Therefore, the carbon and Cl content of the raw materials used for iron ore sintering are important to the formation of dioxins. This is supported by Kawaguchi et al. (2002c), who reported that the properties and contents of the solid fuels and chlorides in the raw mixture significantly affect dioxin emissions during the iron ore sintering process.

The iron ore in the sintering dust was mainly magnetite, a small amount of hematite and gangue. Moreover, a small amount of quicklime also existed in the sintering dust due to using it as a solvent for the sintering process (Wu et al., 2022b). The peak intensity of metallic iron rose with the temperature, while peaks of magnetite and hematite ...

The basic hightemperature properties of iron ore play a crucial role in optimizing sintering and ore blending, but the testing process for these properties is complex and has significant lag time, which cannot meet the actual needs of ore blending. A prediction model for the basic hightemperature properties of iron ore fines was thus proposed based on a combination of machine learning ...

The sinter plant that converts the iron ore fines into a desirable blast furnace feed, offers an avenue for recycling wastes. One of the several wastes that are produced at an iron and steel plant is the undersized pellet fines, which cannot be directly used in iron making. The present study evaluated the influence of these pellet fines on the sintering process. 5 experiments were conducted ...

2. 2 Sintering is one of the most important steps and a unique process in manufacturing of ceramic products. Ceramic materials have high melting point and brittle so that sintering can be employed for their preparation rather than applying high pressure or other techniques. Fortunately, for the ceramic community, sintering provides an alternative and useful process for the shaping and ...

FIXING OF FEED RATE : For sending raw mix to sinter machine for sintering, fixation of feed rate of materials is done considering capacity of the sinter machine and quality requirement of blast furnace. Feed rate fixed is : Iron ore fines 250 T/hr. Flux 75 T/hr. ( Feeding of Flux depends on available lime in sinter required in blast lime means CaO SiO2 in sinter.)
