    Blast Furnace Ironmaking - an overview

    The ironmaking blast furnace (BF) is a very energy-intensive metallurgical process and the prime route for steel production, from which about 70% of the world’s steel consumption is produced (Geerdes et al., 2015). The BF system receives coke and ore solid raw material along with hot blast air and continuously produces hot metal as the main product, as well as top gas and slag

    Apr 04, 2012 The ironmaking process in the blast furnace is a heat and mass transfer process, and the furnace can be divided into different zones according to physical and chemical state of the feed and temperature. Figure 1.1.5 illustrates various zones of the blast furnace and feed distribution and materials flow [13]. Corresponding to each temperature interval, typical

    Before iron ore can be used, oxygen must be removed from it. Known as ‘reducing’, this can be done either in the blast furnace, where hot air is injected into a continuous feed of coke, sinter and lime, or by the direct reduced iron (DRI) process. The result from both is liquid iron, which is then transported to the basic oxygen furnace

    Oct 10, 2017 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. The iron ore is dressed or crushed into 0.5-1 in. chunks, which increases surface area for reactions. Magnetic

    What happens in the Blast Furnace? The purpose of a Blast Furnace is to reduce the concentrated ore chemically to its liquid metal state. A blast furnace is a gigantic, steel stack lined with refractory brick where the concentrated iron ore, coke, and limestone are dumped from the top, and a blast of hot air is blown into the bottom. All the three ingredients are crushed

    Jan 10, 2016 There are two theories on how the iron smelting was driven, one that the wind blasted in through the bottom opening providing air which heated the process and the other that the wind blew over the open top, creating a low pressure area along the inside front wall which sucked air in through the lower opening (Fig 2)

    Blast Furnace Plant The blast furnace iron making typically implies a reduction and smelting in a single reactor. It is operated on counter current principle. The charge descent in the downward direction and the blast (hot air) ascends from tuyeres. Therefore the residence time of the reducing gas inside the furnace is less

    Iron making. The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way

    12.5.1.4 Steelmaking Process — Basic Oxygen Furnaces - In the basic oxygen process (BOP), molten iron from a blast furnace and iron scrap are refined in a furnace by lancing (or injecting) high-purity oxygen. The input material is typically 70 percent molten metal and 30 percent scrap metal. The oxygen reacts with carbon and other impurities to

    Dec 08, 2020 Blast Furnace. The current blast furnace is a giant steel shell built like a cylinder and packed with heat-resistant bricks. For the coke steel making process, iron ore, coke, and limestone are pumped into the furnace from the top and eventually sink straight to the bottom, becoming hotter as they go down.In the upper half of the furnace, coke-burning gas releases

    How is a blast furnace made? A blast furnace is usually built with a steel case and bricks made of magnesium oxide or other refractory material inside the case. The hot furnace cannot melt these bricks. The furnace is cooled with water running inside part of the case and bricks. The process of making iron is simple

    Iron Making: Smelting. The blast furnace was where the smelting process was started. In 1646, the original blast furnace roared to life, lit with a 3000 degree fire that was kept burning 24 hours a day for months at a time. The blast furnace is where bog ore was smelted to create cast iron pig bars, so named because liquid cast iron was fed
