Mathematical models and expert system for grate-kiln process of iron ore oxide pellet production (Part I): Mathematical models of grate process
Grate process is an important step in grate-kiln pellet production. However, as a relatively closed system, the process on grate is inaccessible to direct detection, therefore, it is hard to control. As a resu...

Influence of flux additives on iron ore oxidized pellets
Six additives, i.e., limestone, lime, magnesite, magnesia, dolomite and light-burned-dolomite, were added for investigating their influences on the pellet quality. For green balls, adding lime and light-burned...
