Sponge Iron Production Process Arij Trading Iron&Steel

Market share: About 23% of sponge iron total production. 4) Tunnel furnace process . This process is the oldest direct reduction method. In this method, Thermal coal is mixed with iron ore as a reducing agent. Natural gas generates the required reduction temperature, and reduction is performed on Silicon Carbide (SiC) Crucibles in a tunnel furnace.

SL/RN process Outotec

The SL/RN process was developed in the early 1960s by Outotec in collaboration with three US companies. The process principles are the basis for numerous rotary kiln plants and still represent the dominant technology for the direct reduction of lump ore or pellets using coal. Operates with the widest range of iron-bearing materials, such as
