Briquetted DRI is a compact and stable product designed to optimise the use of DRI in the steel industry. By applying high pressure, DRI particles are bonded together, forming pieces with uniform shape and size. This dense structure reduces contact with air, thereby preventing rapid oxidation. Compared to ordinary DRI, briquettes perform better in maritime and land transportation and allow for long-term storage. Moreover, the uniformity of their composition and dimensions makes the melting process in furnaces easier to charge and more predictable.
Briquetted DRI is a compressed product made from DRI, produced to improve physical properties and enhance efficiency in steelmaking. By reducing porosity, it prevents rapid oxidation and preserves the quality of the iron until use. The high mechanical strength of the briquette makes it resistant to impact and pressure, ensuring safe handling and transportation. The use of briquetted DRI in electric arc and induction furnaces improves efficiency, increases melting speed, and reduces energy consumption.
Direct Reduced Iron (DRI) is one of the key raw materials in many steelmaking plants worldwide, serving as a high-quality iron source in steel production processes. One of the methods to improve its handling, storage, and reduce oxidation is the briquetting process, which is classified into two main types based on the temperature of the DRI fed into the briquetting machine: cold briquetting and hot briquetting.
In cold briquetting, DRI at ambient temperature is directly fed into the machine and transformed into Cold DRI (CDRI). In contrast, hot briquetting uses Hot DRI (HDRI) with a temperature above 650 °C, which after compaction is converted into Hot Briquetted Iron (HBI). This method results in higher strength, lower porosity, and improved quality of the final product, making its transportation and export safer and more cost-effective
helps reduce oxidation and maintain iron quality. These properties ensure minimal quality loss under various weather conditions and during both sea and land transportation.
Whether in the form of Cold DRI (CDRI) or Hot Briquetted Iron (HBI), briquetted DRI provides a stable and consistent feedstock for furnaces, improving melting efficiency.
