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.
The present paper further extends the analysis 42 43 by omitting the simplifying linearization step, and to considering an optimization of the two On 44 objectives with respect to the state of a steel plant, where the blast furnace can act from the 45 46 traditional way of operation with moderately oxygen enriched hot blast to full oxygen 47 ly ...
The process starts in the center of the wheel with the three main ingredients of iron in the form of iron ore, coke and lime, which are fed into a blast furnace to produce molten iron. The molten iron is mixed with recycled steel scrap and further processed in a basic oxygen furnace to make steel. The electric arc furnace melts recycled steel ...

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 ].
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 .
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.
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.

Clinker is first produced in a kiln system from calcareous (limestone, chalk or marl) and argillaceous (clay or shale) materials, with addition, in some cases, of small amounts of corrective ...
The production of iron in a Blast Furnace is a continuous process. The furnace is heated constantly and is recharged with raw materials from the top while it is being tapped from the bottom. Iron making in the furnace usually continues for about ten years before the furnace linings have to be renewed.
May 10, 2013 · Fig 1 Typical flow sheet of pulverized coal injection in blast furnace. The process of coal injection. The PCI process is based on the simple concept of carrying the finely ground (pulverized) dried coal by a conveying gas (normally nitrogen) to the BF where it is distributed to different tuyeres and injected through a lance in the blow pipe.
