Abstract

The clinkering, coking, and lean components of the coking batch at AO EVRAZ NTMK are experimentally studied. On the basis of the laboratory coking of 67 versions of the production batch at AO EVRAZ NTMK, with different content and properties of the clinkering, coking, and lean components, the formation of the coke’s CSR and CRI values is analyzed. A mathematical model is developed for predicting the coke quality on the basis of the batch characteristics. The pulverized-coal consumption at the blast furnaces is predicted for wet- and dry-quenched coke produced from different batches at AO EVRAZ NTMK.
