Influence of coal processed at Kuznetskaya enrichment facility and OUOU EZSMK on coke quality. 1. Laboratory studies

Аннотация

The components of the coal batch supplied to Kuznetskaya enrichment facility and OUOU EZSMK are studied experimentally, along with the other concentrates used in coking at AO Evraz ZSMK and other Kuznets Basin concentrates. On the basis of models of the concentrates available at Kuznetskaya enrichment facility and OUOU EZSMK, with different rank composition and properties simulating production conditions, various production batches for AO Evraz ZSMK are formulated and undergo laboratory coking. In addition, several production batches at AO Evraz ZSMK containing other Kuznets Basin concentrates are also studied. The maintenance of the required CSR/CRI ratio of the coke with variation in the coal available at Kuznetskaya enrichment facility and OUOU EZSMK is discussed.
