The product of such solid state processes are called direct reduced iron. The books you read, it could be more valuable than a luxury car that is awarded to you. Chapter 6 Melting of Metallics Including DRI Use of DRI (sponge iron) and other metallics like scrap, pig iron, hot metal, . The sponge is removed from the furnace, called a bloomery, and repeatedly beaten with heavy hammers and folded over to remove the slag, oxidise any carbon or carbide and weld the iron together. described as follows: Krupp-CODIR (Coal Ore Direct Iron Reduction) Process The Krupp-CODIR process [6,4,11] was .Go to Notification SPONGE IRON PRODUCTION BY DIRECT REDUCTION OF IRON OXIDE : Production and Use Banshidhar Pandey. (November 2013) Click [show] for important translation instructions. 2 R. This article has multiple issues. The iron oxide in either lump, conceptrate, or pellet form is reduced at 800-1050 C (1472-1922 F) by interaction with reductants (H2 CO) derived from natural gas or coal. One exception is the fluidized bed process which requires sized iron ore particles. Hot direct reduced iron (HDRI) is iron not cooled before discharge from the reduction furnace, that is immediately transported to a waiting electric arc furnace and charged, thereby saving energy.


A lot of reading is a way to be a lucky person. This treatment usually creates wrought iron with about three percent slag and a fraction of a percent of other impurities. This makes for an energy-efficient feedstock for specialty steel manufacturers which used to rely upon scrap metal. Directly reduced iron is highly susceptible to oxidation and rusting if left unprotected, and is normally quickly processed further to steel.[citation needed] The bulk iron can also catch fire since it is pyrophoric.[5] Unlike blast furnace pig iron, which is almost pure metal, DRI contains some siliceous gangue, which needs to be removed in the steel-making process. Retrieved August 18, 2016. Though reading is finding the most valuable treasure.


this method produces 97% pure iron. &.more Copyright 1997 Hylsa, S.A. 2015. The book is primarily intended for the undergraduate and postgraduate students of metallurgical engineering. In this world we will find many illusions. The advantage of the bloomery technique is that iron can be obtained at a lower furnace temperature, only about 1,100C or so. ^ Hattwig, Martin; Steen, Henrikus (2004), Handbook of explosion prevention and protection, Wiley-VCH, pp.269270, ISBN978-3-527-30718-0. DRI Basics For a description of the basic fundamentals of direct reduction and the production of DRI, click here. this method produces 97% pure iron.


The direct reduction process can use natural gas contaminated with inert gases, avoiding the need to remove these gases for other use. Fruehan, et al. It is also a must-read for researchers, technologists and process metallurgists engaged in the rapidly developing field of direct reduction of iron oxides, which is of critical importance for India and other developing nations that are beginning to play a major role in global steelmaking."% Click Media Download %&Sentences Definition&PDF (Portable Document Format) EBOOK (Electronic Book)WORD (Document)HTML (Hyper Text Markup Language) EPUB (XML-based)RTF (Rich Text Format)TXT (Plain Text)KPF (Kindle Package Format) By reading the world we enter into our minds.
