The sintering basic characteristics of iron ore play a key role in the process of sintering. In this study, the effects of B 2 O 3 on the assimilation characteristics, softening temperature, fluidity of liquid phase, compressive strength of bonding phase, and microstructure of the mixed fine powder of hematite and vanadiumtitanium magnetite (HVTM) are studied.
Sintering theory was traditionally developed either as the application of complex diffusion or viscous flow mechanisms to a simple geometry or as complex evolution of microstructure with simple diffusion mechanisms. For example, the bulk modulus can be obtained from the solution of the problem of hydrostatic loading of the chosen representative ...
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 ...

Metal Ore Mining Global Market Report 2019 (1) The metal ore mining market size is expected to reach 660 billion by 2022, significantly growing at a CAGR of around 10% during the forecast period. The growth in the metal ore mining market is due to the expectation of greater stability in the commodity prices, and rising demand for iron ore products from developing countries .
Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slagforming agents and solid fuel (coke).
Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little .

With the increase of iron ore consumption in iron and steel industry all over the world, obvious degradation of high quality iron ores occurs,1,2) some low grade and high SiO2 iron ores are also newly developed, 3) which leads to increase of SiO2 content in the sinter mixture, and then increase of slag content of sinter. In order to keep the grade

Sintering is a widely used method to agglomerate ironcontaining finegrained materials. In sintering the ore fines, concentrates, fluxes, and coke breeze are thoroughly weighed, moistened, and mixed. The sinter mix is fed on the grate of the sintering machine to make a –1 m high bed. The grate is an endless strand of slowly moving pallets.
