shaft furnace for iron ore pellet

Jul 15, 2017· Iron ore pellets were reduced at 450–600 °C under load of 0.4 kg/cm 2 by simulating upper shaft furnace conditions , . For each reduction experiment, iron ore pellets were heated to the required temperature and then reduced for 60 min in reducing gases (listed in Table 2) at flow rate of 0.6 m 3 /h. Subsequently, the reduced samples were cooled to room …

The MIDREX®shaft furnaceis designed to operate with a combination ofpelletsand lumporesvirtually in any proportion. This allows the plant operator to maximize productivity at the lowest cost. MIDREX® plants are reported to have processedironoxidepelletsand lumporesfrom over 50 sources around the world

Shaft furnacesusepellets(produced in the same way aspelletsfor the BF), or lump ore. Raw material forpelletsis produced by crushing and grinding low-gradeironores—typically of the taconite class and finer than 325 mesh (0.044 mm)—and magnetically separating the iron oxide (magnetite, Fe 3 O 4 ) from the siliceous gangue

introduction toiron ore pelletsandpelletizingprocesses

It is an agglomerating process of converting iron ore fines into ‘uniformed sized iron ore pellets’ which can be charged directly into a blast furnace (BF) or into a vertical furnace or rotary kiln normally used for the production of direct reduced iron (DRI). The iron ore pellets are shown in Fig 1. Fig 1 Iron ore pellets

Magnetiteoreconcentrate gets re-converted into hematiteorein the pelletisation, as it is an oxidation process. The hardening ofpelletscan be done by the verticalshaftkiln or travelling gratefurnacecum rotary kiln. The verticalshaftkiln needs lower investments &is suitable for small capacities of 100,000 tons to 600,000 tons per year

introduction toiron ore pelletsandpelletizingprocesses

Iron ore pelletis a kind of agglomerated fines which has better tumbling index when compared with theiron oreand it can be used as a substitute for theiron orelumps both in the BF and for DRI production.Pelletshave good reducibility since they have high porosity (25 % to 30 %). Normallypelletsare reduced considerably faster than sinter

Jul 10, 2017· Theiron oreproduction has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content ofironinoredeposits has deteriorated and low-gradeiron orehas been processed. The fines resulting from the concentration process must be agglomerated for use inironand steelmaking. This chapter …

dri production internationalironmetallics association

Direct reduction ofironis the removal of oxygen fromiron oreor otherironbearing materials in the solid state, i.e. without melting, as in the blastfurnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal.Iron oreis used mostly inpelletand/or lumpy form
