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).

CFD Investigation of the Effects of Iron Ore . Reducibility and Coke Reactivity on Blast Furnace Operation. In this paper, a computational fluid dynamics (CFD) model is employed to investigate changes in ore and coke reaction rates in the shaft region of a blast furnace. The CFD analysis shows that a specified combination of the reaction rates of ore and coke …

Blast furnace productivity and the influencing parameters. Blast furnace (BF) is a process of iron making. During mid eighties BF technology got established and left behind other technologies of iron making.
Blast Furnace Burden Preparation with Reference to High Ash Coke R. F. Jennings, A. M. Frankau THE primary objectives in iron smelting are high output, low coke, rate and smooth operation. The aspect of coke econonac is somewhat cotn-
Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and reduce the iron oxide to elemental iron mixed with carbon.
through concentration of large particles within the ore layers. coke layers are thicker than the ore layer as the coke is more permeable than the iron ore.Burden Distribution It is true that by reducing the range of lump size. . gas/solid contact can be improved. So. but complete elimination of the size variation is very difficult and under ...
· As a result of introduction of pellets in the Ijamu din blast furnace a coke rate decreases of 20-22 kg/tonne was expected. · Jindal has also set up a palletizing plant at Belga on for pellets to be charged in
Use of iron ore fines, coke breeze, metallurgical wastes, lime, dolomite for hot metal production Better reducibility and other high temperature properties Increased BF productivity due to higher softening temperature and lower softening –melting temperature range.

The effect of automatic process control on the blast furnace coke rate is in the range of 3 % to 5 %. Blast temperature is other parameter which influences the coke rate in a blast furnace. Blast furnace coke rate reduces by around 2 % with the blast temperature increasing by 100 deg C.
Reducibility is an ability of iron ore material to give oxygen from ferrous oxide to reducing gas with greater or smaller velocity. Its role increases in the process of blast furnace improving and the coke rate reduction. Reducibility is defined in accordance with Russian Federation State Standard 17212–84 (Russia).
Blast temperature is other parameter which influences the coke rate in a blast furnace. 3.1 % in the coke rate. softening temperatures greater than 1250 deg C.1 kg/sq cm there is a reduction of around 0. and closing of tapping after furnace becomes dry.
