Modification of Refractory Components in Russian Coke-Oven Linings

Abstract

To date, Giprokoks designs have been used for all Russian coke batteries. The condition of these coke batteries has been deteriorating from year to year. The mean life of Russian coke batteries is 32 years, with values of 35 years for OAO EVRAZ ZSMK, 40 years for OAO MMK, 33 years for OAO Altai Koks, and 30 years for PAO Severstal’. The condition of the coke ovens determines the stability of steel output. The Russian coke industry faces the challenge of renewing (modernizing) its worn-out coke batteries. Changes are proposed here in some refractory components used in coke-battery linings. These proposals may be of interest to coke-battery designers and to contractors preparing for the reconstruction (or construction) of coke batteries.
