Iron processing, use of a smelting process to turn the ore into a form from which products can be fashionedIncluded in this article also is a discussion of the mining of iron and of its preparation for smelting Iron (Fe) is a relatively dense metal with a 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 using coke and limestone in a blast furnace It is then fed to a BOF in molten form along with scrap metal, fluxes, alloys, and highpurity oxygen to manufacture Iron and Steel Manufacturing IFC In his discussion of electricfurnace production of pig iron and pig steel before the Engineers’ Society of Western Pennsylvania, Dr J W Richards defines pig steel as “a metal with 22 per cent, or less of carbon, a very small amount of silicon and manganese, low in sulphur and phosphorus, and made directly from iron ore Pig Iron Manufacturing Process 911 Metallurgist
1A Manufacturing Process for Iron and Steel
The hot metal is decarburized to the required carbon content in the BOF The main reaction in this process is the oxidization of the carbon in the hot metal by both pure oxygen gas (O 2) and iron oxide (Fe 2 O 3) The residual oxygen, after contributing to Iron exists naturally in iron ore (sometimes called ironstone) Since iron has a strong affinity for oxygen, iron ore is an oxide of iron; it also contains varying quantities of other elements such as silicon, sulfur, manganese, and phosphorus Smelting is the process by which iron is extracted from iron ore(PDF) A Brief History of Iron and Steel Production Melting and pouring iron at 1,350 degrees centigrade is a spectacular and potentially violent process Safety is the highest priority in any foundry First the furnace is carefully loaded to ensure the correct chemical characteristics for the prescribed grade of iron are achieved The iron is then melted in the furnace and pouredCast Iron Production Hargreaves Foundry

23 The Höganäs Sponge Iron Process The Höganäs sponge iron process, is essentially a chemical process in which finely divided iron ore is being reduced with coke breeze yielding a spongy mass of solid metallic iron, which can readily be comminuted to iron powder The iron ore used at Höganäs is a magnetite slick (powdery Fe 3 O 4The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag What happens in the Blast Furnace? The purpose of a Blast Furnace is to reduce the concentrated ore chemically to its liquid metal Extraction of Iron Metallurgy Blast Furnace and THE MANUFACTURING PROCESS Iron ore is converted to steel via two main steps The first involves the production of molten iron and the second is that of actual steel manufacture The details of these steps are outlined below Step 1 The production of molten iron The Primary Concentrate is mixed with limestone and coal and heated The iron The Manufacture of Steel NZIC
