Sponge Iron

The Sponge Iron manufactured at our units is distinct due to its high metallic content and consistent chemical and physical characteristics. This provides furnace owners flexibility in preparing their charge mix to produce finer quality than what is possible using steel scrap only.

CHARACTERISTIC REQUIREMENT
% Non-magnetic 1.0 Max.
% Metallic Fe 81 Min.
% Total Fe 91 Min.
Metallisation 88 Min.
%Phosphorous 0.07 Max.
% Sulphur 0.07%
% Carbon 0.3 Max.
% SiO2+ Al2O3 5 Max
Size A-grade lumps 5-18 mm (-5 mm 5% Max.) (+18 mm 5% Max.)
A-grade fines 0-6 mm (0 mm 10% Max.) (+6 mm 10% Max.)
Features
  • Very good reducibility because of high porosity (25-30%)
  • Spherical shape and uniform size give very good bed permeability
  • High strength (150-200 kg ) or more for acid pellets
  • Heat consumption is much less than that of sintering
  • High Iron content and uniform chemical composition, hence lower flux and fuel requirement in the furnace
  • Low FeO
  • Easy handling
  • Its Carbon & FeO is very excellent. Steel Mills who are using DRI for reducing the Carbon, the FeO in our pellet sponge is less which is the plus point for reducing the Carbon
  • Wearing of inner Lining will not take place , as in the Pellet making we are not using Lime
