Sponge Iron
Overview
Sponge iron, also known as direct reduced iron (DRI), is a refined form of iron ore characterized by its metallic content ranging from 80% to 88%. Produced through a direct reduction process, sponge iron serves as a crucial raw material in the steel-making industry, particularly in the production of crude steel such as blooms and slabs.
Manufacturing Process
The reduction of iron ore to sponge iron takes place in a rotary kiln, which operates at specific rotational speeds and maintains temperatures between 800 to 1,100 degrees Celsius. The primary raw materials used in this process include:
- Iron Ore: The main source of iron content.
- Iron Ore Pellets: Enhancing the efficiency of the reduction process.
- Non-Coking Coal (Bituminous): Acts as a reducing agent.
- Dolomite: Serves as a flux in the reduction process.
Key Features
Substitute for Scrap: Sponge iron is an effective alternative to scrap metal in steel production, offering improved metallurgical properties.
High Purity: The direct reduction process ensures that sponge iron retains a high level of purity, contributing to higher quality steel.
