Using the DRyIron (TM) process to produce value-added iron units

World demand for metallized iron continues to increase, keeping pace with s teelmaking requirements for lower-cost hot metal. Virgin iron ore and in-pl ant oxide fines can be reduced to direct reduced iron (DRI) and hot-briquet ted iron (HBI). Maumee Research & Engineering Inc. (MR&E) developed an impr oved coal-based process for the cost-effective production of either DRI or HBI Starting with dry compaction, the process combines the latest technolog y for material preparation, rotary hearth furnace construction and environm ental control. Coarse iron ore fines are blended with pulverized nonmetallu rgical coal to produce a highly metallized (>90%) product. This paper prese nts production and installation cost data based on operating and under-cons truction iron oxide reduction facilities.
