composite pellet or mixture, very limited literature has been published depicting the layerwise analysis and the effect of relevant parameters on the reduction behavior of iron orecoal composite pellets in multilayer bed RHF. The amount of carbon in the composite pellet is an important parameter as it influences the extent of
The paired straight hearth (PSH) furnace is charged with coldbonded selfreducing pellets composed of iron oxide and coal. When the pellets are heated, the iron oxide is chemically reduced to produce a 95percent metallized pellet suitable for use in steelmaking in an EAF.
Iron ore is found in nature in the form of rocks, mixed with other elements. By means of various industrial processes incorporating cuttingedge technology, iron ore is processed and then sold to steel companies. The iron ore produced by Vale can be found in houses, cars and appliances.
The obtained charcoal was mixed with reagent grade hematite in the mass ratio of one to four. Then, a small amount of Bentonite was added to the mixture as a binder, and the charcoal composite iron oxide pellets were prepared and reduced at 1273, 1373 and 1473 K in nitrogen gas atmosphere.

gated the carbothermic reduction of composite pellets containing a hematite iron ore, coke or charcoal as carbonaceous material. Nagata et ) showed that pig iron was obtained from magnetite ore–coal composite pellets by microwave heating. Chen et ) indicated that microwave heating with carbothermal reduction can increase the metal
AbstractThe reduction of hematite iron ore fines by different carbonaceous materials in composite pellets in a onelayer bed under nonisothermal asymmetric heating from above is studied. Temperature measurements at various points in the bed show that there are large gradients both inside and outside the pellets, with the reduction fastest at the top where the temperature is highest.
direct use of noncoking coal as the fuel/reducing agent and lump ore as the iron oxide feed. While the use of fine coal via pulverized coal injection is available for both technologies, coal briquetting is applicable to the Corex only. By coal briquetting it is possible to mix lowquality, lowcost coal fines with coals of higher grades.
The book "Iron Ore – Coal / Coke Composite Pellets" has been written especially for the students of Metallurgical and Materials Engineering in general and in particular for the ...
iron ore with particle size 25 ～48 µm was appropriate for the reduction of iron orecoal composite pellets in the experimental conditions, and particle size 75 ～106 µm and 150 ～180 µm were insufficient to complete the reduction.
introduction. Iron ore pellets are used for the production of hot metal in blast furnaces and DRI/HBI in direct reduction processes. A blast furnace is a shaft furnace, which is charged with iron bearing materials (pellets, sinters and/or lump ore), reducing agents (metallurgical coke) and additives (limestone, quartz, BOF slag).
12 Effect of Volatile Matter Content of Coal on Carbothermic Reduction of Ore / Coal Composite Pellets Packed in a Tall Bed of DRI reached 95% and the iron productivity was nearly 100 kgFe/m2h over three fold of RHF''s produc tivity. The main factors to influence the behavior of carbothermic reduction include green ball properties,
or concentrate. Liquid iron is preferred to solid iron because there is no gangue and molten iron retains its sensible heat. Coal is the fuel of choice because of its abundance and lower cost. Use of coal directly also would eliminate the need for blast furnace coke, a costly commodity.
Abstract The effect of carbontohematite molar ratio has been studied on the reduction efficiency of iron orecoal composite pellet reduced at 1523 K (1250 °C) for 20 minutes in a laboratory scale multilayer bed rotary hearth furnace (RHF).
composite pellets or briquettes which could possibly enhance kiln productivity and efficiency. In order to explore the efficacy of iron orecoal composite pellets over indurated iron ore pellets, standard charging of concentric layers of separate iron ore, coal fines, or their mixture, these pellets were tested at 1200. oC in the tunnel kiln ...
The problem of re‐oxidation of sponge iron has been solved by the self shrouding with gaseous products due to (1) tall bed, (2) high process temperature, (3) high volatile coal and (4) fully oxidized flame to result in low coal rate and high metallized DRI.

Carbothermic reduction of iron oxide is an attractive mechanism to produce metallic iron, since it can directly utilise coal as both reductant and fuel. To improve energy efficiency and productivity of the metallic iron production based on this mechanism, the combustion bed process packed with the composites of iron oxide and coal powder was experimentally...
Smelting reduction of iron ore‐coal composite pellets has been carried out in an induction furnace. The pellets, tied with tungsten wire, were immersed into the liquid metal bath. The experiments were carried out in the temperature range of 1713 K to 1733 K.
