How iron is made

 · Perhaps the best illustration of this slow progress has been the history of the HIsmelt (High Intensity) process, promoted by its proprietor as "the world''s first commercial direct smelting process for making iron straight from the ore" (Rio Tinto, 2014). Its history goes back to the development of bottom-blown oxygen converters and combined steelmaking by Klöckner Werke in the early 1970s, and its key feature is the injection of coal and fine ore …

Iron ore pelletizing

Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore pellets. These are typically fed to a blast furnace or DRI plant as part of the process to make steel. Expertise. Designed and supplied the largest straight grate …

Iron Ore Sintering Process in Steel Manufacturing

Sinter is the primary feed material for making iron in a blast furnace. Sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control the chemistry and then igniting it at 1200°C in a continuous belt-fed furnace.
