Direct Reduced Iron and its Production Processes IspatGuru

Iron ore is used mostly in pellet and/or lumpy form. Oxygen (O2) is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metalized DRI. In the direct reduction process, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion.

Introduction of Steelmaking Process with Resource Recycling

Steel scrap does not need reduction energy, unlike iron ore. Therefore, it is efficient in terms of recycling steel resources and suppressing CO2 gas emissions when melting large quantities of scrap. Various methods of melting scrap with converter have been reported, including a heat supply method and a steelmaking process using scrap melting, and scrap melting has been shown to be superior in ...

iron ore. His process involved grinding taconite to remove gangues and upgrading the iron ore (, an ore beneficiation process). The resultant highgrade ore is in the form of fine particles, as small as or less, which are not suitable for sintering. This issue led to the use of pelletizing. Pelletizing plants are expected to play an

Steel making process ArcelorMittal

There are two main processes for producing steel: by means of a blast furnace (= indirect reduction) in combination with a converter, or by means of an electric furnace. In the former process, iron ore is the main raw material. In an electric furnace, scrap iron is used and occasionally also sponge iron. Sponge is an intermediate product, which ...
