Reduction of Iron Ore Pellets with a particular percentage of binders i.e. 2 of Dextrine and 2 of Bentonite was carried out for the temperature range 900 to 1050 C. In reduction kinetic study the most satisfactory model was to taken, the slope of the initial linear region.
Mar 23, 2020 The iron‐bearing materials consist of iron ore pellets, lump ore, and sinter. When the charge material descends, it is reduced by CO and H 2. In the ideal situation, iron‐bearing materials reduce fast and remain in the solid form in as high temperatures as possible.
Abstract Results of reducibility tests of reduction conducted on iron ore pellets by carbon are presented in this work. Work done is centered on reduction kinetics by carbon with conventional heat.
Abstract. A new iron making process using carburized pre reduced iron ore pellets and microwave heating is investigated. The pre reduced pellets, with a porous structure, and fine particles are carburized homogeneously at 400–650 C in a CO atmosphere.
The Benefits of Ore Pro Technology. The unique features of Ore Pro's Technology provide significant advantages over conventional pellet processing plants, such as Environmentally friendly independent emission monitoring of the demonstration plant has recorded very low levels of NOx , SO x and CO 2 during normal operation.
Why use microwave energy Our process is unique in that it uses microwave energy as the sole heat source for drying, preheating and induration (oxidizing and hardening) of ‘green magnetite’ iron ore pellets. The major advantages of using microwaves for magnetite processing are rapid heat transfer, volumetric and About Ore Pro Technology.
Reduction Of Iron Ore By Charcoal Under Microwave Irradiation 45 Table 2. XRF data of the sample (2000 Watt) Based on table 2, the longer irradiation time, the greater Fe content in the sample. The highest Fe content was reached by microwaves heating for 50 minutes in 2000 Watt power supply, approximately 77.29 .
The reduction of iron oxides using microwave energy as heating source has been previously investigated. Ishizaki et al. (2006) investigated the microwave reduction of magnetite ore–coal composite pellets in a nitrogen gas atmosphere. They observed by means of XRD analysis that the reduction of magnetite started at about 800 C and.
By different mechanisms, iron ore and moisture are the materials that control the heating by the microwave 12, 19. In the case of iron ore pellets, Athayde et al. (2018) 13 explained that moisture plays an important role as an better absorber of microwave and convert the energy into heat. Despite of other carbon based materials, coal is a poor.
May 09, 2016 Results of reduction tests conducted on iron ore pellets with carbon are presented in this work. Work done is centered on reduction kinetics using carbon as the reducing agent with a conventional heat supply (heat transfer process) compared with reduction kinetics where heat is supplied by microwaves to the whole volume.
MICROWAVES APPLIED TO CARBOTHERMIC REDUCTION OF IRON ORE PELLETS.
The subsequent microwave reduction tests showed that the core shell metallized pellets with the total iron content and metallization degree of 89.15 and 95.52 , respectively, could be obtained.

We used a microwave generator of 2.45 GHz with variable power up to 3000 W. Self‐reducing pellets under argon atmosphere, containing iron ore and petroleum coke, with 3.5 g of mass and 15 mm of diameter were declined.
Pellets of the ore containing various blends of uncharred ‘pito’ and charred ‘pito’ waste with HDPE were irradiated in a domestic microwave oven and the extent of reduction was determined after 40 min of irradiation. It was observed that highly.
