The tunnel kiln process can reach higher metallisation levels of 90-92%, as compared to 86-88% in the rotary kiln. The first generation tunnel kilns used clay crucibles and the capacities were 10,000-25,000 tons per year. The DRI was in the 'pipe' shape. The second generation tunnel kilns used silicon carbide crucibles and the DRI was in ...

DRI production with syngas. The gas based direct reduction (DR) process is designed to convert iron pellet/lump into metallic iron by the use of reducing gases in a solid-gas moving bed shaft furnace. O2 is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metallized DRI.

DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H ...

DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.
