Description

Preiser's Z94-8543-02, shown here, in conjunction with the Z94-8543-53 Tumbler provides a high-quality, precision system for determining Coke Reactivity Index (CRI) and Coke Strength After Reaction (CSR) to ASTM Standard D5341.  The ASTM standard was developed to simulate the major weakening processes - chemical reaction with carbon dioxide gas, and physical abrasion - encountered by coke lumps 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. The reacted and cooled coke is then transferred to the strength-after-reaction tumbler where it is tumbled for a specified number of revolutions.
