particles can be directly charged to the blast furnace, as they are

Influence of Iron Ore Fines Feed Size on Microstructure

Sinter with iron ore mean particle size of 2.59 mm (Classifier fines) yielded better sinter strength with lower fines (–5 mm) and lower RDI. Higher sinter strength is due to effective distribution of acicular silico ferrites of calcium and alumina (SFCA) phases. The improvement in sinter RDI is due to the change in proportion of magnetite and hematite phase with flame front speed.

Simulation and optimization of waste heat recovery in

The waste heat utilization decreases when the sinter particle size increasing, as given in Table 5. This is because the area of heat exchange between gas and solid and the heat which is taken away from the sintered bed by the gas in the same periods reduce when the sinter particle size increases. That is, the cooling rate, the processing

Inter−particle water infiltration dynamics of iron ore

Six different types of iron ore fines were studied, including two porous Australian sinter fines (Ores A and B), two micro-porous to dense Brazilian sinter fines (Ores C and D), a Canadian magnetite concentrate (Ore E) and a Brazilian pellet feed (Ore F). The size fraction under 1 mm was typically selected in the present stone to study the inter-particle water infiltration of iron ore fines.

Influence of nut coke on iron ore sinter reducibility

AbstractOne of the most important factors to increase the economic efficiency of the blast furnace process is to reduced coke losses (undersieve product known as nut coke). In recent years there has been increased interest in mixing nut coke in the sinter layers. In order to clarify the influence of nut coke on sinter reducibility, sinter and sinter–nut coke mixtures were isothermally

A study on the effect of coke particle size on the therm

particle size (Loo and Wong, 2005). Coke is the major source of energy in the iron ore sintering process, and hence its particle size distribution has a crucial influence on the sintering productivity. The coarse coke particles in the sintering mixture result in a heterogeneous thermal profile along the charge bed. Furthermore, the higher temperatures near the coarse particles might produce an
