Sponge iron production in tunnel kiln – Aramico Company

Sponge iron production by tunnel kiln method was developed from 1911 as Höganäs method in Sweden. After many modifications, now this process is a sufficient and effective method for sponge iron production. The main advantage of tunnel kiln process is the possibility to build small plants with low investment costs which are feasible economically.

Sponge Iron - an overview | ScienceDirect Topics

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 ...
