What is direct reduced iron (DRI)? definition and …
direct reduced iron (DRI): Alternative iron source produced by heating an iron ore (generally having 65 to 70 percent iron) at a temperature high enough to burn off its carbon and oxygen content (a process called reduction) but below iron''s melting point(1535°C or 2795°F). The output is sold as pellets or briquettes (called hot briquetted iron

Blast furnace process - tec-science
In the indirect reduction zone, the iron oxide contained in the iron ores is reduced by carbon monoxide gas, whereby the iron ores are not melted! Direct reduction zone If the iron ores, which have not yet been reduced, move further down in the blast furnace, then the carbon can also directly reduce the iron oxides contained in the ore due to the high temperatures.
