Ironmaking Process Alternative Screening Study, Volume 1 ...
Jan 06, 2005 · Blast furnace ironmaking technology, by far the most important ironmaking process, is based on coke and iron ore pellets (or sinter) to produce liquid iron. However, there has been a worldwide effort searching for a more economical and environmental friendly alternative process for the production of liquid iron.

This extraction method is still used today. The bloomery is replaced with a blast furnace, but the chemistry is still the same. Iron ore, a type of coal called coke (which contains 85% carbon) and lime are added to the top of the blast furnace. Hot air provides the oxygen for the reaction. The temperature of a blast furnace can be up to 1200°C.

Oct 26, 2011 · Basicoxygen furnaces, which are loed at integrated steel mills in association with a blast furnace, are charged with the molten iron produced in the blast furnace and steel scraps. Typically, the proper basicoxygen furnace charge consists of approximately 10–20% of steel scrap and 80–90% of molten iron [ 1, 3 ].
Electric Arc Furnace Process
The blast furnace–BOF route produces almost 66% total crude steel, and EAF route accounts for about 31%, while the blast furnace–open hearth process, which dominated steelmaking in the first half of the 1900s, had only a share of about 3% left [7].
Fault Detection and Identifiion of Blast Furnace ...
The problem of fault detection and diagnosis for blast furnace ironmaking process is a long lasting and well research topic. Traditional methods like expert knowledge and fuzzy logic have been well developed in different kinds of expert systems [].However, constructing and maintaining an uptodate knowledge base is difficult.
blastfurnace
An important development in blast furnace technology, the pressurizing of furnaces, was introduced after World War II. By "throttling" the flow of gas from the furnace vents, the pressure within the furnace may be built up to atm or more. The pressurizing technique makes possible better combustion of the coke and higher output of pig iron.
