Coke Reactivity Index (CRI) and Coke Strength After Reaction (CSR)
To determine the CRI/CSR of Coke. Complies with ASTM D5341. Advanced designed Coke Reactivity Applied Test System in conjunction with the Coke Strength Tumbler Test procedure provide a high quality, precision system for determining Coke Reactivity Index (CRI) and Coke Strength After Reaction (CSR) according to ASTM Standard D5341. The ASTM Standard was developed to simulate the weakening processes – chemical reaction with carbon dioxide gas, and physical abrasion – encountered by lumps of coal as they descend through a blast furnace. In accordance with the ASTM method, the system produces the coke/carbon dioxide reaction in a regulated atmosphere vessel within a high temperature furnace.
