Innovations in blast-furnace coke

Abstract

The introduction of DK coking additive to the coal batch improves the metallurgical properties of the coke produced. The quality of coke produced exclusively from DK additive permits its effective use. When introduced in the axial zone of the charge hole, it forms an axial ventilation region and thus the hearth may be packed with coke that is not susceptible to wetting by slag melt.
