Sintering is a process by which a mixture of iron ores, fl uxes and coke is agglomerated in a sinter plant to manufacture a sinter product of a suitable composition, quality and granulometry to be used as burden material in the blast furnace. This process is studied and researched in the steelmaking industry in general, and in sinter plants in particular, as well as in universities and metallur...

Artificial rich ore for blast furnace use can be produced by sintering ultra-poor vanadium-titanium magnetite (PVTM) with a high-grade iron concentrate. Here, acid (R = 0.33, 0.50), self-fluxing 1.10), and high-basicity 2.60) PVTM sinters were in sinter pot. Their performances determined using the comprehensive index. The microstructures of observed metallographic microscope scanning electron m...

An optimization model for the fuel distribution of material layer with mechanism models and algorithms is presented, which can reduce ratio ore blending enhance content in upper to improve homogeneity sinter quality. The actual analyzed through granulation theoretical each unit obtained using numerical model. Then, particle size composition segregation characteristics are optimized via swarm al...

This study focused on improving recycling of carbon-bearing dusts from integrated steel plants by the composite agglomeration process (CAP), in which four types were prepared as pelletized feed, while other raw materials used matrix feed for sintering to produce product a substitute traditional iron ore sinter. It was found that carbon distribution and segregation burden layer strongly affected...

The reducibility and mechanical properties of iron ore sinter in blast furnace is critical to effective plant operation. reduction reaction sinters progresses heterogeneously owing microstructures with various mineral phases pore networks. process was investigated by semi-microbeam synchrotron X-ray multimodal analysis. Heterogeneous chemical state evolution Fe trigger sites crack formation wer...

The metallurgical property of sinter is an important factor affecting the smooth operation blast furnaces (BF), because it has a great impact on permeability BF and solid fuel rate. In order to promote combustion mineralization flux in sintering process, eventually improve strength sintered ore, series investigation segregation granulation by coating were carried out, including pot experiments,...

The adjustment of sintering raw materials has a decisive influence on the composition blast furnace slag and properties sinter. In order to smelt high-quality molten iron in furnace, sinter must be properly adjusted so that metallurgical are optimal for quality conducive smooth operation furnace. view huge difference price materials, this paper proposes an automatic ore blending model quickly c...
