Utilization of Coke-Breeze Briquets in Hot-Metal Production at PAO Koks

Abstract

Experimental briquetting of substandard coke breeze at PAO Koks is considered. The briquets are characterized by drop strength of 99.9%. Their ash content is close to that of the coke breeze, thanks to the low ash content of the binder. The briquettes’ elevated yield of volatiles is associated with the binder’s high yield of volatiles. In industrial experiments, the briquets are used to produce hot metal in a cupola furnace. Replacement of 20% and 40% of the coke in the batch by the briquets does not impair the smelting process.
