The Hoganas Process Powder Metallurgy Beyond Discovery

Dec 17, 2020 The total time that a car is in the kiln is about 68 h. Gas burners heat 150 m (500 ft) of the tunnel to a temperature of 1260 C (2300 F) the remaining 19 m (62 ft) are cooled with circulating air. The tops of the kiln cars form the bottom of the heating chamber. Within the hot zone of the tunnel kiln, several chemical reactions occur.

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 8001200 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 ...
