Coke Quality and Blast-Furnace Performance

Аннотация

On the basis of six-year operational data for a 5000-m³ blast furnace, the dependence of the coke consumption on its strength M₂₅ and M₁₀ and the content of the >80 mm fraction is calculated by different methods. The quality of the coke has a clear influence on coke consumption and blast-furnace economics. As an illustration, for some of the equations derived, means are established for predicting the economic benefit associated with improving coke quality and reducing its consumption, in specific blast-furnace conditions.
