What are DRI Fines?

Direct Reduced Iron (DRI) fines are small particles generated during the production, handling, and transportation of DRI. These fines, though rich in iron content, pose challenges in storage, transportation, and usage due to their fine particulate nature. To address these challenges, briquetting DRI fines into compact and uniform briquettes has emerged as an efficient solution in steel production.

Advantages of DRI Briquettes in Steel Production

1. Environmentally Friendly

One of the key advantages of DRI briquettes is their significantly reduced dust generation compared to loose DRI fines. This makes them more environmentally friendly, enhances workplace safety, and minimizes potential hazards associated with fine particulate matter. Moreover, their uniform size and density ensure consistent feeding and controlled melting in electric arc furnaces (EAF), leading to improved overall energy efficiency in steel production.

2. High Iron Content

DRI fines have a high iron content, typically ranging from 65-68%, making them an excellent alternative to traditional iron ore. By utilizing DRI briquettes, steel manufacturers can reduce dependency on natural iron ore resources while benefiting from superior metallurgical performance and lower impurity levels. The high purity of DRI briquettes enhances the quality and overall properties of the steel produced, making them a preferred choice for manufacturers aiming to improve productivity and reduce costs.

3. Energy Efficiency

Briquetted DRI fines provide higher energy efficiency in steel production. Due to their uniform composition and compact structure, they enable better heat transfer and controlled melting in steelmaking furnaces. This results in optimized energy consumption and reduced operational costs, making the process more sustainable and cost-effective.

What Makes a Good Binder For DRI Fines Briquettes

To achieve high-quality DRI briquettes, the choice of binder is crucial. Jianjie binder offers several advantages in the briquetting process:

1. Powder Form: Easy to transport and does not stick to rollers, ensuring smooth processing.

2. Low Dosage & Cost-Effective: Requires minimal addition while maintaining strong binding properties.

3. High-Temperature Resistance: No cracking even at temperatures as high as 1200°C.

4. High Strength & High Qualification Rates: Produces durable briquettes with excellent mechanical strength.

5. Enhanced Redox Properties: Improves the metallurgical efficiency of the briquettes during steel production.

Conclusion

Briquetting DRI fines into durable briquettes offers multiple benefits, including reduced dust, higher iron utilization, improved energy efficiency, and superior steel quality. With the right binder, such as Jianjie binder, manufacturers can further enhance the briquetting process, ensuring cost-effective and high-strength briquettes.
