Iron Carbide (Fe3c) - an overview ScienceDirect Topics

Iron carbide production exploits the lower cost of ore fines compared to lump ore and pellets. The process consists of feeding preheated iron ore fines into a fluid bed reactor. A gas mixture (CH 4 , CO, H 2 , and small amounts of CO 2 and H 2 O) which is at 600°C and 1.8atm is forced up through the iron ore fines bed reducing it to iron carbide.

Process for Manufacturing of Iron Carbide – IspatGuru

Mar 11, 2018  Advantages of iron carbide and its production process consist of the following. It is the better charge material than other materials for the EAF since it contains around 6.0 % to 6.5 % C and is produced from virgin iron ore and hence it contains negligible tramp elements. Use of iron carbide in steelmaking processes results into a low content of N2 and H2 in the steel.

The Steel Making Industry

Coke is a solid carbon fuel and carbon source used to melt and reduce iron ore. Coke production begins with pulverized, bituminous coal. The coal is fed into a coke oven which is sealed and heated to very high temperatures for 14 to 36 hours. Coke is produced in batch processes, with multiple coke ovens operating simultaneously.

Iron carbide (Fe3C) is a chemical compound of 93% iron and 7% carbon in pure form. It can be used as the only feed for BOFs and EAFs. In that role it eliminates the need for coke ovens and the blast furnace, and all the ancillary equipment for coal and lime. The Iron Carbide process is a two stage fluidized bed process that operates at a lower temperature than other direct reduction processes.
