IRON MAKING
Iron Making in an Integrated Steel Plant
Introduction
Iron making is the process of producing hot metal from iron-bearing raw materials for subsequent conversion into steel. In an integrated steel plant, ironmaking is supported by a series of upstream facilities that prepare and supply the required burden materials, coke, fluxes, fuel and utilities.
The major iron-making route in an integrated steel plant involves the preparation of iron ore through sintering and/or pelletizing, production of metallurgical coke, and reduction of the prepared iron-bearing burden in a blast furnace.
The main objectives are to:
- Prepare iron-bearing materials of suitable size and quality.
- Produce sinter and/or pellets suitable for blast furnace charging.
- Produce metallurgical coke with appropriate physical and chemical properties.
- Provide the blast furnace with a consistent burden.
- Reduce iron oxides to metallic iron.
- Produce hot metal of the required quality.
- Maintain stable and efficient blast furnace operation.
- Recover and utilize process gases and by-products wherever applicable.
Raw Material Handling
Raw materials such as iron ore, pellets, sinter, coke, limestone, dolomite and other additives are received, stored, blended and transported to the respective processing or consumption areas.
Typical operations include:
- a) Receipt and Unloading
Raw materials may be received through rail, road, conveyor or other transportation systems and unloaded using suitable handling arrangements.
- b) Crushing and Screening
Materials are crushed and screened to achieve the required size distribution. Oversize material is returned for further crushing where required.
- c) Blending and Storage
Different grades and sources of materials may be blended to maintain consistent chemical and physical characteristics.
- d) Conveying and Distribution
Conveyor systems, transfer towers, feeders, screens, crushers and stockyard equipment transport materials to the respective process units.
Sinter Plant
Sintering converts a mixture of fine iron ore, return fines, fluxes and solid fuel into porous, mechanically strong agglomerates suitable for blast furnace charging.
The major stages include:
Raw Material Proportioning

Return Fines Recycling
The sintering process improves the suitability of fine iron-bearing materials for blast furnace operation by producing a controlled-size agglomerated burden.
Pellet Plant
Pelletizing converts fine iron ore concentrate into relatively uniform pellets suitable for use in iron making.
Typical stages include:
Concentrate Preparation
↓
Grinding / Conditioning
↓
Additive Addition
↓
Mixing
↓
Green Pellet Formation
↓
Screening
↓
Induration
↓
Cooling

Pellet Storage
Pellet quality is influenced by parameters such as chemical composition, pellet size, strength and reducibility.
