TGC Iran – Premium-Quality Iron Ore Pellets for Modern Steelmaking
Iron ore pellets are one of the most important intermediary products in the steelmaking value chain — bridging the gap between raw iron ore and final steel products. At TGC Iran, we produce and supply iron ore pellets with consistent quality, high iron content, controlled size, and excellent mechanical properties, tailored to meet the demands of blast furnace and direct-reduction (DRI) steel plants.
After mining and beneficiation of raw iron ore (or concentrate), the fine iron-bearing powder is mixed with binding agents such as bentonite, limestone or dolomite, moisture, and other additives. Through a sequence of agglomeration — in pelletizing drums or discs — the mixture forms spherical pellets. These “green pellets” are then dried, hardened (indurated) in kilns at high temperature (usually 1200–1300 °C), cooled down, and screened for uniform size. The result: dense, hard, spherical pellets with controlled porosity and excellent metallurgical properties.
Pellets are sized typically between about 6 and 16 mm in diameter. Their iron content typically ranges from around 63 % up to 70 % (often ≈ 65 %) after proper processing — depending on the raw material and beneficiation process.
Key Quality Parameters of Pellets
When evaluating the quality of iron ore pellets, the following parameters are critical:
Iron (Fe) content: High Fe grade reduces the amount of gangue and slag, improving furnace yield and efficiency.
Impurities (SiO₂, Al₂O₃, P, S, etc.): Lower impurity content leads to higher quality steel and reduces furnace issues.
Mechanical strength (compressive strength, abrasion resistance): Ensures pellets survive handling, transport, and loading without excessive breakdown.
Porosity and structure: Proper porosity allows efficient gas-solid interactions inside furnaces, which improves reduction reactions and energy efficiency. Wikipedia+1
Size uniformity: Uniform pellet size ensures even burden distribution in the furnace, stable airflow, predictable reduction behavior
Using high-quality iron ore pellets brings several advantages compared to raw ore or simple concentrate:
Improved Furnace Efficiency: Pellets have uniform composition and porosity, which improves gas flow, reduction speed, and thermal efficiency in blast furnaces or DRI furnaces. Wikipedia+1
Reduced Fuel and Energy Consumption: Because pellets are already agglomerated and have optimal reducibility, less coke/fuel is required per ton of iron produced, lowering energy costs. IIM Delhi+1
Lower Slag Volume & Waste: Better chemistry and lower impurities mean less slag formation, improving yield and decreasing waste materials. IIM Delhi+1
Enhanced Operational Stability: Uniform pellets reduce chances of segregation, blockages or uneven burden distribution in furnaces — leading to smoother, more reliable production runs. Beytoote+1
Logistics, Storage and Handling Benefits: Pellets are mechanically robust, have standard size and shape, making them easier to transport, store, and feed into furnaces compared with fines or raw ore. Wikipedia+1
Environmental and Economic Benefits: Lower energy, lower waste, higher yield — all contribute to cost-effectiveness and reduce environmental impact. Green Gubre Group+1
TGC Iran – Reliable Supplier of High-Grade Sponge Iron for Modern Steelmaking
Sponge Iron (also known as Direct Reduced Iron, DRI) is a high-purity metallurgical product obtained by reducing iron ore in the solid state — without melting — by removing oxygen from iron oxides using reducing agents (such as natural gas, syngas, or coal gas). Wikipedia+2EMW Stahl-Service-Center+2
At TGC Iran, we supply sponge iron that meets stringent industrial standards: high metallic iron content, low impurities, consistent quality — ready to serve as raw material for electric arc furnaces (EAF), induction furnaces, and other steel production processes.
What is Sponge Iron and How It’s Produced
Process: In the direct-reduction process, iron ore (lumps, pellets or fines) is subjected to a reducing atmosphere (gas or coal-based) at temperatures well below the melting point of iron (typically 800–1200 °C). Oxygen is removed from the ore, producing metallic iron in a porous, sponge-like form. EMW Stahl-Service-Center+2Wikipedia+2
Structure and Composition: The resulting sponge iron — because of its porous, honeycomb-like structure — has high metallic iron content (metallic iron percentage can be quite high), low impurities (such as sulfur, phosphorus and other undesired elements), and stable chemical composition. gamma corporation+2Vertix+2
Key Advantages and Why Sponge Iron Matters in Steelmaking
Using sponge iron (DRI) offers multiple advantages over traditional raw iron ore / scrap:
High Purity & Consistent Quality: Sponge iron’s low impurity and predictable composition yield cleaner steel with fewer tramp elements, ensuring higher-quality final products. AISCO+2Sree Metaliks+2
Reduced Energy Consumption and Environmental Impact: Because direct reduction does not require melting the ore and often uses natural gas — rather than coke — the process consumes less energy and emits fewer pollutants. EMW Stahl-Service-Center+2SaminHadid+2
Excellent Feedstock for EAF / Induction Furnaces: Sponge iron is widely used in electric-arc and induction furnaces as a substitute or supplement for scrap metal, allowing better control over chemistry and quality of steel. Wikipedia+2AISCO+2
Operational & Economic Benefits: Its stable quality and higher iron content improve furnace efficiency, reduce slag formation, and lower fuel/material consumption per ton of steel produced. Adukia Industries+2FE Techno+2
Typical Applications of TGC Iran’s Sponge Iron
Sponge iron supplied by TGC Iran can be used as:
Material for production of billets, blooms, slabs, and various steel products — including construction steel, structural profiles, rebar, and other long products.
A reliable alternative to scrap metal, especially where scrap quality is inconsistent or scarce. Satyam Iron & Steel+2Junying+2
