User Of Sponge Iron DRI Is A Kind Of Porous Material Of Low Carbon Iron By Reducing From Refined Iron Powder. DRI Has Steady Chemical Elements...
Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BFBOF and ScrapEAF routes. In DRI, iron ore is reduced in its solid state – unlike BF process where a liquid metal is formed during reduction. DRI can then be transformed to steel in electric arc furnaces. DRI production is common in Middle East, South America, India and Mexico.

technology package to produce cast iron kom sponge iron. Annex (1) shows a quality control sheet of produced by using imported pig iron and locally sponge iron. It is quite obvious kom the microstructure (and other) analysis that the quality of productes are comparable. This reflects on the knowledge base of the metal industry.
The main types of plants involved in iron and steel industry are sintering plants, blast furnaces and steel works, direct reduction plants, ferroalloy production, rolling, scarfing, pickling, iron and steel foundry, and other technologies, such as argon oxygen decarburization, ladle metallurgy vacuum degassing.
The Emergence of Iron Smelting and Blacksmithing: 900 B. C. to the Early Roman Empire. The technology required to separate iron from its ores and convert it into durable and useful objects is far more complicated than that needed to work successfully with copper and bronze.

due to which it is named as sponge iron. It is seen that the growth of sponge iron industry in last few years is unremarkable and today India is the largest producer of sponge iron as it covers 16% of global output. Sponge iron is used as feedstock and a recognized alternative to steel scraps in iron and steel making processes.
quality sponge iron to be used by the Swedish steel industry as highpurity melting stock. for the production of special steels like toolsteel and stainless steel. Initial tests in 1937 showed that, owing to its high porosity, the sponge iron produced. by Höganäs could readily be comminuted to iron powder.
