Direct Reduced Iron (DRI)
Direct Reduced Iron (DRI), also known as sponge iron, is a high-quality alternative to traditional iron production methods. Produced by reducing iron ore pellets or lump ore using natural gas in a direct reduction process, DRI offers several advantages, including high purity, low impurities, and customizable metallurgical properties. As a versatile raw material, DRI finds applications in various industries, including steelmaking, foundries, and powder metallurgy.
Key Features:
- High purity and low impurity content, resulting in superior steel quality.
- Customizable metallurgical properties to meet specific customer requirements.
Cold DRI (CDRI)
Cold Direct Reduced Iron (CDRI) is a variant of Direct Reduced Iron (DRI) that is cooled and compacted into dense pellets or briquettes without undergoing any further processing. CDRI retains the metallurgical properties of DRI while offering enhanced handling and transportation characteristics. With its high density and reduced reactivity, CDRI is ideally suited for use in electric arc furnaces (EAFs) and other steelmaking processes, where it serves as a premium feedstock for steel production.
Key Features:
- Dense pellets or briquettes with high mechanical strength and low reactivity.
Hot DRI (HDRI)
Hot Direct Reduced Iron (HDRI) is a variant of Direct Reduced Iron (DRI) that is discharged from the direct reduction reactor at elevated temperatures, typically above 650°C. HDRI retains its high temperature during handling and transportation, offering several advantages over cold DRI, including improved formability, reduced energy requirements for melting, and enhanced metallurgical performance in steelmaking processes.
Key Features:
- High temperature retention, allowing for direct charging into electric arc furnaces (EAFs) or other steelmaking vessels without preheating.
- Improved formability and flowability, facilitating uniform distribution and melting in the steelmaking process.
Hot Briquetted Iron (HBI)
Hot Briquetted Iron (HBI) is a compacted form of Direct Reduced Iron (DRI) that is cooled, compacted, and densified into briquettes at high temperatures. HBI offers several advantages over traditional DRI and other ironmaking feedstocks, including higher density, reduced reactivity, and improved handling and transportation characteristics. With its uniform size and shape, HBI is a preferred feedstock for electric arc furnaces (EAFs) and other steelmaking processes, where it delivers superior performance and productivity.
Key Features:
- Densely compacted briquettes with high mechanical strength and low reactivity, ensuring minimal fines generation and material losses.
- Uniform size and shape, facilitating automated handling, storage, and transportation operations.
