Characterization of Ajaokuta Coke for Blast Furnace Ironmaking
2006
The 300kg coke sample received from Ajaokuta Steel Plant was subjected to proximate analysis and pilot scale size distribution test. The proximate analysis showed that the coke contains 0.38%, 13.45%, 2.72% and 0.14% of moisture, ash, volatile matter and sulphur respectively; while size distribution test gave micum 10 and micum 40 of 3.62% and 89.67% respectively. Therefore, the coke satisfies the blast furnace requirements for moisture, sulphur and micum strength. However, its ash and volatile contents exceed the specified limits except for Indian standard practice.
