· Biswas A. Principles of blast furnace ironmaking: Theory and practice. Brisbane: Cootha Publishing House, 1981 528 p. The idea of writing this book came while I was engaged in the operation of iron blast furnace and sinter plant. The behaviour of the blast furnace has always appeared to the operators as an enigma.
blast furnace stoichiomelry–II. Preamble. In lecture 31 a simplified material balance is considered for ironmaking blast furnace and the results of material balance formulation are presented in the form RIST diagram.. In that it is considered that charge consists of pure iron oxide and coke and the product is hot metal containing carbon only.

are added at the top (Blast Furnace). Within the Blast Furnace, temperatures reach up to 2700 degrees Fahrenheit. The superheated furnace causes the coke to continually combust, which further intensifies the heat. This causes the ironore to melt, and molten iron, also known as hot metal, is produced.
· IRON MAKING AND STEELMAKING: THEORY AND PRACTICE by. Feb 29, 2008 Chatterjee has authored several books: Ironmaking and Steelmaking—Theory and Practice and Hot Metal Production by Smelting Reduction of Iron Oxide (both published by PHI Learning) as well as two other books entitled Beyond the Blast Furnace and Metallics for Steelmaking—Production and Use .
CO is the main reducing agent in the upper portion of blast furnace. Reactions in blast furnace Fe2O3 + 3C 2Fe + 3CO Fe3O4 + 4CO 3Fe + 4CO2 CO2 + C 2CO Overall reaction Fe2O3 + 3CO 2Fe + 3CO2 The liquid iron runs downward to the bottom of the furnace and is withdrawn through tap hole.
Iron blast furnaces prod uce molten iron (pig iron) that can b e cast (molded) into products ; however, the majority of pig iron is used as the mineral feedstock for steel production. Steel furnaces produce a molten steel that can be cast, forged, rolled, o r alloyed in the production o f a variety of materials. a Gerald Houck, "Iron and Steel."

avoided to take place inside the furnace. Theoretical calculation • shows that approximately kg of carbon is saved for every kg of limestone removed [: Principles of blast furnace iron making'':Theory and Practice (1981), Cootha, Australia, Ch VI]. The statistical analysis of the performance data of
· Combustion process. The iron in the processed ores must be dissolved out by chemical processes. This requires an element that binds oxygen more strongly than iron. This is exactly what carbon can do as a reducing carbon is fed to the blast furnace in the form of coke (pyrolyzed coal) from the coking sufficiently high temperatures, the carbon can participate directly in the ...
· Ironmaking Blast Furnace. Iron is made by reacting iron ore (iron oxide and impurities), coke (a reductant) and limestone (CaCO 3) in a blast furnace.. Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities.

BLAST FURNACE PRODUCTS AND THERE USE SIZE OF BLAST FURNACE Design of blast furnace is evolved through experience . Calculation of blast furnace size is empirical in nature. Hearth dia of possco b/f increases from Hearth area increased from 1660 mtr sq 3800 mtr sq . Now there are nearly 700 blast furnace available in world.
After the two oil crises, all of the 42 blast furnaces operating in Japan stopped injecting heavy oil by August 1982, and pulverized coal injection (PCI), which was first introduced at the No. 1 Blast Furnace of Nippon Steel''s Oita Works in June 1981, spread rapidly. By 1998, PCI was applied to all of the blast furnaces in the country,

· Modern Blast Furnace Ironmaking – An Introduction (Fourth Edition, 2020) describes the principles of the blast furnace process. As a starting point, the blast furnace is seen as a simple iron ore melter, while gradually the physical, chemical and metallurgical background of the blast furnace process is clarified.
prereduction process, more lowgrade iron ore is used for blast furnace process. This also makes it possible to maintain the quality of iron ore used for sinter and improves the properties of sinter. (7) The practice of blowing natural gas directly into the blast furnace is not uncommon overseas. In Japan, however, it can hardly
