Better Use of Enriched UK Mezhegeyugol Coal in Coking Batch

Abstract—Industrial coking data from Kuznetsk and Raspadsk concentrates consisting of coal from OOO UK Mezhegeyugol are analyzed to determine the strength M25 and M10 and the ratio CSR/CRI for the coke produced from such batch at AO EVRAZ NTMK. Preliminary limits are established on the optimal content of UK Mezhegeyugol coal in the coking batch. On the basis of industrial experiments, the optimal batch composition is determined, so that coke of satisfactory quality is produced at AO EVRAZ NTMK from batch with the maximum possible content of enriched UK Mezhegeyugol coal and the minimum content of third-party coal.
