However, one of the significant consumables in the iron ore sintering process is the coke breeze as a fuel that imparts the heat to the sinter base mix to convert into agglomerate. In most cases, coke breeze is used as fuel for the sintering process due to its low volatile content, high calorific value, and low reactivity [3].

During the sintering process, sinter fuels are commonly used to provide the required energy. The coke breeze comes from coking plant (typically less than 3 mm in size) and is widely used due to ...

54.7 Summary. In this chapter, we learned that three main ferrous burden materials are used in BF operation; lump ore, sinter, and pellets. The types of iron ores used to produce these three ferrous charge materials and the related production methods were described. The various analysis methods used to determine the quality of the BF charge ...

Section snippets Outline of sintering process. Iron ore sinter is an ordinarily utilized iron-bearing burden in BF iron-making unit. The sintering agglomeration procedure aims to form high strength sinter including granulating of the mixed materials, distributing the granulated materials and then igniting the fuels (coke or coal), sintering the iron …

Raw materials. Commercially supplied iron ore pellets and sinter of size range 10–13 mm are utilised in the present study. Comparable to the utilisation in the industrial blast furnace, two types of olivine fluxed pellets (types 1 and 2) and one type of iron ore sinter are mixed in 40:20:40 ratio to form a ferrous raw material bed.

ABSTRACT. Sintering is an agglomeration process that fuses iron ore fines, fluxes, recycled products, slag-forming elements and coke. The purpose of …

In this study, the commercial simulation software COMSOL was used to establish a model for simulating the cooling process of the iron ore sinter. Moreover, three different gas flow rate (1.5, 3 ...

The process of sintering is basically a pre-treatment process step during iron making for the production of the charge material called sinter for the blast furnace from iron ore fines and also from metallurgical wastes (collected dusts, sludge and mill scale etc.). The sintering technology was originally developed for the purpose of utilizing ...

Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is …

Based on the particle size, iron ores are classified as iron ore fines (<10 mm) or iron ore lump (6.3–31.5 mm); iron ore fines are first processed in a sinter plant, while lump ores can be charged into the blast furnace (BF) directly. Iron ore lump is the lowest cost iron bearing material for the BF burden.

Iron ore sintering is a major source of gaseous and particulate pollutants emission in iron smelt plant. The aim of present study is to characterize the volatile organic compounds (VOCs) emission profiles from iron ore sintering process. Both sinter pot test and sinter simulation experiment were con …

High grade iron ore less than 10% of the total reserves. ROM iron ore with Fe less than 58 – 60% discarded as waste. After beneficiation iron ore availability can improve by about 50%. Steel community and the country demand technological solutions for utilising low grade ores. The technology task that would be imperative: 1.
