SYD-T224/224/224i Tester coke reactivity index and coke strength after reaction
    发布时间: 2014-09-24 15:31    

Coke is an essential raw material for the operation of blast, which acts as the primary source of heat, reducing agent, carburizing agent and most importantly the supporting spine of loose burden. The proportion of coke is gradually decreased with application of pulverized coal injection. With the degradation of coke structure during gasification, the important effect of metallurgical coke for gas and liquid permeability of burden becomes more and more significant. The reactivity of coke refers to its gasification ability with CO2, which can be used to evaluate the degradation behavior of coke during carbon solution reaction. This machine is developed based on the latest standards of  ISO18894 and GB/ T4000.
