Numerical simulation of the direct reduction of …
7-7-2013 · A mathematical model was established to describe the direct reduction of pellets in a rotary hearth furnace (RHF). In the model, heat transfer, mass transfer, and gas-solid stone reactions were taken into account. The behaviors of iron metallization and dezincification were analyzed by the numerical method, which was validated by experimental data of the direct reduction of pellets in a Si ...
Direct Reduction Process - an overview | …
DRI is also known as sponge iron, it is a solid-state direct reduction process (Fig. 2.6). Coal, dolomite and iron ore or pellets are fed into one end of a rotary kiln, while sponge iron and char are withdrawn from the other end. Primary and secondary airs are supplied to the kiln to initiate combustion and reaction processes (Choudhury, 2014).
