  Efficient Conversion of Sponge Iron from Iron Ore-Coal Composite

  By Rajnish Kumar Rai, Dheeraj Kumar Verma

  Abstract: Today India stands as the largest producer of coal based sponge iron using calibrated ore and non-coking coal. Production of sponge iron, via the direct reduction route using rotary kilns, continues to experience significant growth in India. Direct-reduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. …

  Behavior of Iron Ores During the Sponge Iron Production Process

  By Rajnish Kumar Rai, Dheeraj Kumar Verma

  Abstract: Behavior of natural iron ores with coal from different mines were undertaken to achieve better quality of sponge iron during direct reduction. Iron ore is the raw material used to make sponge iron, which is one of the main raw materials to make steel. 98% of the mined iron ore is used to make steel. The paper gives the introduction about subject. It tells about the need of direct reduced …
