    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 ]

    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. A third group of iron-making techniques classed as smelting

    Iron is produced in blast furnaces by the reduction of iron bearing materials with a hot gas. The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter; flux as limestone, dolomite, and sinter; and coke for fuel. Iron oxides, coke and fluxes react with the

Then the iron derived after a long processing in the blast furnace is handed over to the iron and steel industry to make a huge amount of useful materials. Most of the iron, however, is used in the construction industry

    In the Bessemer process, molten pig iron from the blast furnace was charged into a large crucible, and air was blown through the molten iron from below, igniting the dissolved carbon from the coke. As the carbon burned off, the melting point of the mixture increased, but the heat from the burning carbon provided the extra energy needed to keep the mixture molten

    When iron making was properly established, two types of furnace came into use. Bowl furnaces were constructed by digging a small hole in the ground and arranging for air from a bellows to be introduced through a pipe or tuyere. Stone-built shaft furnaces, on the other hand, relied on natural draft, although they too sometimes used tuyeres. In both cases, smelting involved creating a bed of red-hot charcoal

Today’s steel is generally produced in one of two ways: Blast furnace: The blast furnace process, also known as the basic oxygen process (BOP), combines raw iron ore with small amounts of steel scrap metal into a furnace. Then, pure oxygen is

    Introduction. Iron making evolved over a few thousand years. Using the ancient bloomery method, iron ore was converted directly into wrought iron by heating the ore while at the same time melting the ore's impurities and squeezing them out with hand hammers. This is also called the direct process. By the 1100s water-powered hammers replaced

    The European iron workers knew the Easterners had better iron, but not the processes involved in fashioning stronger iron products. Entire nations launched efforts to discover the process. The first known European breakthrough in the production of cast iron, which led quickly to the first practical steel, did not come until 1740

    The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal is a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800 F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the volatile matter

    The process of making the various kinds of iron and steel is described below. The difference between iron and steel is based on the amount of carbon contained in the metal. If less than 0.1% carbon is present in the metal, it is termed wrought iron, and it remains a ductile metal that can be heated and welded, but not hardened; it can be

    In the BOF process, coke making and iron making precede steel making; these steps are not necessary with an EAF. Pig iron is manufactured from sintered, pelletized, or lump iron ores us-ing coke and limestone in a blast furnace. It is then fed to a BOF in molten form along with scrap metal, fluxes, alloys, and high-purity oxygen to manufacture
