Abstract

Direct Reduced Iron (DRI) and Hot Briquetted Iron (HBI) are premium sources of metallic iron units for the electric arc furnace, due to their nature as virgin iron units, with a high content of metallic iron, a controlled amount of iron carbide, and practically free of residual elements. About 80% of the world DRI/HBI capacity (90% actual production) is shared by two natural gas-based processes. One of them is the HYL direct reduction technology, which has demonstrated its flexibility and reliability through the operation of different industrial plants worldwide. Since 1979, Ferrostaal has developed and built HYL DR plants in Mexico, Indonesia, Malaysia and Russia, for a total capacity of 5.5 Million ton/year of DRI/HBI. All of these projects were specifically adapted to the particular conditions and needs of each user and the DR plants have fully proven their reliability through their operating performance. This paper describes the characteristics and features of HYL DR plants built by Ferrostaal, indicating the flexibility of the HYL technology and the capabilities of Ferrostaal as General Contractor for an optimum project development. A description of the latest FS/HYL developments, such as the self-reforming process and the optimized Mini-Module concept is also included.
