The inhibition effect of calcined lime (CaO) and limestone (CaCO3) on the formation dioxins during iron ore co-sintering with fly ash was investigated in a sinter pot present work. Experimental results indicated that international total toxicity equivalent concentration decreased from 1.4335 to 0.2922, 0.1048, 0.4562, 0.3098 ng I-TEQ Nm−3 under four different experimental conditions. It can be ...

This investigation aims to identify the reasons for plumes' visibility, compare stacks with other sinter plant worldwide, and suggest countermeasures completely stop visibility of emissions. The appearance stack emission changes time background color sky due scattering effect sunlight incidence angle. flue gas samples were collected at outlet control equipment observed under optical scanning el...

The phase evolution during heating of two Al2O3-free mixtures designed to form the SFC iron ore sinter bonding was investigated using in-situ X-ray diffraction over temperature range 293–1623 K. Results showed that at an oxygen partial pressure 5 × 10?3 atm, formation preceded by ?-Ca4Fe14O25 and ?-CFF (nominal composition Ca3.0Fe14.82O25) intermediate phases. On further melted Fe3O4 in a Fe2O3...

The use of biomass as fuel might solve several technological and environmental issues overcome certain challenges sinter production. In particular, revealed by comprehensive analyses, can be used for iron ore sintering. this study, we investigate the some raw pyrolysis-processed pellet types, namely wood, sunflower husks (SFH), straw, experiments, pyrolysis temperature was set to 673, 873, 1073...

Sinter hardening enables the production of P/M parts with high strength and apparent hardness after sintering, eliminating the need for a post sintering heat treatment. The availability of sintering furnaces with improved cooling capacity combined with the development of low alloy steel powders specifically designed for sinter hardening make this process particularly attractive for parts that a...
