Since systems for examining coke quality are labour-intensive and time-consuming,
automatic coke sizing and shaping equipment has been assessed. Variations in coke
shape as well as size affect blast furnace permeability, so potential for replacing
abrasion-resistance testing has been investigated by examination of size and shape
changes between the oven wharf and the furnace. Results demonstrate the ability
of on-line monitoring to facilitate coke quality assessment, permitting
identification/correction of problems.
