The process of Sponge Iron making aims at
removing oxygen from Iron Ore. When it occurs, the departing oxygen causes
micro pores in the ore body making it porous. The final product, when
observed, under a microscope resemble a honeycomb structure, with a look
similar to look of sponge as well as in texture.
The quality of Sponge Iron is primarily ascertained by the Percent of
Metalization (removal of oxygen), which is the ratio of Metallic Iron to the
total Iron present in the product. The Properties of Sponge Iron typically
produced and demand in the market are:
| FE: Total |
90-92 |
| FE: Metallic |
81-84 |
| Metalization |
90 +/- 2% |
| Sulphur |
0.03 Max |
| Phosphorus |
0.05 Max |
| Carbon |
0.10 Max |
| Gangue content |
6 - 8 |
| Physical Characteristics: |
|
| Size Lump |
+3mm |
| Fines |
-3mm |
| Bulk density |
1.6-2.0 MT / M3 |
| Inherent |
3.5 MT / M3 |
Required raw material for preparing the above quality Sponge. 1) Iron
Ore.
| FE content : |
62: or higher grade |
| Sulphur |
0.06: or lower |
| Phosphorus |
0.07: or lower |
| Tumbler |
0.82: or higher |
| Gangue |
8.00: or lower |
This provides secondary steel makers, flexibility in preparing their furnace
charge to produce finer quality steels. Some of the features of the Sponge
Iron produced are:
- High iron content and high degree of metalization
- Uniform and consistent quality
- Lower sulphur and phosphorus content
- Negligible tramp element
- Minimum dust generation during material handling
- Good 85 low ability in bins pipes & conveyors for continuous 85
trouble free charging
- Superior technical support to introduction furnace operators
We offer quality iron ores for various
industrial and engineering applications. These ores are procured from the
best mines, and are supplied to our clients at very competitive prices.
These are extracted with meticulous detailing by our skilled workmen. The
iron ore supplied by us forms the major component for the iron & steel
and downstream industries. We ensure complete satisfaction of our clients by
supplying custom and standard sizes of our iron ore.
To ensure better campaign life and output, the Iron Ore is made to undergo
a series of other tests like tumbler & abrasion indices, reduability
etc.
