Direct Reduced Iron Process Flow

Direct reduced iron process - tec-science

21-06-2018  Direct reduced iron (DRI) process. In addition to the process route via the blast furnace process, there is another option for extracting crude steel from iron ores using the so-called direct reduced iron (DRI) process (secondary route).The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure.

Direct reduced iron - Wikipedia

Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting ...

More

Direct Reduction Process - an overview

The sponge iron formed in the direct reduction process is then melted in an electric arc furnace. In these processes, the iron oxides in the ore are reduced to metallic iron. In the next step, the raw iron is usually dropped into a torpedo ladle car where reagent is added to purify the iron from sulfur.
