Installation for determination of coke strength after reaction with carbon dioxide (CSR and CRI).

The machine is designed for testing coke according to GOST R 50921 (ISO 18894) "Coke. Determination of reactivity (CRI) and coke strength after reaction (CSR)" (Edition with Amendment). The facility allows the determination of coke reactivity (CRI) values to carbon dioxide and coke strength after reaction with carbon dioxide. (CSR). The facility simulates the chemical, thermal and physical factors leading to the coke breakdown in a blast furnace and evaluate the changes that occur to the coke. The method consists in the reaction of coke with carbon dioxide at a temperature of 1100°C, determination of the mass of the of the coke residue after the reaction, mechanical treatment of this residue in a drum at room temperature and subsequent sieving. temperature and subsequent sieving. At the same time, control of the heating temperature regime, gas supply mode (CO2 and N2), drum rotation speed are controlled automatically by the control unit according to the standard and the preset programme.
