The shaft furnace is where iron ore is converted to metallic. Iron oxide, in pellet or lump form, is introduced through a proportioning hopper at the top of the shaft furnace. As the iron ore descends through the furnace by gravity flow, it is heated, and the oxygen is removed from the iron ore (reduction) by counterflowing gases that have a high H and CO content.

Optimization of iron ore blending in the COREX shaft furnace X. Liu1, C. Liu2, B. Wang2, and F. Ye2 Synopsis To extend the variety of lump ores that are used in the COREX shaft furnace and to optimize iron ore blending, the original evaluation method for iron
Shaft Furnace Technology From China For Iron Ore Pellet We are a largescale manufacturer specializing in producing various mining machines including different types of sand and gravel equipment milling equipment mineral processing equipment and building materials equipment.
Oct 10, 2016· MBF is a vertical shaft furnace with a crucible like hearth. Burden materials consisting of iron ore, coke or charcoal used as a reducing agent as well as fuel, and fluxes, usually limestone or dolomite, are charged into the top of the furnace. The furnace works on
In iron processing: History. Stone-built shaft furnaces, on the other hand, relied on natural draft, although they too sometimes used tuyeres. In both cases, smelting involved creating a bed of red-hot charcoal to which iron ore mixed with more charcoal was added. Chemical reduction of the ore then occurred, but, Read More
In ancient times, smelting involved creating a bed of red-hot charcoal in a furnace to which iron ore mixed with more charcoal was added. The ore was chemically reduced ( see oxidation-reduction ), but, because primitive furnaces could not reach the melting temperature of iron, the product was a spongy mass of pasty globules of metal intermingled with a semiliquid slag .

b National -local Joint Engineering Research Center of High efficient exploitation technology for Refractory Iron Ore Resources, Shenyang 110819, P.R. China rather than shaft furnace and
The present invention provides a roasting technology of a vanadium titano-magnetite oxidized pellet for a shaft furnace, and the roasting technology is as follows: fine grinding vanadium titano-magnetite into ore grains with the granularity of smaller than 200 meshes being more than 70%, and then drying; adding a 10 to 15 wt % organic binder for even mixing to pelletize; performing oxidizing
He has also spent several years working on Midrexs technology for using pure hydrogen, MIDREX H2. Building on experience In a conventional MIDREX Plant, the reducing gas needed to feed the shaft furnace in which iron ore is converted to DRI is generated in a reformer. The reformer itself is
The iron and steel sector is the second-largest industrial user of energy, consuming 616 Mtoe in 2007 and is also the largest industrial source of CO2 emissions. The five most important producers China, Japan, the United States, the European Union and Russia account for over 70% of total world steel production. Smelting reduction is a term assigned to a group of upcoming ironmaking
In the first step, iron ore is reduced to sponge iron in a shaft furnace by means of reducing gas. In the second step, the reduced iron is melted in the meltergasifier vessel. Reducing gas (CO and H 2) used in the reduction shaft is supplied by gasification of coal by means of oxygen, forming a fixed or fluidized bed in the meltergasifier. The partial combustion of the coal in the meltergasifier generates the heat to
May 12, 2015· Reduction shaft (RS) for the direct reduction of iron ore is one of the two major reactors in Corex. This work uses a twodimensional slot model to investigate the thermal behavior of the gassolid flow in the RS by a combined computational fluid dynamics and discrete element method approach.The general heat transfer characteristics are
With the iron-ore based route, hot metal is mostly produced from iron oxide ores in blast A blast furnace is a shaft-shaped aggregate that operates according to the counter-current streams principle. In the case of pelletising, the finest of ores (the pellet feed) and concentrate with grain sizes of well. YouTube Channel. Read more
Apr 27, 2016· HYL, also known as Energiron, technology efficiently reduces iron ore pellets into highly metallized hot or cold iron. Utilizing high operating pressure, the process uses reducing gases within a moving bed shaft furnace reactor to remove oxygen from iron ore pellets and lump ore. The process is independent of any
The Tecnored process is an innovative technology, with 103 registered patents in 27 countries. The Tecnored technology produces similar quality pig iron to the blast furnace in a comparable fashion, by feeding fuel (coal or carbon) and iron ore agglomerates into a furnace
iron ore. The product is called Direct Reduced Iron (DRI).15) Reduction shaft furnace is an effective process to produce DRI, and its developed worldwide, including Midrex, HYL, upper part of COREX etc.612) Many research related to the reduction shaft furnace had been reported.1325) For example, Kato et al.13) aimed to reduce CO
Subsequent pelletisation of magnetite ore is much easier, using the most economical vertical shaft kiln. Such pellet plants are available from 100,000 to 600,000 tons per year in China. Iron ore pelletisation, using vertical shaft kiln
