New smelting furnace enables the use of lower-grade ore in DRI ironmaking

In late October, Metso Outotec Corp. (Helsinki, Finland; www.mogroup.com) introduced the DRI (direct reduced iron) Smelting Furnace to substitute blast furnaces used in iron- and steelmaking. The furnace was developed to tolerate high-slag volumes, which are problematic for a conventional…
