Rotary Hearth Furnace Based Pig Iron This is the Latest Technology to Produce the Pig Iron or MS Iron out of the Iron Ore Fines and Non-coking Coal. In this Technology, the Coal Consumption is the minimal as compared to the Tunnel Kiln Process or Rotary Kiln Process. Through RHF, either Pig Iron (Fe=96-97% C=3.0-4.0%) or MS Steel (Fe=99% C=0.2% Mn=0.3% etc) or HBI (Hot Briquetted Iron) (Fe=92% C=0.25%) can be made, depending upon the requirement. The entire time for the Reduction, Melting and Product Out will be around 45 min, so the larger capacity of the Plants can be made. This process is also Lowest Space Consuming Plant. The Best Part of this Technology is that we can Product the Ferro Alloys too, like Ferro Nickel (Fe-Ni), Ferro Chrome (Fe-Cr) or Ferro Vanadium (Fe-V) etc from the same Plant, by implementing different Parameters of Operations. We can Control the Low Carbon Ferro Chrome, MS Steel and many more.
