The Midrex direct reduction technology has evolved dramatically during the past four decades from capacities of just 150000 t/a to capacities now approaching 2 million t/a. New Midrex projects recently contracted in the Middle East, Russia, Malaysia and Trinidad have shown a dominant trend in the use of hot DRI for maximising steeimaking benefits. These current hot DRI projects underway also represent a variety of solutions in the transport of hot DRI from the Midrex plant to the adjacent melt shop. This paper will discuss current state-of-the-art technology including capacities, consumption figures, iron yield, hot DRI transport methods and environmental benefits (i. e. CO_2 emissions). Furthermore, a brief of current projects and their integration with adjacent steeimaking facilities will be discussed.
