Characterization of Ajaokuta Coke for Blast Furnace

2013-12-24  In coke screening, the stabilized coke was screened through screens of round holes sizes 80mm. For micum drum test, 50kg of the coke screened in the coke screening stage not passing a round hole sieve of modulus 48 (63mm) was rotated 25 revolutions/min for 4 minutes and then subjected to coke screening again.

Blast Furnace Coke Hardness - Mineral Processing

2016-2-21  Changes in coke hardness affect the working of the blast furnace, for soft coke is an obstacle to proper furnace operation. Soft coke is due to a low hydrogen-oxygen ratio in the coal charged; increasing this ratio increases the hardness of the coke. ...

Why Use Coke for Blast Furnace Ironmaking not Use Coal

2019-10-6  The high-temperature CO2 gas reacts with the carbon in the coke to form CO, and the CO further reduces the iron ore to form molten iron. Carbon supply: The carbon content of pig iron is about 4%, all from blast furnace coke, accounting for 7%-9% of coke carbon content. Heating: The combustion of coke, injected fuel and external hot air provide ...

Blast furnace process - tec-science

2018-6-21  The combustion of coke produces hot gases consisting mainly of carbon monoxide, carbon dioxide, nitrogen and (gaseous) water. These hot gases rise up in the blast furnace and cool down. From a maximum of 2000 °C at the level of the hot-blast nozzles (tuyere), the temperature decreases to around 200 °C up to the throat.
