Microwaves Applied to Carbothermic Reduction of Iron Ore Pellets
Results of reducibility tests of reduction conducted on iron ore pellets with carbon are presented in this work. Work done is centered on reduction kinetics using carbon as reducing agent with conventional heat supply (heat transfer process) compared with reduction kinetics where heat is supplied by microwaves to the whole volume. Ore used in this work is called "Alzada" which has reducibility ...
متن کاملMathematical Model For Energy Saving In Induration Of Iron Ore Pellets Containing Solid Fuel
Mathematical model for a pilot scale iron ore pellet induration furnace has been developed which considers the process of induration including the reactions of limestone, magnetite and coke. The differential equations of energy, mass and momentum are solved simultaneously. The profiles of temperature, pressure and concentration are obtained. Performing separate experiments on sub processes; dry...
متن کاملEffect of Using Oxygen-Enriched Gas during Induration Process of Iron Ore Pellets Containing Solid Fuel
In this research, the effects of oxygen injection during the induration process were studied in order to improve the quality specifications and increase the rate of production of the iron oxide pellets. Several experiments were carried out in palletizing pilot plant in different conditions of oxygen injection. The results suggested that if only the extra oxygen was injected into the furnace in ...
متن کاملHow to Measure Phase Distribution and Degree of Sintering in Iron Ore Pellets
Iron ore pellets are made from refined and ground ore that is balled into spheroids and then heat treated. Pellet properties are measured through standardized physical, chemical and metallurgical tests to guarantee a high quality end product. However to better understand the oxidation and sintering of iron ore pellets one has to study the microstructures. This paper provides a proof of concept ...
متن کاملAn Investigation on the Reduction of Iron Ore Pellets in Fixed Bed of Domestic Non–Coking Coals
In this study, the isothermal reduction of iron oxide pellets, made of Iranian Chadormalo, Gole-gohar, and Sangan iron ores, was investigated in the temperature range of 900-1100°C. Tabas, Pabdana, Babnizoo, Karmozd, and Shahrood domestic coals were used as reductants. Parametric studies were performed and the effects of such factors as temperature, average particle size of iron ore and coal fi...
