Direct reduced iron (DRI), also called sponge iron, [1] is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) into iron by a reducing gas which contains elemental carbon (produced from natural gas or coal) and/or hydrogen. When hydrogen is used as the reducing gas no carbon dioxide is produced.
The HIsarna ironmaking process is a direct reduced iron process for iron making in which iron ore is processed almost directly into liquid iron ().The process combines two process units, the Cyclone Converter Furnace (CCF) for ore melting and pre-reduction and a Smelting Reduction Vessel (SRV) where the final reduction stage to liquid iron takes place.
Packaging of pre-reduced iron ore is evenly divided between sponge iron and briquettes. Sponges are a highly porous metallic product, close to the original ore but highly pyrophoric, which limits their transport. They are therefore often subjected to hot compaction, which improves both product density and handling safety. [10]
A bloomery is a type of metallurgical furnace once used widely for smelting iron from its oxides. The bloomery was the earliest form of smelter capable of smelting iron. Bloomeries produce a porous mass of iron and slag called a bloom. The mix of slag and iron in the bloom, termed sponge iron, is usually consolidated and further forged into ...
The Iron and Steel industry in India is among the most important industries within the country. India surpassed Japan as the second largest steel producer in January 2019. [ 1 ] As per worldsteel , India's crude steel production in 2018 was at 106.5 million tonnes (MT), 4.9% increase from 101.5 MT in 2017, which means that India overtook Japan ...

Carbon content in the product can be controlled by changing the quantity of coal in the furnace. Noncorroding chromium steel could also be produced by using impure ore instead of hematite. Likewise, spongy iron can be cast by using coal-lime briquettes. Additionally, the Flodin furnace also can be used to produce so-called 'soft steel'. [1] [2 ...
