Analysis of Direct Reduced Iron for rapid process control

In this data sheet we present a typical quantitative determination of the phase content as well as of process critical parameters for the production of direct reduced iron (DRI).

Direct reduced iron (DRI), also called sponge iron, is produced by the reduction of iron ore (in the form of lumps, pellets or fines) with a reducing gas (primarily hydrogen or carbon monoxide) produced from natural gas or coal. In order to achieve maximum efficiency of the production process, a number of parameters need to be monitored, such as metallic iron content (Femet), metallization (Metn), total carbon content (Ctot) and the mineralogical phase content.
