Coke Reactivity Index / Strength Test System (CRI CSR)The Coke Reactivity Index / Strength Test System CRI CSR Test System is an automatic device for determination of the Coke Reactivity Index (CRI) and Coke Strength after Reaction (CSR).
This Coke Reactivity Index / Strength Test System device is fully compliant with the specifications in the International Standards ASTM D 5341 and ISO 18894.
Both indexes C.R.I. and C.S.R. are probably the most important parameters used for assessment of the quality of metallurgical coke.
The CRI Test system Double Oven improves the number of tests that can be performed with a single equipment. At the end of the test in the first oven it is possible to start immediately a new test on the second oven. The time waiting for the cooling down of the oven is saved and available for testing another sample. The system is provided with an independent Nitrogen line that can be switched on to the reaction tube where the test is just finished to allow the cooling down of the sample in an inert atmosphere (as prescribed in the standards).
